Top 10 Enterprise App Development Companies 2026:#1 Frenchy Digital

The first document an enterprise buyer sends is often not a brief. It's a security questionnaire, and one of the first questions is whether you hold a SOC 2 Type II report.

We don't, and I say so on that row. But those questionnaires taught me what enterprise buyers actually screen on, and it isn't anything you'll find in the usual "best enterprise app developers" list.

Those lists rank on apps launched, clients served, awards won and a star rating from a review site. An enterprise security team doesn't read any of that. It asks for the certificate, the integration history, the contract terms and who owns the code.

So here is my claim, with the date on it. On September 30, 2026 I scored ten enterprise app development companies on six things a procurement team can check from a public page in about fifteen minutes per firm. ScienceSoft came first with 11 of 12. The average was 6.7.

To be clear about the conflict up front: I run Frenchy Digital, which builds apps and platforms for companies of every size. It isn't in the scored table. It gets its own disclosed section near the end, where I score it on the same rubric. It gets 9 of 12, which would put it second, not first, and I explain why it's still my pick for one kind of buyer and who should pick someone else.

If you haven't yet decided whether to build at all, start with our enterprise build vs buy vs low-code decision guide. This article assumes you've decided to build and need a shortlist of companies.

Most rankings of enterprise app development companies fail for three reasons: the author is a contestant, the list mixes app studios with global outsourcers, and the scores rest on numbers only the vendor can check.

The first is common across our industry. Agencies publish "top enterprise developers" lists and put themselves near the top. I'm not above the temptation, which is why my own company sits outside the table.

The second is an enterprise problem specifically. A list that puts a 150-person app studio next to a company with hundreds of thousands of staff isn't comparing like with like. Those firms sell different things, through different procurement routes, to different people inside your company.

The third matters most. Enterprise vendor homepages are covered in counters: thousands of projects delivered, thousands of clients, top rankings from review sites. Nobody outside the vendor audits any of them, and there's no public registry of who built which internal app. Most enterprise work is under NDA, which makes the counters even harder to check.

The wrong model is that a ranking tells you who builds the best enterprise software. The real model is that a public ranking can only measure what companies disclose and what a third party confirms. Delivery quality you judge yourself, through references and a paid discovery phase.

Why does that distinction matter more here than for a consumer app? Because you can't download an enterprise app from the App Store and try it. The work is behind a corporate login. So the paperwork (certificates, contracts, named references) carries more of the weight than it would anywhere else.

Before scoring anyone, each candidate had to pass one test: named enterprise app or platform work on its own site, sold as a build rather than as staff hours alone, and no acquisition or merger of the firm from 2024 to 2026.

A directory profile didn't count. The company's own case studies, client pages or homepage had to show enterprise work I could open. I also kept the list to firms whose main offer is building apps and platforms, not general IT outsourcing.

I started from roughly 15 names that recur across enterprise developer lists and the ranking brief for this round, then cut. Here's who didn't make it and why.

• Itransition: A strong candidate on paper, with named clients. But a December 4, 2024 report said Uzbekistan's competition committee approved its merger with Itransition Holdco Limited, a London parent. That looks like a group restructuring, not a sale, but it sits inside my window, so it is out under the rule.
• Softeq: Its case studies lean heavily toward hardware and connected devices. It fits our IoT ranking in this round better than an enterprise app list.
• Accenture, Infosys, EPAM and similar outsourcers: Real enterprise vendors, but they sell multiyear programs through a procurement motion that has little in common with hiring an app studio. Comparing them on this rubric would mislead both kinds of buyer.
• List authors: Several agencies that publish enterprise developer rankings place themselves on them. I left out any firm whose only appearance on enterprise lists was its own.

Two ranked firms need a note on mergers. Fueled announced its merger with the WordPress agency 10up on September 8, 2023, which is before my window. And hedgehog lab has been a buyer rather than a target: it acquired Netsells in 2023 and, according to its Wikipedia entry, Label Sessions in late 2025. An acquirer is still the same firm you hire, so both stay in, and I mention it because ownership affects who runs your project.

For the other eight, searches found no acquisition, merger or shutdown news from 2024 to 2026. Absence from search results isn't proof. Ask.

Six attributes, 0 to 2 points each, twelve maximum, all checked on September 30, 2026 from pages anyone can open.

• Named enterprise work: 2 for named enterprise clients with case studies on the company's own site; 1 when most case studies are anonymized or the named clients are small; 0 for none.
• SOC 2 or ISO 27001: 2 for a SOC 2 report or an ISO 27001 certification stated on the company's own site; 1 for vague compliance language or a certification logo whose standard isn't named; 0 for nothing.
• Named integration work: 2 for integration with an enterprise system of record or identity provider (Salesforce, SAP, Azure AD, Okta, an EHR) in a named project; 1 for integrations claimed as a service, listed as partnerships or shown in an unnamed case study; 0 for none found.
• Published pricing: 2 for app build figures on the company's own site; 1 for partial figures; 0 for none. Review directory ranges don't count.
• Public IP terms: 2 for an explicit source code and IP ownership statement on the company's own site; 1 for ownership language short of that; 0 for nothing on the pages checked.
• Years operating: 2 for a founding year or ten-plus years stated on the company's own site; 1 for a founding year from a third party or an indirect date; 0 for none found.

Ties break on named enterprise work, then years operating, then alphabetically. That's the whole rubric.

The security and integration attributes are what make this list different from our ranking of app development consulting firms in the same round. An enterprise app lives inside other systems. It signs people in through the company's identity provider and reads from a CRM or ERP. So the evidence that matters most is whether a firm has done that for someone you can name, and whether its security program has been audited.

What I excluded, and why.Projects delivered, clients served, apps launched and enterprise value created, because every one is the vendor's own claim. Headcount, because it doesn't tell you who works on your app. Awards, because most are paid or self-nominated. Clutch ratings and price ranges, because Clutch blocks automated reading and the numbers that reach me through snippets can't be checked at the source.

How to re-check it.Open each company's homepage, clients page and about page. Look for a founding year and a certification logo, then search the site for "SOC 2", "ISO 27001", "cost", "source code", "intellectual property", "Salesforce" and "SAP". Open two case studies and see whether the client is named. It takes about fifteen minutes per firm. If something changes after September 30, the score should change too, and I'd want to know.

ScienceSoft leads with 11 of 12, three points clear of three firms tied on 8. After that the table is settled mostly by tiebreaks.

Do the arithmetic. The ten totals add to 67, so the average is 6.7 of 12, about 56%. The leader discloses about 1.6x what the average firm does, and 2.75x what the three firms at the bottom do.

Now read the columns instead of the rows, because that's where the finding is. Pricing: nine of ten score zero. IP terms: seven of ten score zero. Named integration: only one firm scores 2. Named work and years: nearly everyone scores at least 1.

So the enterprise app market is open about who it has worked for and how long it has been around. It is fairly open about security, too: five of ten state an ISO 27001 certification or SOC 2 audit. It is quiet about what a build costs, who owns the code and which named system it connected to.

That last one surprised me. Every firm here says it integrates with enterprise systems. Only one showed me a named project where it did. The rest either anonymize the case ("a global claims management organization") or list partner logos. Anonymizing is often the client's requirement, so it isn't a sin, but it does mean you have to ask for a reference call to test the claim.

Every score above traces to a cell below. Where a cell quotes a figure, it's the company's own statement, and I say so.

Three cells deserve a note. Chetu's homepage says its engineering teams follow security frameworks aligned with ISO and SOC, but I couldn't find a named certificate on the pages I read. Aligning with a standard and being certified against it are different claims, so it scores 1.

Netguru shows a TÜV NORD certification logo on its site. TÜV NORD certifies against many standards, and the pages I read didn't say which one. If it's ISO 27001, Netguru moves to 7, level with ELEKS and TechAhead. One email would settle it.

And hedgehog lab shows a UKAS accredited management systems badge on its about page, but neither the badge nor the pages I read name the standard, so security scores 1, the same treatment as Netguru. Its founding year of 2007 comes from Wikipedia, not its own site, so years also scores 1. That drops it into a three-way tie on 4, and Fueled sits above it on the alphabetical tiebreak.

Each profile says who the firm suits, what I could verify and what I couldn't.None of this is a judgment of quality. I haven't worked with any of them, and I didn't audit their code.

Top ranked

1

ScienceSoft

the only firm that publishes prices and IP terms and a certificate

Score: 11 of 12. Suits: mid-size and large organizations, especially in healthcare and finance, that want a long-established vendor with published numbers.

Verifiable: its homepage says it was founded in 1989, lists a headquarters in McKinney, Texas, and states ISO 27001, ISO 27701 and ISO 9001 certification. Its enterprise mobile development page says a mobile app of average complexity costs $80,000 to $200,000 and that it has built mobile apps since 2005. Its offshore developer page says the code is in the client's sole ownership and gives an average rate of $50 to $90 an hour. Named clients include UNM Health Sciences Center and Atlas Credit.

Not verifiable: its Salesforce and Azure AD single sign-on case study describes the client only as an IT company, so integration scores 1. The price ranges are its own figures, not a market survey. The project and staff counts on its pages are its own claims, and I don't repeat them.

2

Chetu

big named clients and a plain IP promise

Score: 8 of 12. Suits: companies that want a large custom software vendor with experience across ERP and industry platforms.

Verifiable: its homepagenames clients including Johnson & Johnson, Siemens, Marriott and Petco, says it has 25+ years of experience and says clients receive the full source code and IP ownership of their custom solution. It lists a headquarters in Sunrise, Florida.

Not verifiable: security is described as frameworks aligned with ISO and SOC, with no named certificate, so it scores 1. Its SAP BusinessObjects timesheet case study describes the client only as a global claims management organization founded in 1918, so integration scores 1. No pricing on its own site.

3

Intellectsoft

the one named Salesforce mobile project

Score: 8 of 12. Suits: enterprises that need a mobile front end on top of a CRM or internal system, and brands that want named references.

Verifiable: its homepage shows ISO 27001 certification and a New York address. Its clients pagesays it was established in 2007 and links case studies for Eurostar, Harley-Davidson, Ernst & Young, Guinness, Jaguar Land Rover and Cirruspath. The Cirruspath project, Cirrus Insight Mobile for a product that integrates Salesforce with the email inbox, is the only named enterprise system integration I found across all ten firms.

Not verifiable: no pricing (an estimate form only) and no IP terms on the pages checked. Its enterprise development page shows ISO 9001 rather than 27001, so ask which certificate covers which office.

4

Mindbowser

healthcare focus, SOC 2 and an IP promise

Score: 8 of 12. Suits: health systems and digital health companies that need EHR integration and a vendor used to HIPAA work.

Verifiable: its homepage says it is SOC 2 Type II audited and promises complete IP ownership with zero licensing fees. It lists Epic SMART on FHIR work and names Okta, Auth0 and Salesforce among its tools. Its own 10th anniversary post, dated April 24, 2022, places its founding in 2012.

Not verifiable: most case studies describe the client rather than name it (a behavioral health network, a labor and delivery unit), so named work and integration score 1 each. No pricing.

ELEKS

three decades, ISO and SOC 2 both announced

Score: 7 of 12. Suits: European and global enterprises in logistics, energy and finance that want a long-established engineering partner.

Verifiable: its homepage says it was founded in 1991, lists a headquarters in Tallinn and names DPD, David Lloyd, Aramex and Drax. Its April 9, 2025 announcement says it transitioned to ISO 27001:2022 and completed a SOC 2 Type II audit, and mentions HITRUST.

Not verifiable:SAP and Salesforce appear as services, but I didn't read a named integration project, so that scores 1. No pricing and no IP terms on the pages checked.

The bottom half isn't worse at building. It publishes less, or its enterprise evidence sits somewhere I couldn't check.

6

TechAhead

SOC 2 and ISO, big-name clients

Score: 7 of 12. Suits: enterprises that want a US-contracted vendor with current security attestations and AI work.

Verifiable: its homepage states SOC 2 Type II certification dated July 2, 2025 and ISO 27001:2022, and names AXA, American Express, JLL and Audi. Its about page says it was founded in 2009 and gives an address in Agoura Hills, California.

Not verifiable:Microsoft and AWS partnerships are claimed, but I didn't find a named enterprise integration project, so that scores 1. No pricing or IP terms on its own pages. Its launch counts and review site rankings are its own claims.

Netguru

European product studio, big consumer names

Score: 6 of 12. Suits: enterprises that want a product-led studio for customer apps and commerce platforms.

Verifiable: its homepage names IKEA, Volkswagen and Merck, and its site data gives Poznań as its founding location. Its about page gives 2008 as its founding year and shows B Corp and TÜV NORD logos.

Not verifiable:the TÜV NORD certificate's standard isn't named on the pages I read, so security scores 1. No pricing on its own site; the hourly range that circulates comes from a review directory I couldn't read directly. No IP terms.

8

Fueled

the strongest named portfolio, the least paperwork

Score: 4 of 12. Suits: consumer brands, media groups and public institutions that want a design-led app and web partner.

Verifiable: its work page names case studies for WhiteHouse.gov, CLEAR, MGM Resorts, the Wall Street Journal, Six Flags and Warby Parker, among more than thirty. Its homepage calls it a WordPress VIP partner since 2011.

Not verifiable: no security attestation, pricing or IP terms on the pages checked, and no founding year of its own. Named integrations are commerce and messaging (Square for WooCommerce, MoEngage) rather than identity or ERP. A 4 here is the paperwork, not the portfolio.

9

hedgehog lab

UK consultancy with an unnamed certificate

Score: 4 of 12. Suits: UK financial services and public sector buyers that value a Crown Commercial Service supplier.

Verifiable: its homepage shows case studies for AJ Bell's dodl app, Deliveroo and Teachmate, shows Aviva and Santander logos and carries a Crown Commercial Service supplier badge. Its about page shows a B Corp link and a UKAS management systems badge.

Not verifiable: the badge does not name its standard, so security scores 1. No integration project, pricing or IP terms on the pages checked. Its founding year comes from Wikipedia, which also records its 2025 acquisition of Label Sessions.

Velvetech

two decades, partners listed

Score: 4 of 12. Suits: US mid-market firms in finance and healthcare that want CRM and identity integration.

Verifiable: its homepage says it has been in business for more than 20 years, lists offices in Florida and Chicago, names case studies for Tradespoon, Twinfold, Menhealth and H Capital, and lists Salesforce, Microsoft, Okta and Auth0 among its partners.

Not verifiable: the named clients are smaller companies, so named work scores 1. No security attestation, pricing or IP terms on the pages checked, and its about page returned a 404 on the day.

A SOC 2 report or ISO 27001 certificate tells you a vendor's security program was audited. It doesn't tell you your app will be secure.

Here's why I scored it anyway. Almost everything on a vendor site is written by the vendor. A certificate is issued by an outside auditor, and a SOC 2 report is written by one. That makes them the closest thing this market has to a public record, and it's the first question on nearly every enterprise security questionnaire.

The two aren't the same thing. ISO 27001 certifies a management system: the vendor has defined its security controls and an auditor checked it runs them. SOC 2 Type II is a report on whether specific controls operated over a period. Many security teams accept either. Some insist on one.

The wrong model is to treat a logo as a pass. The better model is to treat it like a driver's license: it confirms the person passed a test at some point and hasn't lost the right to drive. It doesn't tell you how they drive in the rain. You still check the scope (which offices, which services), the date and any exceptions noted by the auditor.

Scope is where buyers get caught. A certificate might cover one delivery center and not the team that will build your app. Intellectsoft's homepage shows ISO 27001 while its enterprise page shows ISO 9001; that's probably two pages built at different times, but it's exactly the kind of thing to ask about.

If your organization needs a partner to run its own review of an existing app, we offer a security audit service. To be clear, that's an assessment we perform, not a certification we hold.

The rank matters less than the fit. A 5 that matches your constraint beats an 11 that doesn't.

Decide your one non-negotiable first (a certificate, an integration, a budget ceiling, a time zone) and see who survives it. Then compare the survivors on everything else.

Two rows deserve a longer word.

The certificate-first buyer.If your security team won't look at a vendor without an ISO 27001 certificate or SOC 2 report, five firms here clear it: ScienceSoft, ELEKS, TechAhead, Intellectsoft and Mindbowser, with hedgehog lab worth an email to confirm its badge. That cut removes half the list in one step. It also removes us, which I'll come back to.

The integration-first buyer. If your app is mostly a mobile face on Salesforce, SAP or an EHR, the integration is the project. Ask each finalist for one named reference that did the same integration and a thirty-minute call with that client. Intellectsoft is the only firm that showed me a named one publicly, but the others may have references under NDA that they can share one to one.

Enterprise apps also come in two broad shapes, and they suit different vendors. Internal apps (field service, approvals, employee portals) live on your identity provider and your ERP. We describe how we build that shape on our portal development page. Customer-facing platforms sold to other businesses need multi-tenancy, billing and enterprise sign-on for your customers, which is the SaaS platform development work. Ask each finalist which shape their named references are.

A worked example makes the published numbers useful. This one is a scenario, not a client.

Consider a regional insurance company with about 400 field adjusters. It wants an iOS and Android app for claim inspections: sign-in through its Azure AD, photo capture that works offline, and claims written back to its existing claims system through an API. It has about $250,000 approved and wants a pilot in six months.

Step one is the budget sanity check against the only published app figures on this list. ScienceSoft puts an app of average complexity at $80,000 to $200,000 and high complexity business apps at $200,000 to $500,000. Offline sync plus a claims integration plus single sign-on is probably at the upper end of average or the low end of high. So $250,000 is about 1.25x the top of its average band and half the top of its high band. Plausible, not generous.

Step two is the rate check. ScienceSoft's offshore page gives an average of $50 to $90 an hour. At the midpoint, $70, $250,000 buys roughly 3,570 hours. Our own senior rate is $150 to $225 an hour; at the $187.50 midpoint the same budget buys about 1,330 hours, or roughly 0.37x the hours. That's the real trade in this market: more hours from a larger offshore team, or fewer hours from senior people. Neither is automatically better. It depends on how much of the work is judgment and how much is volume.

Step three is the security gate. The insurer's security team wants SOC 2 or ISO 27001. That cuts the pool to the five firms that state one, before anyone has been emailed.

Step four is the timeline. Six months is about 26 weeks. For comparison, our own published MVP process runs 4 to 10 weeks, and our internal apps with integrations sit well above that. A security review and an Azure AD app registration often take several weeks on the client side alone. Ask each finalist to show where the client's own approvals sit in their plan, because that's where enterprise pilots slip.

Step five is the part the table can't do: a reference call with a named client who did an Azure AD sign-in and an API write-back. Twenty minutes of that tells you more about delivery than any score I can publish.

The downside of this approach is that it rewards firms that publish. Some excellent enterprise builders publish very little because their clients insist on it. If your favorite got a zero somewhere, send the email. One reply can turn a zero into a two.

Several figures came up again and again while I built this list, and none of them should travel as fact.

The first group is vendor counters. Projects delivered, clients served, apps launched, engineers on staff, and in one case a figure for enterprise value created for a client. Every ranked firm with a counter publishes it about its own work, with no method and nobody outside checking. None is in the scores, and I don't repeat the figures.

The second is review directory data. Search summaries gave me hourly rates and project ranges for Netguru, Chetu, TechAhead and Fueled, all sourced to Clutch. Clutch blocks automated reading, so I couldn't confirm any of them at the source. They scored nothing. One firm also describes itself as ranked first globally in a Clutch awards list; that's the same problem.

The third is the enterprise app market size. Many ranking pages open with a projection of what the enterprise app market will be worth in some future year. Those figures come from paid market research reports with methods I can't see, and they vary widely between publishers. They don't help you choose a vendor anyway.

The fourth is the failure statistic. Enterprise software pitches love a figure for how many IT projects fail or run over. The versions that circulate trace back to studies with contested methods or to vendor marketing, and I've refused them in earlier articles. The honest version is shorter: projects slip, mostly on scope and approvals, and your contract should say what happens when they do.

And one of our own. One of our case studies carries headline figures that I can't source to anything outside the page, so I don't use them here either. The rule applies to us first.

Once you have two or three proposals, these are the lines I'd look for first.

• No clause assigning code and IP to you: Seven of ten ranked firms publish nothing on IP. Get a written assignment covering source code, designs, infrastructure scripts and documentation, and note any reused vendor libraries.
• A certificate that doesn't cover the delivery team: Ask for the ISO certificate or SOC 2 report and check that its scope includes the office and services that will build your app.
• Integration listed as a line item with no discovery: Identity and system-of-record integrations are where estimates break. A proposal that prices them before anyone has seen your API documentation is guessing.
• Cloud accounts in the vendor's name: Your cloud accounts, app store developer accounts and repositories should be in your company's name, with the vendor added as a collaborator.
• No named people: Enterprise proposals often show a senior team at the pitch. Ask who writes the code, by name, and what share of their time you get.
• No post-launch warranty: Ask what is fixed free after launch and for how long, and what support costs after that.
• Counters on slide one: Projects delivered and clients served are marketing. Ask for one named reference with the same integration instead.
• A budget that only covers the build: Hosting, device management, app store accounts, monitoring, penetration tests and OS updates keep costing after launch.

None of these is exotic. They're the same questions a good procurement team asks of any vendor. The difference with apps is that the code keeps running on thousands of devices after the vendor leaves, so the handover terms matter more than the launch date.

Here is what I chased and couldn't establish, so you can weigh the ranking accordingly.

• Delivery quality: No neutral benchmark of enterprise app vendors exists, and I didn't audit anyone's code. The ranking measures disclosure, not delivery.
• Certificates themselves: I read what each vendor states about ISO 27001 and SOC 2. I didn't see the certificates or reports, which are usually shared under NDA.
• Unnamed case studies: Anonymized work may well be real and enterprise grade. It scores lower only because a buyer can't check it from outside.
• Clutch and review data: Clutch blocks automated reads. No rating, review count or price range from it is scored.
• Third-party dates: One founding year comes from Wikipedia rather than the firm's own site and scores accordingly.
• Acquisition status: Searches found no 2024 to 2026 acquisition of the ten. That isn't proof there were none.
• Contract terms: IP and warranty terms usually live in an agreement nobody publishes. Absence on a website isn't absence in a contract.

None of this makes the list less useful. It makes it a shortlist you can audit, which is the most a public ranking can fairly claim to be.

Frenchy Digital is my company. That's a conflict of interest, and it's why this pick sits outside the scored table and is labelled as mine.

So let me score it the same way first. Named enterprise work: 2, for three named case studies I'll describe below. SOC 2 or ISO 27001: 0. We don't hold a SOC 2 report, an ISO 27001 certificate or HITRUST, and I won't pretend a signed BAA is the same thing. Named integration: 1. Our service pages list single sign-on, SAML and CRM integrations such as Salesforce, but none of our published case studies shows a named SSO or ERP integration, so we get the same 1 as ELEKS and TechAhead. Pricing: 2, because our service pages publish price bands. IP terms: 2, because full source code and IP ownership transfer is stated. Years operating: 2, since 2016 in France and as a US company since 2019.

That's 9 of 12. It would place us second of eleven, behind ScienceSoft's 11 and one point ahead of the three firms on 8. Not first. The two points we lose are the certificate, and that's the attribute enterprise security teams ask about first. I'd rather print that than tune the rubric.

So why is it still my pick?Because the rubric measures disclosure across the whole market, and a particular buyer cares about a particular subset. If your security team can review a vendor without a certificate, and what you want is senior people on the build, a price before the first call and ownership of everything at the end, the attributes that matter most to you are price and IP. That's where seven to nine of ten ranked firms score zero.

Concretely: we're a senior-led, Black-owned app and AI agency in Los Angeles. Our portal tiers run $35,000 to $60,000, $60,000 to $100,000 and $100,000 to $150,000 and up. Our SaaS platform tiers run $80,000 to $150,000, $150,000 to $300,000 and $300,000 to $500,000 and up. A discovery and workflow audit runs $9,000 to $22,000 over 2 to 4 weeks. Senior time is $150 to $225 an hour, retainers run $2,500 to $9,500 a month, and you get a fixed-price phased proposal within 5 business days, a 30-day post-launch warranty, full source code and IP ownership, and we sign BAAs where health data is involved.

Run the same arithmetic I ran for the others. Our middle portal tier tops out at half of ScienceSoft's published $200,000 ceiling for an average app. Our first SaaS tier starts exactly at its $80,000 floor. That's the honest positioning: senior rates, so fewer hours per dollar, and published bands that sit inside the range the largest vendor on this list publishes.

Now the proof. For SnapFit, working with the Los Angeles studio Fairfax Training, we built a corporate fitness platform for Snapchat employees on iOS, Android and a web dashboard, with React Native, Node.js and Firebase, over about eight months from discovery to launch. For the NDA member platform we ran a documented off-boarding from the previous agency (ownership transfer, credential rotation, a security check), rebuilt the public site on Webflow and built a member platform on Supabase with Stripe billing tied to membership state and a Discourse community integration. That program has run since 2024. And for ScoreBiz 360 we built a merchant credit scoring web platform for a fintech founder. That case study carries headline figures I can't source, so I won't repeat them.

You can get from this page to a defensible shortlist in about a week.Here's the order I'd do it in.

1. 1.Ask your security team today whether a SOC 2 report or ISO 27001 certificate is mandatory, and which one. Use the answer and the buyer-type table to cut the list to three firms.
2. 2.Email the three the same six requests: the certificate or report and its scope, the named people who will build the app, one named reference with the integration you need, a fixed-price phased proposal, the IP assignment clause from their standard agreement, and what their post-launch warranty covers.
3. 3.Book the reference calls before you read the proposals. Ask each reference one question: what happened the first time something went wrong, and how long did it take to fix?

Whoever answers all six requests cleanly, and whose reference answers that last question without hesitating, is probably your vendor. Time to send the emails.
