MVP development for AI and fintech startups

An MVP is the smallest version of your product that real people can use, built to prove they want it before you pay for the rest. I’m Mo Tawfik Khalifa, chief product officer and forward deployed engineer at Instruxi, and I build MVPs myself with AI at every step: the scope, the design, the code and the launch, from one senior person.

That matters because most of an app budget goes after the first screen works. On Clutch, the most common app development project costs $10,000 to $49,999, the average is $90,780.11 and the typical timeline is about 11 months (page updated 21 September 2026). An MVP is how you find out whether to spend that.

Worried it ends half-built?

These are the worries founders write down before they hire anyone, in their own words, and what I do about each one.

What does an MVP development company actually do?

An MVP development company turns your idea into the smallest product that proves people want it, and ships it to real users. The good ones also decide what to leave out, and build the parts that carry risk, sign-in, data and money, properly from day one.

In practice that is five jobs:

1. Scope. One job, for one kind of user, and one number that says it worked.
2. Design the flow. The screens for that one job, and nothing else.
3. Build. A working version on a test link people can press and break.
4. Harden. Data rules, secrets, payments, real phones, a backup and a way back.
5. Launch and learn. Real users, the number counted, and what to build next.

At an agency those jobs pass down a chain: sales scopes it, a project manager writes tickets, a designer draws it, developers build it, QA tests it. Every handover loses a bit of why. I make the product calls and write the code, so whoever decides what to cut knows what each feature costs to build. That is the forward deployed engineer way of working, and when the job is bigger than one MVP it becomes fractional CPO work.

What is an MVP, and what is it not?

Eric Ries, who made the term popular, defined it in 2009 as the version that collects “the maximum amount of validated learning about customers with the least effort” (Startup Lessons Learned). The test is learning, not features.

• An MVP is one job done end to end, used by real people on their own phones, with the one number counted.
• It is not every feature, half built. Ten rough features teach less than one finished one.
• It is not a demo that breaks when a second person signs in. If strangers use it, their data is safe on day one.
• It is not a store app by default. I start most MVPs in the browser, as I explain in what an app costs to build.

What do you get, and how fast?

With AI doing the typing, the first version is quick and the hardening is the real work. When I built Laqtaa alone with AI, I wrote a 780-line brief first, and on the first day six milestones were built and deployed in 53 minutes. A couple of hours later the next commit read “resolve all critical runtime bugs”. Over five weeks that became 188 commits, 93 of them fixes, and then about 100 wedding guests used it on the day and nothing broke.

So this is the shape I plan to:

• Week 1. A one-page scope with its no list, and the one job working on a test link.
• The weeks after. Hardening and testing on real phones, then launch. For a focused MVP like Laqtaa that was five weeks.
• Anything that moves money or checks identity takes longer to harden. On a fractional engagement I plan a prototype on your real data in month one and hardening in months two and three.
• What you keep. The code in your own repository, the developer and hosting accounts in your name, a note on how it runs, and a named owner on your side.

Tick what you want in your MVP below. The board sorts each feature into what goes on the test link in week one, what has to be ready before launch, and what waits. Then print it as a one-page scope to send to whoever quotes it, me or anyone else.

Which stack do you build an MVP on?

The boring one that the next developer can read. My defaults, and why:

• The browser first. A web app opens from a link, skips store fees and review, and can still use the camera. Laqtaa’s guests scan a QR code and shoot from the browser: wedding photo sharing with a QR code.
• Supabase and Vercel. Postgres with sign-in, storage and Row Level Security, and hosting that deploys on every push. Laqtaa runs on both for about $46 a month: $20 for Vercel Pro, $25 for Supabase Pro and about $1 for the domain. I have also moved apps from Firebase to Supabase without logging anyone out.
• A mainstream TypeScript web framework. Popular enough that the developer you hire after me has used it before.
• Native apps when the product needs them. The credential passport I built for clinicians runs on iOS, Android and the web. For loyalty, a card in Apple or Google Wallet often replaces an app: see Wallet stamp cards.
• AI features on a model API, with a monthly spend cap set before launch, and a check outside the model before anything acts.

How do you keep an MVP secure from day one?

By treating sign-in, data and money as day-one work, because they are what an MVP gets wrong first. The list I run on every build:

1. Row Level Security on every table, so one user can’t read another’s records. My Supabase security checklist has the SQL.
2. Secret keys on the server only, never in the JavaScript every visitor downloads.
3. Roles checked on the server, never by a field the user can edit.
4. Payment webhooks verified and handled once, so a fake or repeated message never marks an order paid. The code is in vibe coding: how to ship it safely.
5. Upload limits and private storage.
6. A backup you have restored once, and the last release ready to roll back to.
7. A guard on the coding agent. The AI that writes the code has a shell and your keys, and it can delete your database. I lead product for GVNR at Instruxi, a free and source-available guard that decides allow, deny or ask a person before an agent acts, with a hash-chained record of every decision. It works with any AI agent, including Claude Code, Cursor, Codex, Gemini CLI and any MCP client.

The full pre-launch pass is my vibe coding security checklist: 13 checks a founder can run in an afternoon.

How much does MVP development cost?

It depends on how much the MVP does, how many platforms it runs on, and who builds it at what rate. I don’t publish my prices. These are market numbers, from the source.

I price each build after a first call, from the scope you print above, the platforms and how much of it touches money or personal data.

How do you choose an MVP development company? Eight red flags

1. A price before a written scope. Without one page that says what is in and what is out, two quotes can’t be compared.
2. Nothing live you can open. Ask for products real people use today.
3. Every feature in version one. If they never say no, the MVP becomes the full product at MVP speed.
4. Security “in phase two”. Data rules and secrets are day-one work. Retrofitting them costs more.
5. The code and accounts in their name. Your repository, your developer accounts, your domain, from day one.
6. The person who sold it never builds it. Ask who writes the code and who decides what gets cut.
7. “AI makes it nearly free.” AI makes the first version faster. In one trial, experienced developers on mature code took 19% longer with AI. The evidence is in my app cost note.
8. No plan for month two. Ask who fixes bugs and updates it after launch, and what they hand over.

What have I built that looks like your MVP?

I built all of these, but most of my work at Instruxi is under NDA, so I can’t name the clients. These are the builds I have written up, with the proof you can open.

How long does it take to build an MVP?

With AI in the loop, a first version can be on a test link in the first week. Hardening takes longer: Laqtaa took five weeks and 188 commits before about 100 wedding guests used it. Anything that moves money or checks identity needs more time for hardening.

Should my MVP be a web app or a mobile app?

Start in the browser unless the product needs the phone’s hardware or the app stores. A web app opens from a link, skips store fees and review, and can still use the phone’s camera. Build store apps once the web version proves demand.

Can I build my MVP myself with AI?

You can build a prototype yourself with AI. Before it takes money, stores other people’s data or opens to strangers, someone who reads code needs to check secrets, sign-in, data rules, payments and load. My note on vibe coding has the order I work in.

Do I own the code?

You should, from day one. The code lives in your repository and the developer, hosting and store accounts are in your name. I work that way on every build.

Do you work with UK and US startups, and remotely?

Yes. I work with UK teams and teams elsewhere, remote or on site. I have led teams across countries, on site and remote, for more than eleven years.

1. 30-minute call. Your goal, your users, what is stuck.
2. A written plan in 48 hours. What to build first, how long it takes, the risks.
3. Start, or not. Use the plan with your team or with me. I reply to every email within one working day.
