MVP Development for Non-Technical Founders

This isn't "app development." This is a compressed founder engagement where I validate the business case before writing code, then ship something real in weeks.

What Makes This Different

Every engagement begins with questions a dev shop won't ask

Who is the customer?

Not a persona, not a demographic. A real person with a real problem who will actually pay for a solution.

What's the unit economics?

What does it cost to acquire a customer? What's the lifetime value? Does this business actually pencil out?

What's your distribution?

How will customers find you? If you can't answer this before building, we need to figure it out together.

What happens if this works?

What's the operational model? Can you actually deliver at scale? I think about this before you have to.

What's the simplest version?

What's the smallest thing that tests whether this is real? That's what I build first.

Should this even be built?

Sometimes the answer is no, or not yet, or not this way. I'll tell you honestly.

The Process

From idea to production in weeks

01

Validate

Before I write a line of code, I pressure-test the business case. Who's the customer? Why will they pay? What's the riskiest assumption? I identify the smallest experiment that tests whether your idea has legs.

02

Architect

I design for what you need now with a clear path to what you'll need later. No over-engineering, no technical debt traps. Just a foundation that can scale if the idea works.

03

Build

Production-ready software, shipped in weeks. Not a prototype, not a demo. Real code that can acquire real users and generate real feedback.

04

Launch

I don't disappear after handoff. I help you get in front of users, collect feedback, and iterate. The goal is validation. Delivery is the easy half.

Ideal For

This service is built for

  • First-time founders with domain expertise and an idea they've been thinking about
  • Entrepreneurs who need a technical partner for the 0-to-1 phase
  • Business owners validating a new product line or service
  • Anyone who wants honest feedback before investing months in development
Not For

This probably isn't right if

  • Projects where the scope is already locked and you just need execution
  • Clients looking for the cheapest option
  • Ideas that haven't been validated with any customer research
  • Anyone who wants a vendor, not a partner
Pricing

What an MVP costs, and why there's no rate card

Most MVPs land between $15,000 to $50,000+. That range is wide because it has to be, and I'd rather explain why than pretend otherwise.

Website work here is priced per page, published down to the dollar, because a page is a countable thing and a privacy policy is always about the same amount of work.

Software has no equivalent unit. A screen can take a day or a month depending on what happens behind it. Two products with identical page counts can differ by a factor of five, and any per-screen number I published would be wrong in both directions at once.

What moves the number, in rough order of impact:

  • Platform A web app is one build. Native iOS or Android means app store review, device testing, and release cycles. Both platforms roughly doubles it.
  • Integrations Payments, auth, third-party APIs, anything with a sandbox and a certification step. Each one carries failure modes that have to be handled.
  • Data A form that saves a record is not a system that reconciles state across users. Multi-user, real-time, and financial data all raise the floor.
  • Compliance Health, financial, or education data brings requirements that are not optional and not quick.
  • Clarity The cheapest projects are the ones where the founder can say precisely what they need to learn. The expensive ones discover that halfway through.

Minimum valuable, not minimum viable

The scoping question is what actually controls your cost, so it's worth being precise about it. The standard advice says build the smallest thing that works. I'd put it differently: build the smallest thing that's complete enough to validate.

Those come apart more often than people expect. A product stripped past the point of being genuinely useful still launches, still gets users, and still produces data. The data is just noise, because nobody was ever going to pay for that version. You spent the money and learned nothing.

I wrote about where that line sits and how to tell when you're on the wrong side of it.

How the number gets set

Discovery comes first, and it's a real conversation about the business rather than a requirements form. What are you trying to learn? What has to be true for this to work? Who is it for, and what do they do today instead?

That conversation usually cuts scope, because most of what founders arrive wanting is not needed to answer the question they actually have.

You get a fixed price before any work starts. Not an hourly rate, which pays me for taking longer.

"The goal isn't to build what you ask for. It's to build what actually validates your hypothesis, and know the difference."
MVP Questions

Frequently Asked Questions

An MVP (Minimum Viable Product) is the smallest version of your product that can test your core hypothesis with real users. It's not a prototype or mockup. It's a working product that solves a real problem, just scoped to the essentials.

I identify your riskiest assumption, the thing that would kill the business if wrong, and build the smallest thing that tests it. Everything else waits for validation. This keeps scope tight and gets you to market faster.

I'll still pressure-test your assumptions. Often founders know their domain deeply but haven't thought through the technical or operational implications. That said, if you've done the validation work already, we'll move faster through that phase.

Not for the 0-to-1 phase. I serve as your technical partner through validation and initial launch. If the product takes off, I can help you hire and onboard your own technical team.

I pick the right tool for the job, not my favorite stack. That said, I often use Python/Flask or Node for backends, React or Astro for frontends, and modern cloud platforms for infrastructure. I optimize for speed to market and maintainability.

Most land between $15,000 and $50,000+. The range is wide because software has no equivalent of a page count: platform, integrations, data complexity, and compliance each move it substantially. A web app is one build; native iOS and Android roughly doubles it. You get a fixed price after discovery, before any work starts.

Because a page is a countable unit and a screen isn't. A privacy policy is always about the same work, so per-page pricing is honest. Two apps with identical screen counts can differ fivefold depending on what happens behind those screens. Any per-screen number would be wrong in both directions at once.

Viable means it works. Valuable means it's complete enough that someone would actually use and pay for it. A product stripped past that point still launches and still produces data, but the data is noise, because nobody was going to buy that version regardless. Scoping to valuable rather than viable is what makes the spend worth anything.

That's actually a success. You've learned something important for a fraction of what it would have cost to build the full product. I help you interpret the results and decide whether to pivot, iterate, or move on.
