All case studies

A good fit if

  • You're a pre-seed or seed founder with an AI product idea and you need real-user validation fast — not a 6-month build.
  • You have a technical co-founder or eng team but they're underwater on another project and you need an MVP out the door now.
  • You've been burned by agencies that ship demo-ware you can't scale past 10 users.

Not a fit if

  • You need a production system for thousands of users (that’s the Sprint)
  • You want a slide-deck prototype, not working software
  • You can’t give feedback during the 3 weeks
Pricing

What moves the price

  • Sprint length (3 weeks standard; 4 weeks with payment + landing)
  • Whether payment collection and billing are in scope
  • Number of third-party integrations (auth providers, email, Stripe)
  • Design complexity — custom design system vs Tailwind + shadcn defaults

Standard 3-week sprint runs $15–22K. Extended (4 weeks with payment, landing page, analytics) runs $22–30K. If you need an AI Product Sprint instead ($30–60K, 4–6 weeks), that's the next tier — more architecture, more polish, more production-grade. Fixed-price per sprint, milestone-based payment.

Included
  • Front end, back end and LLM integration
  • Real auth, database and payments if needed
  • Analytics to see what users do
  • Hosted demo URL for investors
  • 30 days of bug fixes
How it works

Three weeks from idea to live product.

  1. Week 0

    Scope lock

    1-hour call. I write a 1-pager: the single user journey we're validating, what we're explicitly NOT building, the success metric for the validation. Free.

  2. Week 1

    Core flow

    Auth, database schema, primary user journey end-to-end. Ugly but functional. Deployed to a staging URL by Friday.

  3. Week 2

    AI layer + polish

    LLM integration, prompts, basic evals, UX polish. The design background shows up here — your MVP doesn't look vibe-coded.

  4. Week 3

    Launch

    Analytics, payment (if needed), landing page, launch. Hand off the repo.

What you don't risk
  • Fixed price, agreed up front
  • Code in your GitHub, not mine
  • Built to grow into a Sprint
  • No hourly meter

Everything that's included

  • A working AI product with real authentication, real database, real users — not a Streamlit demo.
  • Full front-end (Next.js or React) + back-end (FastAPI or Node) + LLM integration.
  • Payment collection wired in (Stripe) if you're validating pricing.
  • Basic analytics (Posthog or GA4) so you can see what users actually do.
  • A hosted demo URL your investors and design partners can click through.
  • Source code in your GitHub org — not mine — so you own everything from day one.
  • 30 days of bug-fix support after launch.

What I build with

Default stack: Next.js + Supabase + LangGraph + Claude. Boring, fast, and the code can evolve into your v1 without a rewrite. I avoid exotic frameworks in MVPs — every day spent learning a new tool is a day you're not learning from users. The AI-assisted development workflow (Cursor + Claude) is what makes the 3-week timeline real; without it, this is a 10-week build.

FAQ

Common questions.

Real questions from scoping calls. If yours isn't here, ask it on a free 30-minute call.

One user journey end-to-end with auth + LLM integration + polished UX, hosted on a staging URL, source code in your repo. With the 4-week extension: add payment, analytics, landing page. I always under-promise on scope and ship what's in the one-pager, not what creeps in over Slack.

Most founders don't at MVP stage — that's fine. For RAG products, I seed with public data (docs, blogs) or use synthetic data we generate together. For agent products, we focus on workflow logic first; data quality becomes a v1.1 problem.

Yes, from day one. Repo lives in your GitHub org, not mine. Stack is standard and popular, so any full-stack engineer can take it over.

30 days of bug-fix support is included. After that you can either hire a full-time engineer (I'm happy to help interview) or convert to an Agentic Product Retainer for the next phase — most founders pick one or the other after real-user feedback comes in.

Vibe coding (Karpathy 2025) = AI-assisted development where you describe what you want and Claude/Cursor write the code. The technique closed the 'I'm not technical enough to ship' gap for designer-PMs in 2026. My MVPs ship polished because the design + product judgment is the bottleneck, not typing speed.

Have an idea? Let’s ship it in three weeks.
