AI MVP prototype builder
AI MVP prototype builder is the workflow that compresses the 'should we even build this' phase from months to days: a clickable prototype, a functional MVP and a written build roadmap. Engine Labs ships this as the Founder Engine.
What is AI MVP prototype builder?
AI MVP prototype builder takes an idea written in plain English, a 30-minute scoping workshop and the smallest set of features that proves the idea, and returns a clickable prototype, an MVP with one core feature and a lightweight backend, and a build roadmap for the next three milestones. Enough to test with first users or show in an investor meeting.
Who is it for?
Solo founders and pre-seed teams who need to test the idea before they quit, raise or hire. Anyone trying to compress the early product phase without paying for a fractional CTO and a product designer for six weeks.
What does it replace?
A fractional CTO plus a product designer for the first sprint of a startup.
What inputs does it need?
- Your idea, written in plain English (we will help you tighten it).
- Any existing brand, design or domain assets.
- Whatever you have already built or sketched.
- Who you are building for and what they currently do instead.
What does the system output?
- A clickable prototype (5–10 screens) covering the core flow.
- A working MVP with auth, one core feature and a lightweight backend.
- A written build roadmap covering the next three milestones.
How much does it cost?
The Founder Engine price band runs from A$750 to A$8,500 AUD, GST exclusive unless stated, scoped in the Control Centre. See the full pricing schedule for tiered detail.
What tools can it integrate with?
Figma, Framer, Webflow, Bubble, Lovable, v0, Cursor, Supabase, Firebase, Vercel, Stripe, Postmark, Resend, Clerk, Auth0.
What should not be automated?
- App store submission or compliance review, production-scale infrastructure, DevOps or load testing.
- Funding strategy, investor introductions or fundraising support, and outcome guarantees on traction or product-market fit.

How Engine Labs builds it
Brief, scope, build, acceptance, handover. Two to six weeks depending on tier. Starts with a paid 30-minute scoping workshop, credited against the final fee if you proceed. The handover pack includes repo access, deployment notes, prompt and automation documentation, and known limitations. The full six-step Build → Run loop is on the methodology page.
FAQ
Questions about AI MVP prototype builder.
No. Engine Labs builds what is in the scoped Statement Of Work; if the build reveals that the idea should change, that is a Change Request, not a unilateral pivot. You own every product decision.
The Founder Engine price band runs from A$750 to A$8,500 AUD, GST exclusive unless stated. Basic is a clickable prototype only; Standard is a functional MVP with one core feature and a lightweight backend; Premium is a controlled multi-feature MVP with integrations, auth, payments and a documented roadmap.
Two to six weeks calendar time, tier-dependent. The Control Centre will give you a band based on the brief.
Optionally. After handover you choose whether to opt into a Support plan or to take the build to your own developer with the handover pack — the pack is designed for either path.
