The Proof of Concept
Stop pitching a slide.
Start showing software.
In six weeks, we build working software that proves the hardest part of your idea — and hand you a costed plan for the rest.

The problem
Investors have seen the deck before. They want to see it working.
The gap between an idea and real software is where most early-stage projects stall. Agencies quote six figures before anyone’s proven it’s buildable. Offshore is a quality gamble. Either way, you’re betting big with no proof.
There’s a better first step.
The same idea gets quoted at $25k or $90k — depending only on scope.
The Proof of Concept fixes the scope, the price, and the one thing you’re proving, before the big build begins.
What you get
Real software you can put in front of anyone.
Three deliverables
Everything you need for the next conversation.
01
A working demo
Not a mockup. Live software that solves the hardest technical challenge in your idea — the part everyone’s unsure about.
02
A costed build plan
A scoped, priced roadmap to the full product. When an investor asks “what does it cost to finish?”, you have a real answer.
03
Certainty
Fixed price, fixed timeline, one clear thing we’re proving. No open-ended hours. No scope creep. No surprises.
Why us
You work directly with the engineers writing your code.
Most agencies sell you a star team, then swap in whoever’s free. We’re the opposite. You work with senior engineers who’ve shipped real systems at Automattic, ThoughtWorks and Block — where the job meant processing billions of events a day.
At the earliest stage, backers are betting on whether the hard thing can be done, and by whom. Credible engineers make that an easy yes.
We’re a small team, superpowered by AI, moving at a pace that wasn’t possible two years ago. That’s what proves in six weeks what used to take a quarter.
How it works
Two three-week sprints. Start with one.
Sprint 1 · 3 weeks
Prove it
Working software that proves your hardest technical challenge is solvable. Something real and running.

Sprint 2 · 3 weeks
Make it demo-ready
We polish the proof into a demo you’d show investors, and deliver your costed plan for the full build.

The full Proof of Concept — 6 weeks
Both sprints. Six weeks reliably produces a demo worth raising on, and answers the technical questions that matter.

The full build
The proof replaces guesswork with a real number.
Where most builds land
Starting band
Focused MVP
One core workflow, polished for real users.
$30k – $80k
Standard SaaS MVP
Multiple workflows, integrations, a real backend.
$80k – $180k
Complex MVP
Heavy data, AI, real-time, or compliance-sensitive.
$180k – $300k+
Starting bands, not quotes. Your Proof of Concept produces a precise, scoped figure for your build — so you’re never guessing, and neither are your investors.
Is this you?
Built for founders with one hard question.
For you if…
Your idea lives or dies on one hard technical question, and you need to prove it works before committing serious money — or before anyone will back you.
Not if…
You already know it’s buildable and just want the cheapest build. We’re not the cheapest — we’re who you call when getting it right, and proving it, matters.
Questions
The things founders ask first.
What do I own at the end?
Everything. The code, the demo, the plan. No lock-in, no licensing games.
Can I just do the first sprint?
Yes — that’s why we split it. Start with Sprint 1 for $12,750, see real software, then decide. Most do both, but you’re never locked in.
Do you build the full product afterwards?
Usually — most clients come back once they’ve raised, since by then we know the product better than anyone. But you’re free to take the proof anywhere.
Can you really do this in six weeks?
Yes — senior engineers with modern AI tooling move dramatically faster than even two years ago. The fixed timeline forces focus on what matters most.
Why should I trust the result?
Because you work directly with the engineers building it, and the proof is working software you can use yourself — not a report asking you to take our word for it.
