The 4-Week AI Sprint: From Idea to Working Prototype, Step by Step

The most expensive words in AI are "let's build the whole thing." The cheapest are "let's find out in four weeks." This is the exact structure of our AI Sprint — the smallest honest way to answer the question every founder actually has: will this work on my data, for my users, at a cost that makes sense?

Why small-first beats big-vision

AI projects carry a kind of uncertainty normal software doesn't: nobody — including us — knows exactly how well a model will perform on your specific data until it's tried. Pretending otherwise is how six-month contracts end in demos that impress nobody. A sprint converts that uncertainty into evidence, at fixed cost, in weeks.

Week 0: the scoping call

Before anything is signed: a free 20-minute call with a senior engineer — not a salesperson. We need three things from you: the problem in your own words, access to a sample of the real data, and a decision-maker who'll look at weekly demos. If the idea doesn't need AI at all, this is where we say so and point you at something cheaper.

Week 1: the thin slice

We take the narrowest complete path through the problem — one document type, one workflow, one conversation — and make it work end to end on your actual data. Ugly, but real. At the same time we start the eval set: the first fifty real questions or cases, with what a correct result looks like. Friday: you see it run.

Week 2: the working core

The slice becomes a system: proper retrieval over your knowledge, guardrails for the obvious failure modes, the first accuracy numbers from the growing eval suite. This is the week expectations meet reality — sometimes the model exceeds them, sometimes we adjust the approach. Either way you're watching it happen, not reading about it later.

Week 3: hardening

Edge cases, error handling, the integration that matters most (your CRM, your helpdesk, your telephony), and cost measurement: what does one task actually cost in model calls? We tune that number down — caching, routing simple cases to smaller models — because unit economics decide whether this scales.

Week 4: the decision packet

You end the sprint with four things: a working prototype you own outright; eval results — real accuracy numbers on real cases, not adjectives; a cost model for running it at your volume; and a roadmap with a fixed quote for the production build, if the evidence says go.

Sometimes the answer is no — that's a win

A sprint that ends in "the accuracy isn't there yet" or "the economics don't close" for the price of a prototype is the cheapest good news in software. You've spent a fraction of a failed build to avoid the whole failed build — and you keep the eval suite and everything we learned.

Have an idea that deserves four honest weeks? Ask the studio live or book the 20-minute scoping call — week 0 is free either way.
