The decision you’re actually making
You’re about to commit six figures to a guess.
The number in your build quote came from two calls and no specification. Everyone involved knows that. Drag the slider to your budget and see what the guess is costing you.

$8,000 now, against a $20,000 miss you cannot yet rule out.
Two weeks costs less than the error it prevents.
Ten working days. Six deliverables you keep whatever you decide.
What lands in two weeks
Six things land on day ten. Only one is about hiring us.
Deliverable 02
Know how it gets built, and what it plugs into
Architecture, the integrations this actually needs, and a data model sketch. These are the decisions that get expensive to reverse, so they get made now and written down.
Deliverable 03
A scope document written from findings, not a sales call
Deliverables, acceptance criteria, and an explicit list of what is not included. Ready to sign, with anyone.
Deliverable 04
A price you can check the working on
Built by the engineer who would do the work, with every assumption listed beside the number. When a cheaper quote arrives, you can see exactly which assumption it dropped.
Deliverable 05
Three budgets, so the answer is never just no
What fits a smaller number, what fits the middle, what the full thing costs. The conversation becomes which trade-off you want, instead of one take-it-or-leave-it figure.
Deliverable 06
Vet anyone who bids on this, including us
How to read an agency, a team, or a contractor. What building software actually involves in 2026, where AI-assisted development genuinely works, and where it quietly stops working. Written to be useful even if you take it somewhere else.
What the interactive spec is, and what it isn’t
This is not a workshop and not a strategy deck. But clients hear “clickable” and picture working software, so it is worth settling what it is before day one.
It is
- A specification you can click through, at full visual fidelity
- Every screen, every state, every flow, decided
- Something any developer can build from as the source of truth
- Yours to keep, use, and take anywhere
It is not
- Working software, and not a head start on the build
- Connected to a database, an API, or a real account
- A percentage of the engineering already complete
- Something that shortens the build by itself
A sample of what you get
Pick a budget. See what you give up.
Every sprint ends with your build priced at three levels. Below is a worked example for an order-intake system.

Nothing. This level is the whole system.
Example only. Yours is built from your actual workflow in week two.
How the two weeks run
Ten working days. About five hours of your time.
Two working sessions, one review call, one handover. Nothing to prepare. We pull the workflow out of your team’s head on the calls.
The four days you are involved
Day 1 to day 10
- Days 1–2
Working sessions You are in this
Two calls with you and whoever knows how the work gets done today. We leave with the problem sized, the constraints named, and the success measure written in your words.
- Days 3–6
Spec and architecture
We design the product and the system underneath it. You get a mid-week look so nothing lands as a surprise on day ten.
- Day 7
Review call You are in this
You walk the spec and tell us where it’s wrong. Corrections go in before anything is finalized.
- Days 8–9
Estimate and scope levels
The engineer who would build it produces the hours. We assemble the SOW and the three budget options.
- Day 10
Handover You are in this
All six deliverables, walked live and then sent. From there it’s your call, with everything you need to make it.
The terms
$8,000
Fixed. Two weeks. No change orders, no hourly overage.
You keep everything, whatever you decide. Spec, architecture, SOW, estimate, vetting guide. If we’re not the right team, you leave with the whole package and can hand it to anyone.
GuaranteeHand it to any developer. If they can’t build from it, we fix it free. The spec is written to be read by someone who has never spoken to us. If the team you pick says it isn’t enough to quote and build from, we revise until it is, and refund the $8,000 if we can’t.
$4,000 comes off your first invoice if you start the build with us within 90 days. Net cost of the sprint: $4,000.
Already decided to build? Start here anyway. You do not need a separate step first. The sprint becomes the opening two weeks of the engagement, $4,000 comes off your first build invoice, and you make one decision instead of two. Those two weeks produce the spec and the build kickoff, not two weeks of building — the specification is the work.
GuaranteeDelivered in ten working days or $1,000 comes off. The guarantee covers our timeline, not your opinion of the findings. A sprint that could only conclude “yes, build it” would be worth nothing to you.
“Don’t build this” is a legitimate outcome. If the honest finding is that the project isn’t viable yet, that’s what you’ll get, in two weeks instead of four months.
In every sprint
Three additions, at no extra cost.
Recorded spec walkthrough
A narrated tour of the finished spec, so you can bring a board, a team, or an investor up to speed without scheduling anything.
30 days of questions
A month of async access after handover. Ask about the architecture, a quote you got elsewhere, or a decision you’re weighing. No clock running.
Second revision pass
One more round on the spec after you’ve lived with it a week. Things look different once you’ve shown them to someone else.
If we’re not the right team, you should know in two weeks.
Most agencies write a proposal for free and then need you to say yes, because the proposal was the investment. That pressure goes somewhere, and it usually goes into scope that was never quite right.
We would rather be paid to find out. If the honest answer is that this shouldn’t be built, or shouldn’t be built yet, or should be built by somebody cheaper than us, you’ll hear it on day ten. You’ll still have the spec, the architecture, the estimate, and a guide to hiring well, to act on however you like.
Three ways to start. Each one ends with something you keep.
You do not need to know which service you want. Find the situation you are actually in — then check you are not ruled out underneath it.
Which one is you right now?
Proof of Concept
Find out whether it works before you fund it.
This is you ifYou know what you want built, and you want to watch a real piece of it run before you commit the budget.
- A working feature in your repo, live on your data, inside a week.
- A real answer to “can this actually work here” for $2,500, instead of a six-figure guess.
- The code, whether or not you take it any further with us.
Not you if
- Nobody internally agrees on what to build yet. AI Blueprint →
- The build behind this is already six figures and unspecified — one working feature will not de-risk it. Discovery Sprint →
AI Blueprint
Spend the budget on the thing that pays it back.
This is you ifSomething is clearly costing you time or money, and nobody can tell you which fix is worth making first.
- Three to five opportunities ranked by what each returns, with the arithmetic behind the ranking.
- An ROI model you can defend to your board, and use with any team — not only ours.
- Permission to not build: when the answer is fix the process first, we say so.
Not you if
- You already know which single process to fix and only need it specified and priced. Discovery Sprint →
- There is only one candidate on the table — ranking five of them is not worth $5,000.
Discovery Sprint
Know the real number before you sign for it.
This is you ifYou know the problem, and you are about to commit six figures to an estimate nobody has actually checked.
- A clickable spec of the thing itself, so the argument about scope happens now and not in month three.
- A price written by the engineer who would build it — at three budget levels, not one number.
- The whole package to take to any firm, including one that is not us.
Not you if
- You only want to see one idea work first. Proof of Concept →
- The build behind it is under roughly $55,000 — this is hard to justify. Email us, there is a smaller version that fits.
Ten working days. Then you decide, with all six in front of you.
$8,000 fixed. $4,000 back if you build with us within 90 days. Everything is yours either way.
