Most software projects die in the proposal stage, not the build stage. A vendor hands over a forty-page statement of work, a buyer signs it under pressure, and three months later everyone is arguing about what “included” meant on page 12. We stopped operating that way two years ago. Now we sell a one-week Sprint first, at a fixed $4,500, before we quote anything larger. This is not a loss-leader or a discovery tax. It is the mechanism that makes every project after it go better.
Why straight-to-project usually breaks
A twelve-week build proposal asks a buyer to commit to a number nobody has stress-tested against reality. The vendor estimates based on requirements that sound clear on paper. The buyer approves based on a price that sounds reasonable in a meeting room. Nobody has actually looked at the hard parts yet: the legacy database, the third-party API with missing documentation, the three departments that have different opinions on what “approval” means.
Scope drift starts on day one, not week eight. By the time the overrun shows up on a status call, both sides have invested too much to walk away cleanly. The buyer feels trapped. The studio feels resentful that it underpriced. This is the default outcome of straight-to-project engagements, not an exception. The incentive structure produces it reliably.
If neither side has worked together before, committing to a six-figure project on the strength of a proposal is not buying software. It is placing a bet.
What a one-week Sprint actually delivers
A Sprint is not a kickoff call and a vague “findings document.” It is a fixed-scope engagement with a real artifact at the end. Depending on what the buyer needs most, that artifact is one of:
- Technical audit report — We go through your existing codebase, infrastructure, or vendor contracts and produce a written assessment of what is solid, what is fragile, and what is blocking your next move.
- Architecture sketch — A documented proposal for how the system should be structured, with trade-offs called out explicitly and the major integration points identified.
- Working prototype — A thin but real slice of the product, built to test assumptions rather than to ship to users.
- Scoped MVP plan — A project brief with a realistic timeline, identified risks, and a line-item budget anchored to actual complexity.
The Sprint runs on a two-week wall clock, costs $4,500 fixed, and does not grow. There is no “discovery phase” that expands to fill available time. The constraint is intentional: a week of focused work reveals the hard parts faster than a month of open-ended research.
The Sprint also functions as a working relationship test. Both sides find out whether they communicate well, whether the buyer can make decisions at pace, and whether our approach fits the culture of their team. That information has real value before anyone signs a six-figure contract.
How buyers use it
The three most common Sprint requests we receive right now map to three distinct problems buyers are trying to solve.
AI feasibility audits. A team wants to add Claude to their product workflow but is not sure whether the problem actually needs a large language model, or whether a simpler rules-based approach would work better and cost less. We run the evaluation, test the models against real data, and give a written recommendation. No commitment to build anything afterward.
Architecture reviews. An engineering team is about to commit to a stack or a structural decision and wants an outside perspective before the decision becomes expensive to reverse. We spend a week inside the codebase and the problem domain, then write up what we think they should keep, change, and watch out for.
Prototypes. A buyer wants to see what a working version of their idea looks like before deciding whether to fund a full build. We build a thin but functional version, enough to show to stakeholders and test core assumptions.

Why this is good for us
We never quote a $50K project blind. By the time we send a project proposal, we have spent a week inside the actual problem. We know where the complexity lives. We know which third-party systems are badly documented. We know whether the client team can make decisions quickly or whether every change needs three approval layers. The Sprint output becomes the artifact we anchor the larger proposal on, which eliminates the majority of scope drift before it starts.
Bad-fit clients self-select out at the Sprint stage. If the engagement feels wrong after a week, neither side has to manufacture an exit from a six-month contract. The Sprint acts as a filter, and that filter protects both the buyer and us.
There is also a compounding effect. Every audit and architecture sketch we produce sharpens our pattern recognition on the next project. Sprints make us better at estimating, not just better at the specific engagement.
What happens after the Sprint
Three outcomes are possible, and all three are good.
- Convert to Project — We agree on a scoped build in the $15K to $75K range, anchored to the Sprint artifact. The proposal is faster to write and easier for the buyer to approve because we have both lived inside the problem.
- Convert to Retainer — The buyer wants ongoing engineering capacity rather than a one-time build. We engage at $3,500 per month.
- Part ways — The scope is not right, the timing is wrong, or the fit is not there. The buyer keeps the audit artifact and uses it with whoever they hire. No hard feelings.
Roughly 70% of Sprints in our current pipeline convert to a Project or Retainer. That number is not a marketing claim; it reflects that Sprints filter out the bad-fit work early, so the 70% who proceed are genuinely ready to build.
For buyers in US enterprise or government contexts: a $4,500 Sprint sits below most departmental approval thresholds. That means work can start in days rather than waiting for a procurement cycle to complete. If the Sprint confirms the project is worth pursuing, the larger approval process can run in parallel with the Sprint output in hand.
