A short list of the things that come up on the first call. If yours isn't here, write to us and we'll answer it on the next one. [See all twenty-three ↗](https://www.kensink.com/contact) Yes, forty-seven times so far. The trick is that we scope the smallest valuable thing in week one, then defer everything else to the runbook. We will turn down work that we can't scope into eight weeks. Then we shape it as a multi-phase program (quarterly milestones, fixed price per phase) or an ongoing partnership (fractional senior engineering for post-launch teams). Same evaluation discipline, same source ownership at every milestone. Sprints are the lead promise; they're not the only one. Less surface area, fewer migrations, lower bills. We integrate against the LLM API the same way we integrate against Postgres. It's a tool, not a platform. Our clients keep that bet for years. You own the code, the prompts, the evals, and the runbook on day one. There is no license, no lock-in, and no retainer that bills past cutover. Two senior engineers, named, on the contract. There is no junior team behind the curtain. The people you meet on day one are the people writing every line. We carry a 90-day warranty. If a regression ships from our code, we fix it on our dime, with no retainer and no rebill. START A BUILD · Q3 ′25 · 2 SLOTS ## Bring a real problem. We'll bring code on day one. No discovery decks, no statement of work that takes a month. Bring the problem and you will hear back from a senior engineer, not a sales rep. 047 Engagements shipped 8 weeks Problem to live 100% Code you own [Book a 15-min intro→](https://www.kensink.com/contact) FIXED SCOPE · 8 WEEKS 2 SLOTS LEFT LEAD TIME 3–4 WEEKS
