We build AI products on solid ground with direct calls to the model, boring infra, and senior people.

Kensink Labs is a small lab of senior engineers shipping production AI for SaaS companies. We integrate against the model the same way we integrate against Postgres. No agent frameworks, no orchestration vendors, no migrations every six months. Eight weeks, then it’s yours.

[FIG. 01 · ENGAGEMENT TIMELINE]

How an engagement is shaped, from discovery to handoff.

Four overlapping phases over roughly sixteen weeks. Discovery feeds the brief; the brief feeds the build; the build feeds a runbook your team can still understand six months from now.

Three columns hold
the lab up.

We do three things, and we are honest about what they are. Every engagement starts in one column and usually ends in another. The scaffolding is how the work travels.

P-01 / 03 · EMBEDDED

Engineering teams, embedded.

Two to four of our engineers join yours for an engagement of twelve to twenty weeks, with a published runbook and a working artefact at the end. We don't do retainers.

Lab dispatches, made public.

A field-notes practice on the side: short essays, the occasional open-source tool, the occasional public talk. The lab writes more than it speaks.

FIELD NOTES · 042 · 041 · 040

Recently filed,
short essays
from the lab.

Engineering notes, half-finished diagrams, the occasional rant about file formats. New entries every other Wednesday in the Dispatch.

NOTE · 04220 MAY 2026

The file format is the API.

A short brief on why our integrations team starts at the schema, never at the endpoint. Includes a diagram you can print at A4 and a fourteen-line Postgres migration.

NOTE · 04106 MAY 2026

Costing a feature in pages, not points.

Story points are an honest unit if you treat them like word counts. Here is how we write a feature like a chapter: outline, draft, edit, set, ship.

Why every engagement ends with a physically printed runbook, and what changed about our work the day we started doing it.
