● ENGAGEMENT SHAPES

## Three ways to hire the lab.

The sprint is the lead promise, not the ceiling. Same senior engineers, same eval discipline, same source ownership at every milestone, sized to the work in front of you.

[01 · SPRINT

### Eight weeks

Fixed price · fixed scope

First builds, MVPs, focused outcomes. Hypothesis to in-market with a written brief on day one and a runbook on day fifty-six.

MVP engagement](https://www.kensink.com/mvp/) [02 · PROGRAM

### Multi-phase

Quarterly milestones · fixed price per phase

Enterprise builds, regulated work, multi-system integrations. Two to four phases over six to twelve months, each phase its own written scope and number.

Enterprise engagement](https://www.kensink.com/enterprise/) [03 · PARTNERSHIP

### Ongoing

Fractional · monthly · explicit scope

Eval ops, model migrations, on-call architecture for teams that already shipped. A senior bench you can keep, not a retainer that bills past usefulness.
