05 · OPERATING MODEL

Async. By default. Always.

No standups. No retros. No “quick syncs”. A 7-day cadence with two PR drops and a written changelog.

01

01 — Brief

A 40-minute async kickoff. You send the deck, repo, and a Loom of the problem. We send back scope + Linear seed.

02

02 — Sprint

7-day cadence. PRs land Tuesday and Friday. Comments in Linear, never on calls.

03

03 — Ship

Production handoff with typed components, Storybook, and a 30-min walkthrough recording.

04

04 — Iterate

The retainer rolls. Pause when the queue is empty. Cancel with 14 days’ notice.

Q2 · 3 SLOTS

Start a retainer.
Ship v1 in seven days._
