How we work

From call to production in 14 days.

No six-week discovery. We scope tight, ship a slice, iterate with you.

01

Day 0 · Discovery call

20 minutes. We pick the one workflow worth automating first. No deck, no demo.

02

Day 1–3 · Spec + estimate

Written scope, integrations, fixed price, fixed date. You sign or you don't.

03

Day 4–12 · Build

We build against a staging copy of your data. Daily Loom updates. Shared Slack channel.

04

Day 13–14 · Ship + train

Live in production. We train your team. First month of fixes is included.

Let's talk

20 minutes.
No deck. No demo.

Tell us about the workflow you'd automate first. We'll tell you whether it's worth it — even if the answer is no.
