How we start

01

Intro call, 30 minutes

With the founder, not a sales manager. We decide together whether it makes sense to continue.

02

Audit, 2 weeks, fixed price

Read access to the repo, then a written report: architecture, risks, upgrade path, estimate.

03

First milestone, 4 to 6 weeks

A scoped piece of work with a clear definition of done. You see how we work before committing to more.

04

Ongoing

Dedicated engineers, weekly demos, monthly review. Leave any month with 30 days notice; the code and docs are yours.

Why a team, not freelancers

They already work together

They already work together

Same people for years, own CI, own QA, own code review. No onboarding tax every time you scale.

Nothing is locked in

Nothing is locked in

Your repo, your infra, your accounts. Documentation and handover are part of the job, not an extra.
