Scope first, named engineers, biweekly demos, and you keep the repo.
-
Scope before code
We write what is being built, what is excluded, integrations, dates and cost basis before the build starts. Changes get quoted before they get coded.

Talk to the people doing the work
You meet named engineers and designers. There is no account manager translating technical questions in both directions.
-
Working software every two weeks
Increments land on staging you can open and use. Progress you can click on beats progress in a status report.
