01
Senior-only team
No juniors. No handoffs mid-project. The same people who scope your project build it.
02
Weekly working demos
Every week you see working software — not a status update, not a slide deck. Actual progress.
03
Fixed-price sprints
You know the cost before we start. Scope is defined, agreed and protected.
