How we work
A process with no black boxes.
Most projects go from first call to launch in six to ten weeks. Here’s exactly what happens in between.
- 01
Discovery call
Week 0Thirty minutes, no slides. We look at where time and money leak today and whether AI is genuinely the right fix — sometimes it isn’t, and we’ll say so.
- 02
Scope & prototype
Week 1–2A fixed-scope plan with milestones and a clickable prototype or working agent demo on your own data, so you see it before you commit.
- 03
Build in the open
Week 2–8Weekly demos, a shared board and a staging link you can poke at any time. You talk to the engineers doing the work, not an account manager.
- 04
Launch & look after
OngoingWe ship, watch the numbers, tune prompts and flows from real conversations, and stay on for support once you’re live.
