How a build runs

/ 03 — Process
01

Discovery

We map the calls and chats you handle now, and where an agent earns its place.

02

Build

We write the agent on your cloud, wired into your tools. Real code, not a wrapper.

03

Deploy

It goes live in production and we tune it against real traffic, not a demo.

04

Support

Optional retainer for changes and upkeep. Or take the source and run it yourself.
