Approach

Four principles.

01

Independent by design.

Small, self-funded, accountable to users, not to investors or timelines we did not set.

02

Useful before novel.

We reach for AI when it solves a real problem, not to decorate one.

03

Built from lived experience.

Every product begins with a friction we have felt ourselves.

04

Quiet software.

Tools earn their place by staying out of the way.
