Why "proportional"
The Platform
Data : Need
The data a site collects should match the need for it.
We make hidden tracking measurable and public, so a site's privacy promises can be checked against what it really does.

The Advisory
AI : Humans
AI is only as valuable as the human judgment guiding it.
We help teams scale AI as an amplifier of their people, keeping human judgment in the loop and privacy in the design.
