Senderos
Software built through conversations can become difficult to understand once it grows beyond them.
Senderos is a new working surface for seeing a product as a whole—what exists, what was intended, and what needs attention next.

Approach
Problem firstBuild · Test · Revise02
The problem comes first.
We keep the form open until the problem is clear. Then we build, test and revise.
02
Build beyond the demo.
A convincing prototype is not yet a useful product.
03
Move when reality can answer.
We do not rush the question. Once there is something real to test, we move quickly.
