Dispatches from the deep

The Logbook.

Development notes, product thinking, and the principles guiding DarkSea as our first software takes shape.

DarkSea Tax Planner is in development—a local-first way for sole proprietors in Japan to understand the money behind their business.

003

Privacy before features

Sensitive work deserves boundaries designed at the beginning—not privacy language added at the end.
