Philosophy

Reward what moves the project forward: time risk, cash risk, real assets, and proof with users/revenue.
Use simple defaults first; then tune weights to your team’s values.
Recalculate periodically as contributions change (dynamic, not one‑and‑done).

Collaborate with brilliant builders.
Own what you ship.
