Model update
The 25/75 model is no longer the offer.
Blockchain Lab now uses The Venture Builders. The studio stake is 20% for 48 months. Eighty percent is reserved for founders, employees, advisers, partners and future capital.
What changed
The studio line moved from 25% to 20%. On a founder-originated venture the lead founder starts at 40%, not 35%. Vesting still reaches 50% at month 12 and 100% at month 48. The months 12–24 contribution window, the independent director, and the 15% external-financing shield remain.
