Recommended: 4-year vesting with 1-year cliff
Regardless of your split, always implement vesting for all founders. Standard terms: 4 years total, 1-year cliff (25% vests at month 12, then monthly thereafter). This protects everyone if a founder leaves early. You should engage a startup lawyer to formalize this in a Founders' Agreement.
This calculator provides a starting point for conversations — not legal advice. Every situation is different. Consult a lawyer before finalizing any equity arrangements.
