How should startup founders structure equity among themselves?

Equity should be divided based on contributions, roles, and future commitment, typically using vesting schedules and considering factors like idea origin and risk.

Structuring founder equity requires careful consideration of multiple factors and should ideally be addressed early in the startup journey, preferably before incorporation.

Key factors for equity allocation:

• Contribution levels: Consider past work, financial investments, and intellectual property contributed
• Future roles: CEO typically receives slightly more equity (30-50%), with other C-level founders receiving 10-30%
• Risk and commitment: Full-time founders usually receive more equity than part-time contributors
• Expertise and networks: Unique skills or valuable connections may justify larger allocations

Essential protective mechanisms: Implement vesting schedules (typically 4 years with 1-year cliff) to protect against early departures. Include "good leaver/bad leaver" provisions that determine what happens to unvested equity when founders leave.

Common structures:

• Equal splits work when founders have similar contributions and commitment levels
• Weighted allocation based on role hierarchy (CEO gets more)
• Dynamic equity models that adjust based on ongoing contributions

Documentation requirements: Create a shareholders' agreement outlining equity terms, transfer restrictions, and decision-making processes. Include drag-along and tag-along rights for future investment scenarios.

Timing considerations: Address equity early but remain flexible for adjustments during the first 6-12 months as roles crystallize.

Avoid leaving equity discussions until fundraising begins, as this creates unnecessary pressure and potential conflicts.
