Why Technical Co-Founder Equity Matters

The most successful startups are built by co-founder teams with complementary skills. A technical co-founder with strong equity alignment becomes a true owner invested in long-term success, not just a contractor executing someone else's vision.

Equity Structure Best Practices

Standard Equity Splits

Typical founder splits: 40-50% CEO/Business, 40-50% CTO/Technology. Vesting over 4 years with 1-year cliff standard.

Vesting Schedules

4-year vest, 1-year cliff protects both parties. Single-trigger vs double-trigger acceleration differs between Series A and later rounds.

Option Pool Allocation

Typical 20% option pool from founding allocated to early hires. Growth allocations at subsequent funding rounds.

Cap Table Management

Maintain clear cap table records with all equity allocations, vesting schedules, and dilution tracking. This becomes critical during fundraising when investors need complete clarity on ownership structure.

Exit Scenarios & Returns
