Startup Equity Guide

Key Terms

  • Stock Options: Right to buy company shares at a set price (strike price)
  • Vesting: Time-based earning of equity, typically 4 years with 1-year cliff
  • Cliff: Minimum period before any equity vests (usually 1 year)
  • Strike Price: Cost per share to exercise your options
  • 409A Valuation: Fair market value used to set strike prices

Important Considerations

  • Exercise options early for potential tax benefits (consult tax advisor)
  • Understand dilution from future funding rounds
  • Consider 83(b) election if exercising early
  • Know your option expiration date (typically 90 days after leaving)
  • Preferred stock has priority over common in liquidation
