Legal Due Diligence Checklist for Startup Acquisitions

  • All stock purchase agreements, option agreements, and SAFE/note documentation
  • Option plan and grant schedule with vesting details
  • All warrant agreements
  • Any side letters, rights of first refusal, or co-sale rights

Intellectual Property

  • IP assignments from all founders, employees, and contractors
  • Patent applications and issued patents
