Startup Legal Checklist: Formation to Exit (2025)

This comprehensive legal checklist guides founders through every stage—from incorporation to exit—covering entity formation, equity splits, IP protection, compliance, fundraising, and growth-stage legal requirements.

Why this checklist matters:

  • Avoid costly mistakes: Missing 83(b) elections costs founders tens of thousands in taxes
  • Investor readiness: Clean legal foundation accelerates fundraising
  • Regulatory compliance: GDPR, CCPA, employment law violations carry severe penalties
  • Exit preparation: M&A due diligence reveals legal gaps that delay or kill deals

This checklist covers:

  • Pre-incorporation planning (entity selection, founder agreements)
  • Incorporation and initial filings (Delaware C-corp, EIN, state registrations)
  • Equity structure (founder stock, vesting, 83(b) elections, option pool)
  • Intellectual property protection (trademarks, patents, trade secrets, IP assignments)
  • Compliance (privacy laws, employment law, securities regulations, data security)
  • Fundraising legal requirements (SAFEs, convertible notes, Series A documents)
  • Growth stage (board governance, international expansion, M&A preparation)

Timeline: 1-2 weeks Cost: $0-$500 (trademark search via attorney)
