Critical Clauses to Watch In This Contract

Major Contract Risks & Recommendations

Immediate 100% Equity Ownership Without Vesting

high Severity

A co-founder leaves after three months but keeps 50% of the startup's equity, rendering the company uninvestable.

Recommended Negotiation Counter:Implement standard 4-year vesting with a 1-year cliff and accelerated vesting on acquisition (double-trigger).

Equal 50/50 Deadlocks Without Tie-Breaking Mechanics

high Severity

Disputes between equal partners freezing corporate decisions, payroll, and strategic hiring.

Recommended Negotiation Counter:Establish an independent advisory board member tie-breaker, shotgun buy-sell clause, or designated executive domain authority.

Unclear IP Assignment to the Corporate Entity

high Severity

Founders developing code or patents personally without formal assignment to the company prior to incorporation.

Recommended Negotiation Counter:Execute comprehensive Invention Assignment Agreements transferring all past, present, and future product IP to the company.

Immediate Red Flags

  • No buyback mechanism for departing founders' unvested shares at nominal value
  • Unrestricted rights for partners to sell shares to external third-party competitors
  • No drag-along or tag-along clauses for future company acquisitions
  • Permitting partners to launch competing ventures while holding equity

Negotiation Playbook

  • Document roles, expected weekly time commitments, and salary expectations upfront.
  • Include a Russian Roulette (Shotgun) or appraisal-based buyout clause for irreconcilable deadlocks.
  • Ensure all company intellectual property is formally assigned before writing any code or taking outside capital.
When to Seek Licensed Legal Counsel:Retain a startup attorney before formal incorporation or allocating cap table equity among co-founders.

Frequently Asked Questions

What is a 1-year cliff in founder vesting?

A 1-year cliff means that if a founder leaves before completing 12 months of service, they walk away with 0% of their equity. After 12 months, 25% vests immediately, with the remainder vesting monthly over years 2–4.

What happens if co-founders disagree 50/50 on a major decision?

Without a deadlock mechanism, companies often wind up in judicial dissolution (court liquidation). Partnership agreements avoid this via shotgun buy-sell clauses or assigning final tie-breaking votes to an independent advisory board.
