Co-Founder Agreement & Equity Split in India: Legal Template, Vesting & Pitfalls
Why Equal 50-50 Equity Splits are Dangerous
Splitting equity 50/50 without vesting is the single most common mistake early-stage founders make. If one founder quits after 3 months to take a corporate job while the other works for 5 years, the departed founder retains half the company's value as 'dead equity'—making the startup completely uninvestable for angel investors and venture capitalists.
The Standard Dynamic Equity Split Framework
Instead of arbitrary guesses, calculate equity allocation based on concrete historical and forward-looking contributions:
| Contribution Dimension | Weightage in Formula | Evaluation Criteria |
|---|---|---|
| Initial Idea & Core IP / Patent | 10% – 15% | Proprietary code, filed patents, domain assets |
| Early Capital Contribution | 15% – 25% | Cash funded for initial incorporation, servers, MVP |
| Full-Time Commitment & Opportunity Cost | 30% – 40% | Drawing zero salary full-time vs part-time advisory |
| Execution Capability & Technical Domain | 20% – 25% | Building the tech stack vs leading sales & fundraising |
Standard 4-Year Reverse Vesting with 1-Year Cliff (Explained)
Under Indian corporate law (Companies Act, 2013), founders issue equity subject to contractual reverse vesting:
- 1-Year Cliff (0% Vesting): If a co-founder leaves before completing 12 full months, they forfeit 100% of their unvested shares, and the company repurchases them at nominal par value (e.g., ₹10/share).
- Monthly Vesting Thereafter: After month 12, the founder vests 25% of their total equity. The remaining 75% vests in equal monthly increments of 1/48th over the next 36 months.
- Single / Double Trigger Acceleration: If the startup is acquired (Change of Control) and the founder is terminated without cause, their remaining unvested shares vest immediately.
Critical Legal Clauses Every Co-Founder Agreement Must Have
- Intellectual Property (IP) Assignment Clause: Explicitly states that all code, designs, client lists, trademarks, and algorithms created by any founder belong 100% to the Private Limited company, not the individual.
- Roles & Decision-Making Authority (Tie-Breaker): Clearly designate the CEO with ultimate day-to-day operational tie-breaking power to avoid boardroom deadlocks.
- Good Leaver vs. Bad Leaver Terms: Defines whether departing founders can retain vested shares (Good Leaver: medical illness/termination without cause) or must sell them back at par value (Bad Leaver: fraud, theft, competing business).
- Non-Compete & Non-Solicitation: Restricts departed founders from starting or advising direct competitor businesses for a minimum of 24 months post-exit.
