Co-Founder Equity Split in India: A Practical Guide (2025)
5 March 20257 min read
Why equity splits matter
A bad equity split kills founders. It's one of the top reasons startups fail. Get it right early.
1. Equal vs unequal splits
Equal (50/50) works when:
- Both founders contribute equally (time, skills, capital)
- You're starting at the same time
- You're both full-time from day one
Unequal makes sense when:
- One founder brings the idea, domain expertise, or network
- One founder is part-time initially
- One founder is investing significant capital
Common mistake: Giving 50/50 to "keep peace" when contributions are unequal. Resentment builds later.
2. Vesting is non-negotiable
4-year vesting with 1-year cliff is standard:
- You earn your equity over 4 years
- Nothing vests in the first year (cliff)
- If someone leaves before year 1, they get 0%
- After year 1, they get 25% and continue vesting monthly
Why: Protects you if a co-founder leaves early. Without vesting, they keep their full equity even if they quit.
3. India-specific considerations
- Cliff: Some Indian founders skip the cliff. Don't. 1 year is standard.
- Tax: ESOPs and equity grants have tax implications. Consult a CA for your structure.
- Agreements: Get a founder agreement in writing. Even a simple one is better than nothing.
- Family pressure: If a co-founder is under family pressure to "get a real job," vesting protects you.
4. Common mistakes
| Mistake | Fix |
|---|---|
| No vesting | Add 4-year vesting with 1-year cliff |
| No written agreement | Draft a founder agreement (templates available) |
| Splitting equity before roles are clear | Define roles first, then split |
| Giving equity to "advisors" too early | Use advisor shares (0.25–1%) with vesting |
5. When to revisit
Revisit your split if:
- One founder goes part-time
- Another founder joins
- A founder leaves
- You raise funding (investors may ask for founder equity adjustments)
