How to Split Equity Between Co-Founders: A Practical Guide for Indian Startups

CA-reviewed · Published
The equal split — 50/50 for two founders, 33/33/34 for three — is the most common choice and the most commonly regretted one five years later. The conversation you avoid having at the start about relative contribution becomes the lawsuit you don't avoid having at exit. This guide explains how to have the conversation correctly.
The Contribution Framework: What Actually Gets Measured
Equity split should reflect expected future contribution, not just historical effort. The five factors that matter in most founding teams are: idea origination (lower weight than most founders think — ideas without execution are worth very little), technical contribution (does one founder build the product?), business development and customer access (who opens doors?), capital at risk (has one founder left a significantly higher-paying job or invested personal capital?), and commitment level (full-time vs part-time at founding).
A useful exercise: have each founder independently score themselves and each other on each factor using a 1–10 scale. Then weight the factors by importance for your specific business. The resulting calculation rarely gives you the final answer, but the conversation about why scores differ is where the important clarity emerges.
For most two-founder startups, the honest range for the senior or lead founder is 55–70%, with the remaining 30–45% for the co-founder. Perfectly equal splits work when contribution genuinely is equal, but that's rarer than founders admit at inception.
Vesting: The Structure That Protects Everyone
Whatever split you agree on, the shares should be subject to vesting — a schedule under which founders earn their equity over time rather than receiving it all on day one. Standard vesting in Indian startups follows the 4-year/1-year cliff model: no equity vests in the first 12 months (the cliff), and after the cliff, 25% vests immediately, with the remaining 75% vesting monthly over the following 36 months.
Vesting protects all parties. If Co-founder B leaves at month 11 after the cliff, they take nothing. This prevents a co-founder from walking away with 40% of the company after 11 months and blocking the remaining founders from fundraising. Most institutional investors won't fund a company where a departed founder holds unvested equity — they will ask for it to be clawed back as a condition of investment.
The vesting schedule should be documented in your Founders Agreement before anyone starts working, not after. Trying to impose vesting retrospectively on a co-founder who's already been told they 'own' their shares creates legal risk and personal conflict.
What to Include in the Founders Agreement
A Founders Agreement is a private contract between founders that sits alongside the company's statutory documents (MoA, AoA). It should cover four key areas beyond equity allocation:
IP assignment: a declaration that all IP created by each founder in connection with the business belongs to the company, not to the individual. This is frequently overlooked and creates significant problems in VC due diligence when not in place.
Role definition and decision rights: who makes which decisions? What requires unanimous consent vs majority vs CEO discretion? Disagreements on operational decisions are far more common than equity disputes, and most founders have no framework for resolving them.
Departure provisions: what happens to the equity of a founder who leaves? Does it all lapse? Is there a buyback right for the company? What is the strike price? Good-leaver vs bad-leaver distinction (different terms for voluntary departure vs termination for cause) should be spelled out explicitly.
Non-compete and non-solicitation: what can a departing founder do in the 12–24 months after leaving? Soliciting your co-founder's employees or customers is typically the most damaging near-term departure scenario.
Key takeaway
Spend the uncomfortable hour having the equity conversation explicitly, document it in a Founders Agreement with vesting, IP assignment, and departure provisions, and move on. The startups that fail over co-founder disputes almost always had the warning signs in the founding conversation they chose not to have.
Frequently asked questions
Is a 50/50 equity split between co-founders ever a good idea?
Yes, when genuine contribution is equal, both founders are full-time from day one, and you have a clear deadlock resolution mechanism — typically a defined decision-making structure where one person has the final say in their domain. 50/50 splits create board deadlock risk, since each founder controls 50% of votes. Institutional investors generally prefer a clear CEO with a majority or a defined tiebreaker mechanism. The problem isn't the percentage — it's the absence of a governance solution to 50/50 stalemates.
Can a founder receive salary plus equity in an Indian startup?
Yes. Equity and salary are completely separate. A founder can hold shares (equity) and simultaneously receive a founder salary from the company. The salary is a company expense paid from operating cash, while equity is the founder's ownership stake. Many early-stage startups pay below-market salaries to conserve cash while compensating founders with equity for the opportunity cost. This is contractually clean and standard practice.
What is a founder's equity cliff and why does it matter?
The cliff is the minimum employment period before any equity vests. In a standard 4-year/1-year cliff structure, a founder must remain with the company for at least 12 months before receiving any vested equity. At month 12, 25% vests immediately. After that, vesting is monthly. The cliff exists to prevent a founder from joining, collecting equity from day one, and leaving early. For investors, the cliff is critical — they're investing in the team's continued commitment, not their past work.
What happens to a co-founder's equity if they leave before the cliff?
In a properly structured agreement, a co-founder who leaves before the cliff loses all their equity — it either lapses or is subject to a buyback by the company at par value (the original issue price, often ₹10 per share). This is the purpose of the cliff. In practice, disputes arise when the agreement is not explicit about bad-leaver vs good-leaver treatment, or when the departing founder argues they were 'pushed out' rather than choosing to leave. Getting the language right in the Founders Agreement is essential.
When should you bring in a third co-founder?
Bring in a third co-founder when you have a genuine skill gap that cannot be filled by a hire — when the capability is so central to the business that it needs to be represented at the founding table with equity and strategic authority. The most common legitimate third co-founder roles are: CTO in a technical startup where neither founding partner can code, and a domain expert in a highly regulated field who brings network and credibility that can't be bought. Avoid giving co-founder equity to early contributors who should really be early employees with competitive packages.
