The document two co-founders skip — and then litigate
Two people start a company on a handshake and a 50/50 split. Eighteen months later one of them is doing all the work, or one wants out, or the "silent" co-founder who left after three months still owns half the company. There is no worse time to negotiate who owns what than after the relationship has broken. The founders' agreement — signed at the start, when everyone is still friends — is the document that prevents the single most common way early startups die: the co-founder split. This is what it should actually contain, and the two clauses (vesting and IP assignment) that matter far more than the equity percentage everyone fixates on.
The equity split: almost never a reflexive 50/50
The instinct is to split equity equally because it feels fair and avoids an awkward conversation. That is exactly why it is dangerous — an equal split made to dodge a hard talk usually stops reflecting reality within a year. A defensible split weighs the things that genuinely differ between founders: who put in money, who is full-time versus moonlighting, who brought existing IP or a customer pipeline, whose experience de-risks the build, and who is actually running the company day to day. The percentage matters, but as the next section explains, how that equity is earned over time matters more than the number itself.
Founder vesting: the most important clause in the document
Here is the clause that saves companies. Founder vesting (technically "reverse vesting") means a founder's shares are issued up front, but the company keeps the right to buy back the unvested portion at a nominal price if the founder leaves early. The shares are earned over time by staying and working, not owned outright on day one.
The market-standard schedule is four years with a one-year cliff: nothing vests for the first year, then a quarter vests at the one-year mark, and the rest vests monthly (or quarterly) over the following three years. The effect is simple and powerful — the co-founder who quits after four months walks away with nothing, not with a permanent claim on half the company. Without vesting, an early departure leaves "dead equity" on the cap table that no future investor will accept, and that the remaining founders cannot recover.
Vesting is enforced through the same machinery as any other transfer restriction: the buy-back right has to live in the company's constitution to bind properly. As we explain in our guide to term sheets and shareholders' agreements, a share-transfer restriction that sits only in a side agreement and never reaches the Articles of Association is a classic gap — under the proviso to Section 58(2) of the Companies Act, 2013 it binds the signatories as a contract, but to bind the company robustly it must be in the articles. Employees vest their options on the same logic, which is a separate topic we cover in our guide to ESOP taxation.
Good leaver, bad leaver
Vesting usually pairs with a "leaver" distinction that decides what happens to the shares a founder has already earned when they exit:
- Good leaver — someone who leaves for a reason outside their control (serious illness, death, or by mutual agreement) typically keeps their vested shares, or is bought out at fair value.
- Bad leaver — someone who leaves in breach of the agreement, is terminated for cause, or walks out early may be required to sell even vested shares back at a nominal price.
The definitions are where the negotiation really happens, and vague drafting here is what ends up in court. They should be specific, not left to "as the board decides".
IP assignment: the trap that means the company doesn't own its own product
This is the clause founders most often get wrong, and it is the one investors' lawyers check first. Under Section 17 of the Copyright Act, 1957, the author of a work is its first owner — with an exception for work made in the course of employment, which belongs to the employer. That exception has a hole a startup drives straight into: the core product is usually built before the company is incorporated, when there is no company to be the employer. The code, the designs, the brand — all of it is personally owned by the founder who made it, and none of it automatically belongs to the company later.
So the company can be raising a round on the strength of a product it does not legally own. The fix is an explicit, written IP assignment: every founder assigns to the company all intellectual property they created for the venture, including everything made before incorporation. Without that assignment on file, a diligence review will stall the round until it is signed — and a disgruntled ex-founder can, in the worst case, claim the product is theirs. Assign the IP to the company in writing, early.
The non-compete that will not hold — and what to use instead
Founders routinely try to protect themselves with a clause saying a departing co-founder cannot start or join a competing business. In India, that clause is very likely void. Section 27 of the Indian Contract Act, 1872 makes every agreement that restrains someone from exercising a lawful profession, trade or business "to that extent void", and Indian courts have consistently struck down post-employment non-compete clauses as an unenforceable restraint of trade — a position reaffirmed by the Delhi High Court as recently as 2025. A restraint that operates during the engagement is fine; one that bites after a founder leaves generally is not.
So do not rely on a non-compete to hold a founder in place or punish them for leaving. The tools that actually work are the ones above and one more:
- Reverse vesting — the real deterrent. A founder who leaves early simply does not keep the equity, which aligns incentives far better than an unenforceable promise not to compete.
- Confidentiality and trade-secret protection — a restraint on using or disclosing the company's confidential information and trade secrets can survive even after departure, because courts have treated that as protecting property rather than restraining trade. This is where your post-exit protection genuinely lives.
- Assigned IP — if the IP already belongs to the company, a departing founder has nothing to take with them.
The rest of the agreement: roles, decisions, and deadlock
- Roles and titles — who is CEO, who owns product, who owns sales, so decision-making rights are clear from the start.
- Decision-making and deadlock — which decisions need unanimity, which are day-to-day, and how a 50/50 deadlock is broken before it freezes the company.
- Founder salaries and expenses — what founders draw and when it changes, so money never becomes the unspoken grievance.
- Time commitment — full-time versus advisory, and what happens to equity if a founder never goes full-time.
How this feeds into your first funding round
A founders' agreement is not a one-off. At the first priced round it is largely absorbed into — and overridden by — the shareholders' agreement and the amended articles, so the vesting, leaver and transfer terms you agreed early get re-papered into the documents investors rely on. Getting the founders' agreement right early makes that transition clean; getting it wrong (no vesting, unassigned IP) is what turns diligence into a fire drill. The mechanics of that round are in our term sheet and SHA guide, and the wider founder journey starts with our Startup India and DPIIT recognition guide.

Verification note: The legal positions stated here — that under Section 17 of the Copyright Act, 1957 the author of a work is its first owner, subject to the employment exception, so intellectual property created by a founder before the company was incorporated is not automatically owned by the company and must be assigned to it in writing; and that under Section 27 of the Indian Contract Act, 1872 an agreement restraining a person from exercising a lawful profession, trade or business is void to that extent, so post-employment non-compete clauses are generally unenforceable as a restraint of trade (while restraints operating during the engagement, and the protection of confidential information and trade secrets, may be enforceable) — are based on the Copyright Act, 1957 and the Indian Contract Act, 1872 as available on India Code (indiacode.nic.in) and the settled line of Supreme Court and High Court authority, read with the share-transfer framework of the Companies Act, 2013 (mca.gov.in). Founder vesting, leaver terms and equity splits are contractual arrangements, not statutory requirements, and their effect depends on the specific drafting and on incorporation into the company's articles. This is general information, not legal advice; have your founders' agreement drafted and reviewed by your CA and a lawyer before relying on it.
