Co-founder exit: the clean separation

A co-founder leaving is common and survivable. It is clean when the vesting, the leaver terms, the buyback price and the handover were written into the agreement before anyone wanted to leave.

Co-founders leave. Some burn out, some disagree about the direction, some are asked to go, and some simply find that the company they are building is not the one they wanted. The departure itself is survivable. What does damage is a separation negotiated from scratch, by two people who no longer trust each other, over shares worth more every month the argument lasts.

A clean separation is one where the answers already exist on paper. This lesson covers what to write before anyone wants to leave, how to run the separation when someone does, how shares actually move in an Indian private company, and what to do when it is contested.

Write the exit while you still like each other

Every rule that makes a separation clean has to be agreed when it feels unnecessary. Michael Seibel’s advice to founders at Y Combinator is blunt: if you fear what will happen if you have to break up with a co-founder, make sure you have a proper vesting schedule. Under the usual schedule, someone who leaves or is fired within the first year walks away with nothing, which means a mismatch can be fixed without harm in year one.

The [co-founders’ agreement](/library/cofounders-agreement-what-it-must-contain) should hold five things for this moment. The vesting schedule, usually four years with a one-year cliff and monthly vesting after, with any credit for work done before the agreement. The leaver definitions, good and bad. The price at which shares return in each case. The mechanism by which they return, and who has the right to buy them. And the handover obligations: notice period, transfer of knowledge, confidentiality and non-solicitation. The [vesting lesson](/library/vesting-and-the-cofounder-cliff) draws the schedule; this lesson is about using it.

Good leaver, bad leaver and the price

A good leaver is someone who leaves for a reason the agreement accepts: resignation after a notice period, ill health, death, or removal without cause. A good leaver keeps vested shares, and unvested shares return. A bad leaver is someone removed for a narrow, listed set of reasons: fraud, a serious breach of the agreement, joining a competitor while still a shareholder, or walking out without notice. A bad leaver loses the unvested shares and sells the vested ones at a discount.

Two drafting points decide most disputes. First, keep the bad-leaver list short and factual. A clause that makes “poor performance” a bad-leaver event turns every separation into a fight over the definition, because the price difference is large. Second, state the price as a formula, not a negotiation. Brad Feld’s model vesting clause gives the company the option to repurchase unvested shares at the lower of cost or current fair market value; for Indian founders, who usually subscribed at face value, that is effectively face value. The same post notes that founders often receive credit for time already served when investors arrive, typically a year when the company was started a year or more before the investment.

At the defaults, a co-founder with 30 per cent leaves twenty months in as a good leaver. They keep 12.5 per cent of the company, worth ₹5 crore at a ₹40 crore valuation, and 17.5 per cent returns at face value for the remaining founders or the next senior hire. Switch to bad leaver at half of fair value and the same founder keeps nothing, while someone must find ₹2.5 crore in cash to buy the vested shares, which is often more than the company or the remaining founders have. That is why the bad-leaver price needs to be affordable as well as punitive, and why the definitions must be narrow. Move the months below twelve and nothing has vested at all, which is the cliff doing its job.

The separation is decided the day the agreement is signed. Everything after that is either following the document or fighting over its absence.

How the shares actually move in India

Indian founders usually hold shares outright from incorporation rather than options, so vesting works in reverse: the shares are owned on day one and the agreement obliges the leaver to transfer the unvested part back. That obligation has to be enforceable, which means it must sit in the articles of association as well as the shareholders’ agreement, because a transfer restriction that appears only in the agreement may not bind the company. The [shareholders’ agreement lesson](/library/shareholders-agreement-what-you-are-signing) explains why.

There are two common routes. The first is a transfer: the leaver sells the shares to the remaining founders, to a nominee or to an employee trust for the option pool, at the agreed price, on a transfer deed with stamp duty paid. The second is a buyback by the company under section 68 of the Companies Act, 2013, which comes with conditions on the source of funds, the size of the buyback and the approvals required; have the company secretary check them against the latest accounts before promising one.

The tax differs by route. For buybacks on or after 1 October 2024, the Finance (No. 2) Bill 2024 memorandum treats the sum paid as dividend in the shareholder’s hands, and the cost of the shares bought back as a capital loss that can be set off against other gains. A transfer is instead taxed as a capital gain for the seller, and a sale well below fair value can create tax questions for the buyer. The Income-tax Act, 2025 replaced the 1961 Act from 1 April 2026, so confirm the current provisions with an adviser before choosing. Checked 10 October 2026.

The handover, the investors and the story

Agree a handover of thirty to ninety days in writing: which responsibilities pass to whom, which relationships with customers, investors and staff are introduced, which credentials and documents are handed over. Confirm in the separation agreement that every piece of intellectual property the leaver created belongs to the company; the [IP assignment lesson](/library/ip-assignment-company-owns-what-you-built) covers the gaps that appear here. If the leaver is a director, record the resignation and file the change with the Registrar within the time the law allows.

Tell the lead investors before the team, and the team before anyone outside. The two founders should agree one short account, true and without blame, and both should give it, ideally together. Employees will be asking themselves whether the company is in trouble; the answer should come with the plan for the leaver’s responsibilities. Customers and the market need one line, not the story.

A good leaver who keeps vested shares becomes a passive shareholder, sometimes a large one, in a company they no longer work for. Decide in the agreement what that means. What information do they receive, and how often? Do their shares carry votes on ordinary resolutions, and should they sign a proxy or a voting agreement in favour of the board? Are they bound by the drag-along and tag-along terms the investors hold, so that a future sale cannot be blocked by one former founder? Do they keep the right of first refusal on new shares, or does it lapse? These are not hostile questions. A former co-founder holding 12 per cent who cannot be reached when the company needs a special resolution, or who refuses to sign a transfer at an acquisition, can delay a deal for months. Agree the answers while the separation is friendly, and record them in the separation agreement, not in an email.

When it is contested

If the founders cannot agree, use the dispute clause the agreement should already contain: a fixed period of negotiation, then mediation, then arbitration. The Mediation Act, 2023 provides for voluntary pre-litigation mediation in civil and commercial disputes, completed within a maximum of 180 days, with a settlement that is final, binding and enforceable as a court decree. For a co-founder dispute, where the company’s value is falling every month the dispute runs, a fast private settlement is worth more to both sides than a slow public win. The [co-founder conflict lesson](/library/cofounder-conflict-before-it-becomes-war) covers how to stop it getting here.

The separation checklist

Before anyone leaves, once and then at every financing: vesting, leaver definitions, prices and the transfer mechanism written into both the agreement and the articles; the dispute clause with mediation before arbitration; and a check that the company could actually afford a bad-leaver purchase. When a co-founder leaves, in order: confirm the leaver category and the vested count against the schedule; compute the price; choose the route, transfer or buyback, with the tax position for both sides; sign the separation agreement with the handover plan and the IP confirmation; tell the investors, then the team, then the market; complete the share transfer and the filings; reallocate the returned shares, to the remaining founders or the option pool, by a board decision recorded in the minutes. Within three months: review what the agreement did not anticipate and amend it for everyone who remains.

Nothing here is legal, tax or investment advice. Have the agreement, the articles and any separation drafted and reviewed by a lawyer who works on Indian shareholder disputes.
