What Are Secondary Transactions and How Do Founders Sell Shares Before Exit?

A secondary transaction is when a founder sells existing shares they already own to a new buyer before a company acquisition or IPO.

No new money enters the company. The founder gets cash. A new investor gets the equity. The company's cap table changes, but the company's bank account does not.

Why Founders Do This

The most common reason: a founder has 90% of their net worth tied to illiquid equity. They have a mortgage, a family, and a business that may take 5-10 more years to exit. A secondary gives them liquidity now without waiting for the full exit event.

A founder who takes $5-10M off the table through a secondary can make better decisions. They are not as desperate to take the first acquisition offer. They can wait for the right buyer at the right price. The psychological shift is real and measurable in the quality of deals founders accept.

How Secondaries Work

Direct secondary: A new investor buys your shares directly. Requires company approval and existing investor consent (usually a right of first refusal from existing investors).

Tender offer: The company or a new investor offers to buy shares from any or all existing shareholders at a set price. Common in late-stage rounds for VC-backed companies.

Secondary fund or marketplace: Platforms and funds specialize in buying illiquid startup equity. They typically pay 60-80 cents on the dollar against the last round price for well-known companies.

The Process

1. You identify a buyer (existing investor doing a pro-rata top-up, new growth fund, secondary-focused fund, or direct negotiation) 2. Check your shareholder agreement for right of first refusal (ROFR) provisions — most VC-backed companies have these 3. Existing shareholders get first right to match the price 4. If they pass, the transaction closes 5. Cap table is updated

A simple direct secondary in a VC-backed company takes 4-8 weeks. A tender offer coordinated with a new round can take 2-4 months.

What Investors Think

Most investors are fine with founders taking modest secondaries. "Modest" is typically defined as 10-20% of your holdings. Taking 80% off the table before the business is proven sends a signal that management does not believe in the upside.

The framing matters. "I want to reduce personal risk and buy a house" is understood. Investors do not want founders going into a process purely motivated by fatigue or doubt.

Tax Considerations

Secondary proceeds are capital gains. If your shares are ISOs (Incentive Stock Options) that have been exercised and held for more than 2 years from grant and 1 year from exercise, you may qualify for long-term capital gains treatment. Structure matters significantly.

Work with a tax advisor before you agree to any secondary. The difference between ordinary income and long-term capital gains treatment on a $10M secondary is a $2-3M tax bill.

Secondaries in M&A Context

If you are in an acquisition process, buyers sometimes offer a founder secondary as part of deal structuring — especially if there is a large earnout involved. They let you take some cash at close and keep you economically motivated on the earnout by rolling equity into the acquirer.

Understanding this before you enter a process gives you negotiating leverage on the structure.
