Why secondaries became normal
The average time from founding to IPO is now ~10 years, up from ~7 a decade ago. The secondary market grew accordingly: more than $100B in private secondary volume traded in 2024, and the market is still expanding. Most large growth and late-stage funds now actively buy secondary stakes alongside primary checks — it’s no longer a sign of distress, it’s a standard part of round construction.
How founder secondaries work
At a priced round — typically Series B and later — the new investor agrees to put $X into the company as a primary investment, plus $Y to buy existing shares from founders and early employees at the same price per share. Typical founder secondary: 5–15% of the total round size, capped per individual founder, and almost always conditional on the founder signing a new 2–4 year vesting schedule tied to continued employment. Walking away right after a secondary is not an option any serious investor will allow.
What investors will actually accept
A few rules of thumb in the current market:
- Founders can usually take some chips off the table starting at Series B. At Series C and beyond, it’s expected.
- Total founder secondary is rarely above 10–15% of the round in a single transaction. Larger amounts require a dedicated tender offer process.
- Boards tend to approve it when the founder’s remaining ownership is still healthy — typically 20%+ post-secondary — and when the founder has been building for 4+ years.
- Early employees with meaningful vesting increasingly get a small allocation in the same tender, which helps retention at a critical growth stage.
- Lead investors sometimes structure the secondary at a small discount (5–10%) to the primary price as compensation for providing liquidity.
The hidden risks
- Tax treatment varies significantly by jurisdiction. In the US, selling shares that qualify as QSBS before the 5-year holding period voids the exclusion — a mistake that can cost 7-figures in unnecessary capital gains tax. Plan the timing with a tax advisor before you negotiate the secondary.
- Optics matter. A founder who tries to take 30% off the table at Series B signals “I’m not fully committed to this outcome.” Investors will price that perception in or walk away from the round entirely.
- Secondary buyers — particularly dedicated secondary funds rather than lead investors — often demand information rights, pro-rata rights in future rounds, and board observer seats that surprise founders years later. Read the shareholder agreement carefully.
What this means for you
If you’re post-Series B, secondaries should be a planned conversation at your next round, not an emergency one when you’re cash-stressed. The right time to negotiate them is when you have leverage — at the close of a competitive round, not between rounds when you need the money. The right amount is enough to remove meaningful personal financial stress — not enough to signal you’ve mentally moved on.
Frequently Asked Questions
Q: How much can a founder realistically take in a secondary at Series B? A: At Series B, founder secondary transactions typically represent 5–15% of the total round size — so on a $30M Series B, a founder might sell $1.5M–$4.5M of personal shares. Boards generally approve it when the selling founder retains at least 20% post-transaction and commits to a new 2–4 year vesting schedule.
Q: Does selling shares in a secondary affect QSBS eligibility? A: Yes — selling QSBS-qualified shares before a 5-year holding period voids the federal capital gains exclusion entirely for the shares sold. A founder who sells $2M of shares at Series B in year 3 loses the QSBS exclusion on those specific shares, creating a capital gains tax bill of $400k–$600k that could have been zero with one more year of holding. Work with a tax advisor before agreeing to any secondary terms.
Q: When do secondary funds buy founder equity and what do they want in return? A: Dedicated secondary funds typically purchase founder equity between Series C and pre-IPO at a 5–20% discount to the latest primary round price. In exchange, they typically require information rights, pro-rata participation rights in future rounds, and sometimes a board observer seat — rights that become permanent features of the cap table and can complicate future governance.
Q: What is a tender offer and when is it used instead of a direct secondary? A: A tender offer is a structured process where the company or a lead investor makes a formal offer to buy shares from multiple employees and shareholders simultaneously, typically with a 20–30 day window for acceptance. It is used when secondary volume exceeds 15–20% of the round size, or when the company wants to provide liquidity to a broad group including early employees and angels — not just founders.
Q: How does a founder secondary affect the Series C fundraising process? A: Modest secondaries (under 10% of round) executed at Series B rarely affect Series C fundraising if the founder retains strong ownership and re-commits via a new vesting schedule. Large secondaries or repeated transactions — especially those at a discount to round price — signal reduced founder conviction to incoming Series C investors and can reduce both valuation and terms quality in the next round.
