Why it happens
Every reason a secondary sale happens
"Secondary sale" covers a wide range of situations — a departing employee cashing out vested stock looks nothing like an institutional LP selling a fund stake, but both run on the same underlying mechanics covered in how a deal works. Here's who initiates a secondary transaction, and why — each with a worked numeric example.
Employees & founders
Employee & founder liquidity
The most common driver. Equity compensation vests over years, but a company staying private for a decade or more means that value stays on paper the whole time. Employees sell a portion of vested shares — through a company tender offer or a private sale — to cover taxes, buy a home, or simply diversify a net worth that's overexposed to one employer's stock.
Early investors & angels
Early investor & angel liquidity
An angel or seed fund that wrote a check years ago is often the most price-insensitive seller in the market — any exit at a meaningful multiple looks good relative to the tiny entry price. These sellers use secondaries to de-risk a concentrated bet, return capital to their own backers, or simply free up time and attention from a company they no longer actively support.
LPs in venture & PE funds
LP liquidity in fund structures
Limited partners in a venture or private equity fund can't just sell 'the fund' on an exchange. Instead, an LP-led secondary sells their entire limited partnership interest — the remaining, undistributed value across the fund's whole portfolio — to a specialist secondary buyer, typically at a negotiated discount to the fund's reported net asset value. This is the largest single category of the global secondary market by dollar volume.
General partners
GP-led continuation vehicles
When a fund's life is ending but its manager still believes in one or two standout portfolio companies, a GP-led continuation fund lets the manager move just those assets into a new vehicle, backed by new secondary investors, while giving the original LPs a choice: cash out now, or roll their position into the new fund. It's become one of the fastest-growing structures in private equity precisely because it solves a timing mismatch — great companies, expiring fund clocks.
Growth & late-stage investors
Portfolio rebalancing for growth funds
A growth-stage fund that has ridden a company from Series C to a $10 billion-plus valuation may have a single position representing an outsized share of the fund. Trimming that position via a secondary sale — selling part of the stake to a new investor at the current valuation — locks in returns and reduces concentration risk without forcing an exit from the company entirely.
Individuals in personal transitions
Estate planning, divorce & personal liquidity events
Illiquid startup equity is still a real asset that has to be accounted for in a divorce settlement, an estate plan, or a personal bankruptcy. A secondary sale — sometimes of a very small position — converts that equity into cash or a clean, transferable asset so it can actually be divided, distributed, or valued the way any other asset would be.
New investors
Buying in without a primary round
Not every use case is about selling. For an investor who missed a company's early rounds — or who wants exposure to a company that has stopped raising primary capital at an accessible size — buying an existing shareholder's stake through a secondary transaction is often the only way in. This is the demand side that makes every use case above possible.
