Most founders spend an enormous amount of time learning how to raise money. They learn how venture capital works, how term sheets work, how dilution works, and how to tell a compelling story to investors. What they often don't spend much time learning is how they might someday turn some of that stock back into actual money.
‍

That's understandable. During the early years of a startup, liquidity feels like somebody else's problem. You're worried about product development, customer acquisition, hiring, fundraising, and survival. Worrying about how you might someday sell shares feels almost arrogant, as though you're counting money that doesn't exist yet.

Then something interesting happens.

The company starts working.

A few financing rounds go by. The valuation grows. Friends and family begin assuming you're wealthy. You may even start believing it yourself. Then one day you discover a peculiar characteristic of startup stock: you can own millions of dollars of it on paper and still find yourself debating whether it's financially responsible to replace a fifteen-year-old car.

This is where founders begin learning about secondary markets.

In its simplest form, a secondary transaction is just the sale of existing shares from one shareholder to another. No new shares are created. No money goes into the company. Ownership simply changes hands. Think of it this way: when investors participate in a financing round, they're usually buying newly issued shares directly from the company. That's called a primary transaction. When a founder, employee, or investor sells existing shares to another buyer, that's a secondary transaction.

Historically, secondary transactions weren't a particularly important part of the venture ecosystem because successful startups either got acquired or went public relatively quickly. If you expected liquidity within four or five years, keeping all your chips on the table wasn't an unreasonable decision.

Today's startup environment looks very different. Companies routinely remain private for a decade or more. The average exit is now 11 years after founding. As a result, secondary markets have evolved from a niche corner of venture capital into an increasingly important source of liquidity for founders, employees, and investors alike.
‍

This isn't just a theoretical trend. PitchBook's latest research shows secondary transactions continuing to grow as private companies stay private longer and shareholders look for ways to create liquidity before an acquisition or IPO finally arrives. It's already over $100B a year in transactions, and growing fast. The startup world has quietly been building its own liquidity ecosystem because the traditional exits are taking much longer than they once did.
‍

For founders, this matters for a very simple reason: concentration risk.
‍

One of the stranger cultural norms in venture capital is the belief that founders should remain financially terrified for as long as possible. Investors diversify. Limited partners diversify. Wealth managers spend entire careers explaining the virtues of diversification. Yet when a founder suggests selling a small portion of their stock, the conversation can suddenly shift from finance to morality.

I've never found that argument particularly persuasive.

A founder who owns twenty percent of a company worth $100 million may have a paper net worth of $20 million, but paper wealth doesn't pay mortgages, fund college educations, or reduce the stress that comes from having every important financial outcome in your life tied to a single illiquid asset. I've known founders who looked wildly successful from the outside while privately carrying levels of financial stress that bordered on absurd. Every major life decision became entangled with the future outcome of the company. Should we buy a house? Depends on the company. Should we move closer to family? Depends on the company. Should we have another child? Depends on the company.
‍

At some point that's no longer entrepreneurship. It's concentration risk.

This is why many founders eventually explore a secondary sale. A modest liquidity event can eliminate debt, establish financial security for a family, fund college savings accounts, and remove a tremendous amount of pressure from future decision-making. In many cases, it actually makes founders better CEOs because they're no longer making every decision with one eye on their personal bank account.

Unfortunately, this is also the point where many founders discover that finding a buyer is often the easy part.

The hard part is getting permission. Don't ignore the relevant clauses in your Series A term sheet negotiations.
