Can an ex-employee sell startup shares?

You left the company — or were let go — years before any exit. Do you still own anything, and can you turn it into cash? Usually yes, with a few conditions worth understanding.

Still holding options you never exercised? First check what exercising will cost — the strike price plus any tax — because that's the cash you need before there are shares to sell.

Plenty of people build real value at a startup, move on, and assume their equity is either gone or frozen until some far-off IPO. Often it's neither. Whether you can sell comes down to what you actually hold and what your paperwork says.

Do you still own anything after leaving?

• Shares you already exercised and paid for — these are yours. Leaving doesn't take them away (barring unusual clawback terms). They can typically be sold, subject to the company's transfer rules.
• Vested options you never exercised — here's the catch most leavers hit. Vested options usually come with a deadline to exercise after you leave — a post-termination exercise window. It's often around 90 days, but it varies a lot and some European companies extend it. Miss the window and the options can simply expire. Check your agreement now, not later.
• Unvested options — these almost always lapse when you leave. Nothing to sell.

What still has to be cleared

Being a former employee doesn't remove the normal restrictions on selling private shares:

• Right of first refusal. The company or its investors may have the right to buy your shares before an outside buyer can. You offer the shares first; if they pass, you're free to sell.
• Board or company approval. Many shareholder agreements require it for any transfer.
• Permitted buyers. Sales are often limited to experienced private investors who self-certify, rather than the general public.

The cost and tax you should check first

Exercising isn't free — you pay the exercise price, and in some countries exercising can trigger a tax charge even before you've sold anything. That combination (cash to exercise + a possible tax bill) is exactly why many leavers want to sell soon after: to cover the cost and lock in some value. Our free calculator shows the rough exercise cost and paper gain in seconds; the tax treatment depends on your country, so take local advice.

The Europe angle

Post-termination windows, exercise taxes and transfer rules all differ by country across Europe — there's no single rulebook. What's consistent is that there's no easy path for a former employee with, say, €40k of shares to sell. That's the gap we fill — with plain-English guides and a preparation toolkit that walk you through valuing your stake, the transfer rules and the tax, so you're ready.
