How to sell startup shares in Europe

Updated 2026-10-26

You can usually sell shares in a private startup, but not freely. The company’s articles and shareholder agreement decide who may buy, who gets asked first and who must approve. Buyers pay less than the last round price in most cases. A clean sale takes a few weeks to a few months.

This guide covers the steps in order: what you own, what the documents allow, who buys, how a price is set, and how the transfer closes.

Can I sell my startup shares?

It depends on what you hold.

• Ordinary or preferred shares. You own them, so you can sell them, within the transfer rules below.
• Vested options. You can sell them only after you exercise them into shares, unless the plan allows a transfer. Check the exercise window too: many plans give leavers 90 days or less.
• Virtual shares (VSOPs, phantom shares). These are a cash promise from the company, paid at an exit. There are no shares to transfer, so they cannot be sold. A company buyback is the only route before an exit.
• Leaver clauses. If you left the company, a bad-leaver clause can force you to sell back at nominal value. Read it before you plan a sale.

Read the transfer rules first

Two documents set the rules: the articles of association and the shareholders’ agreement. Look for:

• Right of first refusal or pre-emption. Existing shareholders, or the company, get to buy at the price you agreed with an outside buyer before that buyer can.
• Consent. Many agreements require board or investor approval for any transfer.
• Lock-ups and permitted transferees. Some agreements block transfers for a period, or allow them only to family trusts or affiliates.
• Tag-along and drag-along. These matter when a larger sale is under way.

Formalities differ by country. In Germany, transferring GmbH shares requires a notarised deed. In the UK, a stock transfer form and stamp duty of 0.5% on the price apply above a small threshold. A local lawyer can confirm the steps in a short call.

Who buys startup shares

• Existing investors. They know the company and often hold a right of first refusal. Ask them first.
• The company. A buyback is possible when the company has the cash and the legal reserves to pay for it.
• New investors in the next round. Some rounds include a secondary part, where a new investor buys shares from early holders alongside the new money.
• Angels and syndicates. At seed and Series A, individual angels and syndicates are the main outside buyers for smaller stakes. AVA Ventures buys stakes of $25k–500k at any stage.
• Secondary funds and platforms. These focus on later-stage companies, usually Series B and beyond. Below that, a market barely exists.

How buyers price a stake

Buyers start from the last round price and apply a discount for:

• Share class. Ordinary shares and options sit behind the investors’ liquidation preference, so they sell for less than preferred shares.
• Stage. Early stakes have few buyers and a long wait to exit.
• Age of the last price. A round from three years ago says little about today.
• Progress. A company ahead of plan can sell at the last price or above. One behind plan sells far below it.

For late-stage companies, discounts to the last round averaged about 8% in early 2026, and a third of trades closed at a premium. For ordinary shares in younger companies, 20–40% below the last round is common, and more for seed-stage stakes. The startup equity calculator turns these factors into a range for your stake.

The steps to sell private company shares

1. Collect your documents. Share certificates or the register entry, your option agreement, the articles and the shareholders’ agreement.
2. Talk to the company. Founders and CFOs prefer to hear about a sale early. They can tell you who has a first-refusal right and whether a buyback or a planned round could help.
3. Find a buyer and agree a price. Expect questions about revenue, growth and the cap table, which the company may need to approve sharing.
4. Run the first-refusal process. Offer the stake to the holders of the right at the agreed price. If they pass, you can sell to your buyer.
5. Sign the transfer. A share purchase agreement, plus the local form: a notarised deed in Germany, a stock transfer form in the UK.
6. Register and get paid. The company updates its register, and the buyer pays.

Tax

Gains on shares are usually taxed as capital gains where you live. Shares or options you received as an employee can be taxed as income on exercise or on sale, and the rules vary by country and by plan. Ask a tax adviser before you sign.
