Bird is a private communications company headquartered in the Netherlands. If you hold vested shares or options in Bird and want to turn part of that into cash before an IPO or acquisition, this is a plain-English guide to how a private secondary sale actually works — and what's specific to Bird and to the Netherlands.

Independent guide. PrivateTechShares is not affiliated with, endorsed by, or connected to Bird. This is general educational information for people who already hold Bird shares or options. Always check your own share/option agreements and take professional advice. We do not recommend or endorse any transaction: whether to buy or sell, and on what terms, is entirely the individual decision and responsibility of the buyer and seller, based on their own due diligence. What we do: we help you prepare — a clear picture of what you hold, what it may be worth, and the paperwork — so that when you decide to act, you are ready.

Can you sell Bird shares before an exit?

Often, yes. Selling existing shares you own in a private company to a private buyer, before the company is sold or lists, is called a secondary sale. It's possible for Bird shares if they're vested and transferable, and once you've cleared Bird's transfer rules. There's no public market for a private company, so a sale is a private, negotiated transfer — not a click of a button.

What you probably hold

First, pin down what you actually have. In the Netherlands, startup equity is usually held as depositary receipts (certificaten) via a STAK, or options. You can generally only sell shares, so if you hold options you typically exercise them (pay the strike price to convert them into shares) before you can sell. Check your grant documents for your vested amount, strike price and any deadlines.

The rules that apply in the Netherlands

How a sale works, and how it's taxed, depends on the rules in the Netherlands — transfer formalities, any right of first refusal, and the tax on a gain. We've written a dedicated plain-English guide: selling startup shares in the Netherlands. Read it alongside this page.

Who buys Bird shares

There are four realistic buyers, roughly in order: Bird itself (if it runs a buyback or tender), existing investors or shareholders (often via a right of first refusal), the investor in Bird's next funding round, and — when those don't apply — a private individual investor who wants exposure to Bird. Recognisable names like Bird tend to attract private-investor interest — but the hard part for a holder is understanding what you actually own, what it might be worth and how a private transfer works. That's what our guides and toolkit are for.

What to expect on price

A private, minority, all-cash secondary usually happens at a discount to Bird's last headline valuation — because the buyer takes an illiquid stake with no guaranteed exit, and because you likely hold common shares, which are worth less than investors' preferred shares. That's normal, not a trick. See what discount is fair for a realistic range.

Thinking about selling your Bird shares?

Exercising, holding or selling equity is usually a one-way decision. Doing it well takes a real assessment — what you hold, what it's realistically worth, the transfer rules that apply, and the tax. The equity toolkit is exactly that homework in one place: the free tools give you the numbers; the toolkit turns them into a decision you can stand behind.

Questions people ask

Can I sell my Bird shares before an exit?

Often yes. If you hold vested, transferable shares in Bird you can sell them to a private buyer in a secondary before an IPO or acquisition, subject to Bird's transfer rules — typically a right of first refusal and board or company approval. If you hold options rather than shares, you generally exercise them into shares first. Bird is a private company, so there is no public market; a sale is a private, negotiated transfer.

How much are my Bird shares worth?

There is no live price for a private company like Bird. A rough estimate starts from the price per share at its most recent funding round, adjusted for your share class (common shares are usually worth less than the preferred shares investors hold) and a discount for selling a private, minority, illiquid stake. Use our free valuation estimator as a starting point, and remember it is only an estimate.

Who buys Bird shares?

Four types of buyer: Bird itself (via a buyback or tender, if it runs one), existing investors or shareholders (often via a right of first refusal), the investor in an upcoming funding round, or a private individual investor seeking exposure to Bird. Well-known names often attract private-investor interest, which is why it helps to understand your shares and how a private transfer works before you start.

Do I need Bird's approval to sell my shares?

Almost always, yes. Bird, like most private companies, controls share transfers through a right of first refusal, transfer restrictions and board or company approval written into your equity documents. No marketplace or buyer can override that. Start by reading your grant and shareholder agreements and asking Bird's stock administration what is permitted.

What tax will I pay when I sell Bird shares or stock?

It depends on where you live and what you hold. In the United States, selling settled shares usually triggers capital-gains tax, and exercising options first can create a separate taxable event (including AMT on ISOs). In Europe the treatment varies by country. This is general information, not tax advice — confirm your own position with a qualified adviser before you sell.
