STAK
How a STAK holds shares and issues certificates.
Holders place sealed orders on the dates you set. Every filled order trades at one clearing price, and one SEPA file pays the sellers.
In beta today: every holder sees the AFM notice and can open a list of five risks.


Your employees hold certificates (depositary receipts) from a STAK, the foundation that holds the shares, with no public place to sell them.
The company or its STAK buys from sellers and sells to buyers at one price.
Set the dates, price rule, holder limits and any buyback budget. The default price is your latest valuation.
Youdates you choose
On any device, holders choose buy or sell, a number and, unless the price is fixed, a price.

When ordering closes, the platform finds one price and who gets what. You send it, and every holder gets an email.

Buyers pay through your own payment provider or by bank transfer, and you mark transfers as paid.

Tulpwerk is our demo company, so the numbers are made up and the screens are real.
Sanne set a range of 2.40 to 9.60 euros around the 4.80 euro valuation, capped each buyer at 5,000 certificates and set aside 10,000 euros for buybacks.

Lotte can change or withdraw her order for 1,000 certificates until ordering closes. Sellers confirm their IBAN with a one-cent iDEAL payment or a bank statement.

After a rehearsal of Tulpwerk's day, Sanne exports the SEPA file and completes the day, which the platform won't clear twice.

No, only current certificate holders can take part, on the days you set. Buyers pay your company and your bank pays the sellers, so the money never passes through Share Council. Your adviser can tell you whether an AFM exemption applies.
Sellers keep their certificates, unless the company set a buyback budget. When supply and demand don't match, the platform scales back every order on the larger side by the same share.
You choose a fixed price, a minimum only, or a range. With a minimum or a range, the platform picks the price at which the most certificates change hands. If two prices give the same volume, the higher one wins.
It is an add-on on a paid plan, which certificates need too. You can't switch it on during the try-out, but you can look around for free first.
For setting up the STAK, yes. Shares in a BV move only by notarial deed, so the trading day is for certificates issued by a STAK and similar instruments. Share Council records those transfers when you complete the day.
