Just had this email from Crowdcube:
We’re excited to announce the launch of Cubex, our marketplace for buying and selling shares in Europe’s high-growth businesses.
Cubex will give you the opportunity to tell us which private European businesses you’d like to buy shares in or sell your existing stake, creating liquidity and the chance to realise a return on your investment without having to wait for an IPO or trade sale.
We’ve already managed secondary share sales for the likes of Revolut, BrewDog and Freetrade [and monzo], with shareholders having the chance to realise over £16m in returns.
(When I registered interest it presents monzo as one of the companies I could invest in)
