The firm, founded by René Schoenmakers and Marco Jansen to trade comic books in 2008, has expanded to cover a variety of categories, from antiques through to jewellery, cars and wine.
Sales of 'crowdsourced' lots listed by multiple vendors are held across each week (beginning and ending on a Friday afternoon) with the site taking commission fees of 9% from the buyer and 12.5% from the seller when a lot reaches its reserve.
Catawiki say they vet their vendors and periodically inspect merchandise to ensure it is authentic.
As it stands, the site has a long way to go before it becomes the 'high-end eBay' its investors envisage, but this very significant injection of cash at least allows for that possibility.
