Dutch company Catawiki, which puts auctions on the Internet, is announcing today that it has raised $12.8 million in new funding led by Accel Partners. Project A Ventures, Arthur Kosten, and Willem Sijthoff also participated.

Along with helping buyers discover new items, it also smartly leverages professional auction experts for curation and supervision and provides high-quality weekly auctions. Catawiki’s auction experts advise sellers on price and presentation and answer buyers’ questions.

Catawiki gets 3 million monthly unique visitors and has 35 categories of items.

The company will use the funds to expand throughout Europe, add more auction categories, and grow its marketing team.
