AOL is public again — sort of. Its owner Bending Spoons, the 13-year-old Italian company that has been quietly acquiring beloved but ailing internet brands for the past decade, went public on the Nasdaq today, opening at an over $18 ​billion valuation, with the stock then popping 40% by market close.

Headquartered in Milan, Bending Spoons applied some of the private equity playbook to a long series of acquisitions — Meetup, Eventbrite, Vimeo, WeTransfer, and many others. But it is not a flip-and-sell scheme: It wants to transform these companies with tech and then hold on to them.
