Vimeo is owned by IAC, the $9 billion dollar market cap company that owns Match.com, Tinder, OKCupid, Dictionary.com, and lots of others[0]. I don't think this is proof that Vimeo's revenue model is working out unless it's clear that this is being funded by Vimeo revenues and not just the broader IAC war chest.
