To do that, she'll need money, and the wealthy Russian who just slid into her inbox has plenty of it.

So they set a meeting.

And when they finally sit down together, it won't go the way either of them expects.

It's late summer 2014.

With her lawsuit against Tinder still ongoing, Wolf heads to Europe to visit her sister, who's studying at a culinary school in Paris.

But first, she makes a side trip to London.

When she arrives, she heads to a glass and steel office tower to meet with Andrei Andreev, the Russian who emailed her out of the blue.

Andreev runs Badoo, a dating app company popular in Europe and Latin America.

He gives Wolf a tour of his company's offices and then makes his pitch.

Whitney, I love your passion and energy.

I've watched what you did at Tinder, and I think you should join Badu as our chief marketing officer.

Wolf eyes Andreev skeptically and then crosses her arms defiantly.

Andreev doesn't give up.

What kind of company are you building?

Andreev can tell she's serious.

He's disappointed he can't nab Wolf for Badoo, but he likes the sound of a social brand that caters to women.

So instead, he suggests they keep talking.

Over the next few days, the two take long walks together through London's parks.

Wolf pitches her vision, trying to get his financial backing, while Andreev keeps nudging her back toward the dating world.

In the end, they agree to a partnership.
