Andrey Andreev
Rank 2017
Moscow-born Andreev, 43, founded Badoo, a dating network site that has more than 340m users, with 400,000 new ones signing up daily. While Tinder is bigger in the UK, America and Australia, Badoo’s hotspots include South America, South Africa, Spain and eastern Europe. It is free to use but charges members who want to boost their visibility to other people seeking a date.
   In 2015 the London-based tech entrepreneur teamed up with Whitney Wolfe, a co-founder of Tinder, to launch Bumble, a platform aimed specifically at women, which now has at least 3.5m users. When he was 18 Andreev studied management at Moscow University but dropped out after 18 months and moved to Spain where his parents had relocated. He soon set up a string of successful internet start-ups such as the Russian dating site Mamba, web-tracking business SpyLog and Begun, an advertising firm.
   Badoo, founded in 2006, was valued at £190m a year later, rising to £1.2bn in 2013. It has been profitable since 2009 and has reported revenues of $200m a year. In 2014 Andreev told a Russian newspaper that his goal was to “take over the American market”. He and his management team have an 80% stake.
