Women lead less than 7 percent of venture-backed startups, yet there are more women in senior positions at successful startups than at unsuccessful ones, according to a Dow Jones study cited by Bloomberg. If you combine this with a 2011 study showing that tech companies started by female entrepreneurs have higher returns per capita on average, it seems like startups founded by females are the way to go.

Alisa Chumachenko founded Game Insight International in Moscow in 2010.
