Why Homophily Matters in Investing

According to Wikipedia, homophily (i.e., "love of the same") is the tendency of individuals to associate and bond with similar others. The presence of homophily has been discovered in a vast array of network studies. Within their extensive review paper, sociologists McPherson, Smith-Lovin and Cook (2001) cite over one hundred studies that have observed homophily in some form or another. These include age, gender, class, organizational role, and so forth.

Homophily matters for investing in start-ups, too. Women entrepreneurs get 15% of angel investments and also represent 15% of angels. Likewise, women entrepeneurs receive 6-10% of venture investments and represent 7% of venture capital investors.

I went to the Game Developer's Conference a couple weeks ago and met several game developers, who all proudly showed me their latest game on their iphones. The men showed me casual games themed with toy canonns and monsters and the women showed me carbon-eating sprites and earnest children's games. While I loved the energy of each of the game developers that showed me their games, I was more interested in the potential for the games that my niece likes to play. And, in the end, it's women who are the buyers in casual gaming.
