If you’re thinking of investing in a new technology company, maybe you should consider asking yourself, “What would Jeff Fluhr do?”

Fluhr is one of the co-founders of StubHub, and he served as its CEO from the beginning in 2000 to 2007 when the company was sold to eBay for just over $300 million.

And this week, Inc. magazine named ModCloth, one of the companies Fluhr invested in after leaving StubHub, the second-fastest growing private company in the U.S. with staggering growth over the past three years of 17,191 percent. Earlier in the year, the company was also named one of Ernst & Young’s entrepreneurs of the year.

Fluhr joined Pittsburgh-based ModCloth, an online women’s clothing retailer that specializes in retro or vintage-influenced fashions, as one of its directors after making an angel investment in the company in 2008. In its recent round of fund raising earlier this summer, ModCloth hauled in a total of $19.8 million.

ModCloth was started in 2002 by former Carnegie Mellon students Eric and Susan Koger, who married in 2006 after graduating. The company now employs 100 people full time, and its 2009 revenues were about $15.6 million.

In recent years, Fluhr also has invested in Invite Media, Twilio and Paperless Post, among others.

“I tend to invest in companies that have some user traction and ideally some revenue,” Fluhr told AngelList. “I understand e-commerce and the marketing analytics that go into customer acquisition and lifetime value.”
