WSJ’s Tech Blog recently published a profile of the ‘typical’ tech entrepreneur, based on a survey by the Kauffman Foundation. Here are the typical characteristics:

• founded their $1,000,000-plus company, on average, at 39 years of age
• more than 90% have completed a college degree
• four times as likely than the general public to have attended an Ivy-League university
• spending an average of 16.4 years in employment, prior to founding their startup company
• only 37% have computer science or engineering degrees, and 3% have liberal arts degrees

The entrepreneurs surveyed were executives of companies started between 1995 and 2005 heading up companies with revenues of at least $1 million. http://tinyurl.com/4bzdld (Wall Street Journal Online — subscription required).

Interesting to me: no mention of the gender breakdown. While the Bill Gates stereotype of the ’20-something college dropout who strikes cyber gold in his garage’ is apparently dead-wrong, I’d be interested to know whether the stereotype of the relative scarcity of women entrepreneurs is dead-right.
