A common belief is that U.S.-born
tech founders of technology
companies tend to be young.
We found that about 1 percent
were teenagers when they started their firms.
More than twice as many were older than
age fifty than were younger than twenty-five.
Many, in fact, were in their sixties when they
founded their startups.
The vast majority of U.S.-born tech
founders were older than twenty-five.
The average and median age of key tech
founders was thirty-nine.
