On a recent morning, a half-dozen young software engineers hunched over laptops at The Cup, a café on bustling Pearl Street in downtown Boulder. They were holding an informal meeting about a social networking app they're developing and seemed to be on a first-name basis with the parade of techies walking through the door.
An influx of entrepreneurs like these has changed the face of this Colorado city of 98,000, making it a destination for Internet startups. With the University of Colorado as an anchor and a backyard full of mountains as lifestyle bait, Boulder now has the highest concentration of software engineers per capita in the nation. It's second only to Silicon Valley in percentage of workers employed in tech, according to the American Electronics Assn. Best-selling author and urban development expert Richard Florida says it has the greatest concentration of the "creative class"—scientists, artists, engineers, and the like—in the U.S.
The university and prestigious research labs such as the National Center for Atmospheric Research and the National Institute of Standards & Technology have long attracted well-educated folks to Boulder. In the 1970s, Celestial Seasonings and StorageTek helped foster a robust natural foods industry and a thriving tech community. Over the years, software, data services, and biotech blossomed as employees of those companies branched out to pursue other interests. The combination of entrepreneurship, engineering talent, and a counterculture vibe gave rise to many pre-bubble Net startups.
