In three years, Krugle, the company behind the code search engine of the same name, has gone from an idea to a company that's starting to produce revenue. CEO Steve Larsen, a veteran of half a dozen startups, attributes this brief time to market as being due largely to free and open source software (FOSS). According to Larsen, FOSS has shaped most aspects of the company, including its hiring practices and relations with business partners and users.
