Kongregate, the SF-based game community, has raised $3 million from Jeff Bezos’ Bezos Expeditions. The company, which allows developers to create and distribute their own games, says the funding will allow it to better scale the business and to improve the advertising side of the business. Last year, Kongregate announced a $5 million first round led by Greylock. That previous funding, the company said, would go in part towards bankrolling certain developers. Developers are paid a percentage of advertising revenue from the site, encouraging their participation. Release.
