Andrew Busey has been a part of some key web technologies over the past 15 years, such as Mosaic (the first web browser) and iChat (one of the first IM apps). He also co-founded Pluck.Yet, Busey's passion is gaming. So, a couple years ago, he started a new company in the space: Challenge Games.
In fact, this week the firm raised $4.5 million from Sequoia Capital (keep in mind that the firm has invested in such break-out companies like Atari, Electronic Arts and nVidia). The venture capitalist on the deal, Roelof Botha, learned about the company while playing its popular title, Duels.
