Biz Stone, the co-founder of Twitter who recently stepped away from the company to relaunch Obvious, has taken a role as strategic advisor at Spark Capital. According to Mashable, startups Spark Capital has invested in include Twitter, Tumblr, Foursquare, Boxee, Kik and Stack Exchange. Stone also runs the Biz & Livia Stone Foundation and is a strategic advisor at AOL.

Biz Stone, Evan Williams and Jason Goldman, men responsible for Twitter, plan to re-start their former company The Obvious Corporation. Obvious was a company they formed prior to Twitter’s fame, and abandoned in favor of focusing on Twitter. The reborn Obvious will, in Stone’s words, “help people work together to improve the world.” What that means, exactly, is unclear, but it sounds like it will be a source of innovative products. All three have stepped back or resigned from Twitter to return focus to The Obvious Corporation. [TechCrunch]

On February 20, ODEO wrote on their blog that they were looking for a new home. ODEO was owned by Obvious.com, who are the same creators of Twitter. Since Obvious is focused on Twitter and that company is doing very well, letting go of ODEO was not a very hard decision.

ODEO was acquired by SonicMountain, a New York based startup company. TechCrunch reported that the price was not disclosed, but the amount is above $1 million in cash. The founder of ODEO and Obvious.com, Evan Williams will be working at SonicMountain as an advisor for 6 months.

ODEO has had a rocky past. The company previously raised $5 million in funding from Charles River Ventures and a few other angel investors. After that, Evan Williams didn’t like the idea of having investors, so they bought the company back. The amount that they paid back for the company is rumored to be above the $5 million. Sometimes you make decisions and can’t look back. Congratulations to Obvious.com and SonicMountain.
