Rumors about Google acquiring RSS management company Feedburner from last week, started by ex-TechCrunch UK editor Sam Sethi, are accurate and are now confirmed according to a source close to the deal. Feedburner is in the closing stages of being acquired by Google for around $100 million. The deal is all cash and mostly upfront, according to our source, although the founders will be locked in for a couple of years.

The information we have is that the deal is now under a binding term sheet and will close in 2-3 weeks, and there is nothing that can really derail it at this point.

Huge congratulations to Feedburner. The company was founded in 2003 and has raised just $10 million in capital over two rounds. Portage Ventures funded their $1 million Series A round in 2004. The $9 million Series B round was closed in mid 2005 (second close in 2006), from Mobius Venture Capital and Union Square Ventures.
