Microsoft To Buy Powerset? Not Just Yet.

VentureBeat is reporting that Microsoft has agreed to buy semantic search engine Powerset for somewhere around $100 million, which is the price we previously reported was being offered to the company.

Our sources have been saying this deal is highly likely since May, but hasn’t actually been signed yet and could still be disrupted by the ongoing Microsoft-Yahoo negotiations. Dave Wehner, a Managing Director at investment bank Allen & Co. (he’s the guy who sold Bebo for $850 million to AOL), is representing Powerset in the deal.

Powerset debuted at TechCrunch40 last fall and opened a showcase of its technology to the public just last month.

Powerset has raised around $12.5 million in venture capital, and is rumored to have taken another $8 million or so in convertible debt as bridge financing.
