Marc Andreessen on Yahoo's new CEO

"Very exciting for the Valley."

FORTUNE -- Venture capitalist Marc Andreessen believes that Marissa Mayer is a smart choice to run Yahoo Inc. (YHOO), according to comments made today during Fortune Brainstorm Tech in Aspen.

He said that while he is a big fan of Yahoo interim CEO Ross Levinsohn-- who many believed would get the fulltime job -- the selection of Mayer indicates that Yahoo wants to be a product-centic company, rather than a media/sales-focused company.

"I'm very happy for Marissa, and it's very exciting for the Valley," he added.

Andreessen last year worked with private equity firm Silver Lake to explore a takeover of Yahoo, and there even were (unfounded) suggestions that he might assume a senior operating role.
