Andreessen spotted alone

A fan spotted Marc Andreessen walking alone, probably coming back from picking up his mail at the end of his several mile long driveway, on the afternoon of September 27, 2026. Was he all alone? “Definitely yes,” says the fan, adding that “He was wearing a large sweater and looked really cute!”

Is Marc back on the market?

A rep for Marc Andreessen was not immediately available for comment.

Truth or rumor, when news that the business man was splitting hit the internet Monday (September 28), Twitter immediately exploded with pithy commentary. It seems everyone had an opinion on the matter:

“Has anyone Marc’s phone number?”

“So very sad… Those 2 were so great as a couple. So cute together.”

Based on the facts (Andreessen spotted alone with a cute sweater), is there trouble in paradise or is it much ado about nothing?
