Zynga puts San Francisco headquarters on the market

Things continue to look distinctly unhealthy for former social gaming giant, Zynga.

According to VentureBeat, Zynga has confirmed a report fromlocal blog SFist that the social firm was selling its San Francisco HQ (pictured).

The blog also reports that the property is 670,000 square feet and according to San Francisco real estate site The Registry, was purchased in 2012 for $228 million.

Back then, the site was worth $340 per square foot – now the social firm will see $800 per square foot. This means roughly a $536m sale.

VentureBeat also writes that Zynga claims it announced its intention to sell its base in its Q4 conference call – though much like VentureBeat, we can’t find record of that, either.

Having risen to prominence on the back of social game FarmVille, Zynga’s business hasn’t been all too healthy for years now. Execs have been departing the firm for years now, including CEO Don Mattrick, and it shed 18 per cent of its workforcelast year.

That’s on top of dwindling user numbers, but recently its losses narrowed.
