Fab.com, previously backed by US news provider Washington Post, raises $40m only five months after it reportedly raised $8m in its Series B.

Venture firm Andreesen Horowitz has led Fab.com to a $40m round today, although prior backer the Washington Post is not mentioned in the latest announcement.

Fab.com said other participants in the series B round were Menlo Ventures, First Round Capital, Baroda Ventures, SoftTech VC, movie star Ashton Kutcher – Guy Oseary, former chairman of music label Maverick Records, and A-Grade Investments. 

Fab.com, which now sells design items, but started out as Fabulis, the gay social network, raised $8m in July, according to news provider TechCrunch. The Series A funding was led by Menlo Ventures.
