Vignette is acquiring white label video provider Vidavee for $6.6 million. The sale is a testament to how competitive and difficult this space is, as the final price comes in below the $8 million that NYC-based Vidavee has raised. The company hasn’t done much to stand out from the pack, and its website currently suggests that it’s undergoing some sort of a refresh — though that could just be a reflection of the sale. The company, which (like a lot of others) helps companies add user-gen capabilities, has done online video work with the HuffingtonPost. The acquisition also underscores the fact that white label social start-ups, despite the trendy patina of Web 2.0, are very much within the enterprise software family. Release.
