Venture capital industry news site VentureBeat has purchased TradeVibes, a wiki info site on startups, which it is relaunching as its own startup directory site. The new site—VentureBeat Profiles—features capsule profiles on startups. Readers and the companies themselves can update basic information, submit press releases, and also explain why they’re ‘bullish’ or ‘bearish’ on the businesses (VentureBeat Editor-in-chief Matt Marshall has more on how it works here).

It’s in an increasingly competitive startup directory space. TechCrunch has its own directory, Crunchbase, as does startup site ChubbyBrain, which launched in beta in February and says it’s already the “largest startup and investor database on the web.”

No terms of the deal were announced, although TradeVibes had raised $900,000 in a seed round a year ago. Venturebeat, meanwhile, raised $320,000 in a seed round in February 2008.
