Do you remember venerable VCBuzz? It was the by far best and most extensive deal database for venture capital fundings. It has left us last year - interestingly Jupiter Media who provided it has not only ceased to update the site but also removed all old entries as well.

However Patrick has pointed me to TechDealmaker a site that covers all M&A Deals. Not all VC fundings covered like VCBuzz but the site seems pretty much up to date. Alas you expected it - you will need a (paid) login for accessing most of the deep links...
