Law firm Cooley today released its latest report showing what it called a “solid start” for venture capital fundings during the first quarter of 2010.

The report is based on the 83 deals that Cooley was involved with, so it’s less comprehensive than the MoneyTree report or the data from VentureSource. But Cooley can compile details beyond the money raised and the round of funding.

For example, one of the most encouraging signs was a continued increase in the number of “up” rounds, where the valuation increased from the previous round. That number tumbled to 16 percent during the first quarter of last year, and now it’s up to 58 percent. And there were seven deals where the valuation was more than $100 million.

On the other hand, there were some numbers that held flat or dropped. Pre-money valuations for first round fundings (Series As) only increased slightly, while second and third funding valuations dropped. The biggest increase was in later-stage fundings — Series D or later.
