Investments by venture capital firms rose sharply in Massachusetts and the nation last year, returning to the levels achieved before the economic crisis of 2008, according to a report released yesterday by CB Insights, a New York venture capital database.
After a third quarter that the report categorized as “blah,’’ Massachusetts recovered in the last three months of 2011, with a 35 percent increase in venture funding and a 12 percent increase in the number of deals over the previous quarter.
