A St. Petersburg drone analytics company has received $3 million from a Boston-based venture fund. 5x5 Technologies announced the raise will be part of a larger $6 million Series B funding round, led by Boston-based Safar Partners Fund. The company will also join 5x5 Technologies board of directors. A Series B is typically a larger raise than a Series A round, which is a company's first foray into a large funding round.
