Boston-based financial services technology startup Numerated has nearly doubled its total funding with a new $15 million round, and now plans to expand its offerings for commercial banking clients and to enter the realm of consumer transactions. It’s been more than two years since Numerated spun out of Eastern Bank into a standalone company. The business started inside the bank as Eastern’s internal technology incubator, but three years later, CEO Dan O’Malley and a team of employees struck out on their own.
