Socure said on Tuesday it had raised US$450 million in fresh capital from investors led by Accel and T. Rowe Price, valuing the digital identity verification startup at US$4.5 billion. Other venture investors including Bain Capital Ventures, Tiger Global, Commerce Ventures, Scale Venture Partners and Sorenson Ventures also participated in the latest round. The latest financing makes Socure one of the most richly-valued ventures in the digital verification sector, whose growth has surged during the pandemic as companies worldwide rolled out remote working operations for employees.
