The Company helped monitor a total of 4.8 billion transactions, representing $693 billion in value, an increase of 5.2x year over year.
The round values San Francisco-based Unit21 at $300 million and comes nine months after the startup raised a $13 million Series A that included investments from the founders of Plaid, Chime and Shape Security as well as former Venmo COO Michael Vaughan.
Unit21 has grown substantially this year, with a 400% uptick in business within the past 12 months and new customers like Intuit, Coinbase, Gusto, and Line.
