Funds will expand AI agent Primer Companion and drive US growth.
US revenue, currently one-fifth of the total, is targeted to exceed one-third by 2028.
Primer, the London-based payments infrastructure company, has closed a $100 million Series C funding round, taking its total capital raised to $170 million. The round was oversubscribed and led by Sofina, the Belgian investment group, with Peak XV Partners joining alongside a roster of returning backers: Balderton, Accel, ICONIQ, Tencent, and Speedinvest.
The company, founded in 2020 by Gabriel Le Roux and Paul Anthony, both alumni of Braintree, the Chicago-based payments gateway that PayPal acquired in 2013 has built what it describes as a unified infrastructure layer for global enterprise payments. Its platform sits across the full transaction lifecycle, from checkout to payout, consolidating the fragmented web of processors, acquirers, fraud tools and payment methods that large merchants typically rely on.
