Diameter Pay Secures $10 Million to Widen US Dollar Access Globally

Diameter Pay, a FinTech platform that facilitates global US dollar payments and virtual accounts, has secured $10 million in Series A funding. The financing was co-led by CMT Digital and Lightspeed Faction, with participation from SixThirty Ventures, Stellar Development Foundation, Tech Council Ventures, Onigiri Capital, and BitRock Capital.

The company's technology enables banks, FinTechs, digital asset exchanges, and their end customers to access US dollar accounts and payment rails through a single API. It supports virtual accounts, domestic and international transfers, stablecoin on- and off-ramps, and embedded compliance tools across several US banking partners.

Diameter Pay's platform has already processed over $10 billion in 2026. The company's founder and CEO, David Lighton, said, 'The world is becoming more global, but the financial system is becoming more fragmented.' He added that Diameter Pay provides technology, data, and compliance infrastructure to understand and manage risk with greater precision.

The new capital will help Diameter Pay expand its push to widen access to the US dollar for financial institutions globally. The funds will be used to broaden its banking and payment functions, strengthen its stablecoin and foreign exchange infrastructure, and continue building technology and compliance capacity.
