Diameter Pay, a fintech platform focused on global U.S. dollar payments and virtual accounts, has announced a $10 million Series A financing round. The investment 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. Announced from Jersey City, New Jersey, the funding will support the company's effort to expand access to U.S. dollar accounts and payment rails worldwide.
Bridging Fragmented Payment Networks
Diameter Pay enables banks, fintechs, digital asset exchanges and their customers around the world to access U.S. dollar accounts through a single API. The platform supports virtual accounts, domestic and international payments, stablecoin on- and off-ramps, and embedded compliance controls across multiple U.S. banking partners. The company reports that it has processed more than $10 billion in transactions year-to-date in 2026.
Addressing Access and Compliance Pressures
The U.S. dollar remains the foundation of global trade and payments, but access has become increasingly difficult in many parts of the world. Correspondent banks have pulled back from entire markets amid rising sanctions and anti-money laundering risk, creating a system where legitimate businesses can be excluded alongside bad actors. Diameter Pay says it takes a different approach by providing technology, data, and compliance infrastructure to understand and manage risk with greater precision.
Founder's Vision for Faster Money Movement
David Lighton, founder and CEO of Diameter Pay, said the world is becoming more global while the financial system is becoming more fragmented. He explained that instead of asking banks to accept more risk, the company provides technology, data, and compliance infrastructure to understand and manage risk with greater precision. That approach, he said, builds a bridge between traditional finance and digital finance so money can move at the speed people and businesses need in a 24/7 world.
Stablecoin Connectivity and Regulated Rails
Stablecoins are amplifying the need for solutions because they allow dollar value to move globally around the clock. Institutions still need regulated, reliable connectivity between digital dollars and the U.S. banking system, especially to fight financial crimes. Diameter Pay provides that connective tissue, giving banks the tools to manage digital risk while bridging traditional finance and digital finance.
Investor Views on Trust and Modern Payments
Charlie Sandor, partner at CMT Digital, said stablecoins are transforming how dollars move globally but do not replace the need for trusted access to the U.S. banking system. Tim Khoury, partner at Lightspeed Faction, stated that the challenging part of modernizing global payments with stablecoins is building reliable compliance and banking infrastructure. Evan Thorpe, principal at SixThirty Ventures, added that trust, not transport, is the product in modern money movement and that Diameter delivers it.
Planned Use of Series A Capital
The financing will accelerate Diameter Pay's mission to expand access to the U.S. dollar for financial institutions around the world. The company will use the capital to expand its banking and payment capabilities, deepen its stablecoin and FX infrastructure, and continue investing in technology and compliance capabilities. These investments are intended to support the safe movement of dollars across borders at the speed businesses require.
Diameter Pay's Series A round signals growing investor confidence in infrastructure that connects traditional banking with digital asset rails and cross-border payments. By combining U.S. dollar accounts, stablecoin capabilities and compliance controls, the company aims to reduce fragmentation in global finance. As demand for always-on payments increases, its platform may offer regulated institutions a practical route to faster, safer international transactions.
