Diameter Pay, a stablecoin payments infrastructure startup founded in 2023 by former World Bank staffer David Lighton, closed a $10 million Series A co-led by CMT Digital and Lightspeed Faction. It is the company's first external round after years of bootstrapping, with the equity raised in a single tranche between April and July. Lighton declined to disclose post-money valuation.
The startup says it has processed more than $10 billion in payment volume year-to-date across more than 10,000 end users, servicing banks, fintechs and digital asset exchanges through sponsor bank partners Portage Bank and SSB Bank. A third sponsor bank, which Lighton described as a public company, has not been disclosed.
Why it matters
The thesis is the structural retreat of USD correspondent banking under sanctions and AML pressure, which Diameter Pay argues is locking legitimate businesses out of dollar access alongside the bad actors the safeguards target. The startup wraps stablecoin on- and off-ramps, compliance controls, and virtual USD accounts into a layer foreign fintechs and banks can plug into. Lighton said the founding vision came from his World Bank work in Haiti after the 2010 earthquake, where he focused on remittances.
The investor mix reads as institutional validation: CMT Digital took a board seat, Lightspeed Faction and SixThirty Ventures took observer seats, and former Fidelity Investments president Robert Pozen is a senior advisor. The Stellar Development Foundation's participation points to the cross-border thesis given Stellar's remittance heritage.
Market impact
Diameter Pay plans to deploy the capital to widen its sponsor bank roster, deepen stablecoin and FX infrastructure, and invest in compliance tooling for cross-border dollar movement. The team sits at roughly 20 people across the US, Argentina, Poland, and Nigeria, with active hires for CTO and CCO.
As the dollar's correspondent bank footprint keeps contracting in emerging markets, fintech-facing USD plumbing built on stablecoins is one of the structural sub-sectors drawing repeat institutional capital.
