Modern Treasury Launches Unified Payments API

Modern Treasury, co-founded by Dimitri Dadiomov, Matt Marcus, and Sam Aarons in 2018, is now valued at over $2 billion after raising a total of $183 million in funding. The company's core mission is to automate and streamline payment operations, a pain point Dadiomov experienced firsthand while working at online mortgage lender LendingHome. The new "Payments" API is built on the same infrastructure that has already processed over $400 billion for clients like Gusto, Navan, and Procore. The platform's key innovation is unifying disparate payment rails—from traditional ACH and wires to real-time systems like RTP and FedNow, and blockchain-based stablecoins—into a single point of integration. This approach is designed to slash the typical 6-to-12 month bank onboarding and integration timeline, allowing developers to launch payment functionalities in days. By handling compliance checks like KYC/KYB and providing a unified ledger for real-time reconciliation, the API aims to reduce the significant engineering overhead and vendor fragmentation developers typically face. The inclusion of stablecoins like USDC, USDP, and USDG (with USDT planned) positions the platform for developers building at the intersection of traditional finance and digital assets. This allows for seamless on and off-ramps between fiat and crypto, enabling use cases like instant global payouts to creators and gig workers, which are often faster and cheaper than legacy international wire transfers. Modern Treasury has bolstered this capability through partnerships with Paxos and Circle, and the earlier acquisition of Beam. This unified model directly addresses the high costs and complexity of building payment systems from scratch, which can range from $200,000 to over $1 million for initial development, plus ongoing compliance and infrastructure expenses. The platform operates on a usage-based pricing model, eliminating the need for long-term volume commitments and appealing to startups and teams scaling their products. This structure allows a company to start with Modern Treasury's PSP and later add direct bank relationships without needing to re-do the initial integration.
