Modern Treasury

Modern Treasury is a San Francisco payment operations and ledger company founded in 2018 by Dimitri Dadiomov, Matt Marcus and Sam Aarons. It targets the accounting and reconciliation layer that breaks when a software company or an embedded finance programme moves money at scale: payment initiation, approvals, bank file handling, and matching bank activity back to internal balances.

The platform offers one API across multiple payment rails including ACH, wire, RTP, FedNow and stablecoins, together with programmable accounts, real-time reporting and built-in compliance. Its Ledgers product is a double-entry transaction database built for immutability and auditability, supporting account hierarchies up to five levels deep, millions of accounts with live balance aggregation, reconciliation against bank balances and automated warehouse sync. Typical uses are digital wallets, card programmes, sub-account structures, lending, payroll and rewards. Named customers include Robinhood, Gusto, Procore, Navan, GoFundMe, AvidXchange and Anchorage Digital. The company reports more than $600 billion in payments processed.
