Tesser is a New York-based stablecoin payments infrastructure company that lets licensed financial institutions, banks, fintechs, and payment service providers move money across borders instantly and compliantly on modern stablecoin rails.

The Tesser API (OpenAPI 3.1, v1) exposes accounts, counterparties, tenants, payments, and treasury operations (deposits, withdrawals, rebalances) secured with Auth0 client-credentials JWTs, plus Ed25519-signed webhooks, first-party TypeScript and Kotlin signer SDKs, a published Model Context Protocol server, and an open-source agentic onboarding skill. Founded by Geetha Panchapakesan (ex-MoneyGram, Visa Direct, Circle); raised a $4.5M seed in October 2025 led by Castle Island Ventures with Anthemis, Strobe Ventures, and Digital Currency Group.
