Rutter

Rutter is the unified API infrastructure powering the next generation of B2B fintech. We help tech-forward companies build seamlessly integrated financial products by connecting to their customers' systems of record, from accounting platforms to e-commerce systems.

The financial operations landscape is fragmented across hundreds of platforms (QuickBooks, NetSuite, Shopify, Stripe, etc.). Without Rutter, companies must spend thousands of engineering hours building and maintaining these critical integrations.

Our Universal API provides the same level of granularity as direct integrations while using a single, consistent schema. This enables our customers to build end-to-end workflows for financial planning, lending, expense management, AP/AR automation, and more, in days, not months.

Leading fintechs like Mercury, Airwallex, and Orb trust Rutter to power their integrated financial solutions.

Origin Story

Rutter was founded in 2021 by Eric Yu and Peter Zhou, emerging from Y Combinator’s Summer 2019 batch[1]. The founders brought technical expertise and a vision to unify fragmented financial data systems into a single API, inspired by the success of Plaid in banking data but targeting commerce, payments, and accounting data instead[4]. Early traction came from fintech companies seeking to automate financial workflows without the burden of maintaining multiple complex integrations, positioning Rutter as a critical infrastructure layer in B2B fintech[1][4].
