Why Meridian

A real ledger under every primitive

Most stacks bolt accounting on at the end. Meridian starts with a correct, double-entry ledger and exposes cards, transfers, and payouts on top of it.

That means your balances reconcile in real time, and an audit is a query, not a project.

  • Double-entry by default
  • Programmable payouts
  • SOC 2 and PCI ready

One API

Cards, transfers, and payouts behind a single key.

Compliant

SOC 2 and PCI handled so you do not have to.

Instant payouts

Move money in forty currencies in seconds.

The ledger

Correct by construction

We start with a double-entry ledger and expose payments on top, so your balances reconcile in real time and an audit is a query.

The routing

Every cent takes the best path

Adaptive routing sends each transaction down the rail most likely to succeed, and retries the smart way when it does not.
