Tomas Lindqvist
Co-founder & CTO
Wrote the first double-entry core over a winter; still reviews every schema migration.
01 — Why Ledger exists
Ledger was founded by payments engineers who spent a decade reconciling other people's money by hand. We built the settlement core we always needed — double-entry at the bottom, one API on top.
02 — Operating principles
The product ambition is an infrastructure layer nobody thinks about — because it has never once disagreed with the bank statement.
03 — From API call to closed books
Three calls. Zero drift.
A sandbox key to a production payout in a sprint — the reconciliation comes built in, not bolted on.
Create accounts and balances with one POST. Sandbox mirrors production rail-for-rail.
Trigger payouts over the fastest local rail. Webhooks confirm every state change in real time.
Every movement posts twice to the ledger core. Export audit-ready statements any hour of any day.
04 — The road to 41 markets
Five years, one core, zero drift.
Founded in Amsterdam
Two payments engineers ship the first double-entry core to production with a pair of design-partner platforms.
/2021
Payouts GA
Local rails live in 12 markets; the Series A funds the treasury roadmap.
/2022
Treasury launch
Multi-currency balances with real-time FX quoting join the same reconciled core.

05 — The people on pager duty
Payments engineers, first and last.
Everyone who ships code at Ledger has carried the settlement pager. It keeps the roadmap honest.
