About Keelstone
Moving money should be as programmable as deploying code.
Keelstone exists because our founders were tired of running global finance through portals built two decades ago — fourteen logins, five spreadsheets, and a fax number for emergencies. We build the platform we wished existed: one ledger for payments, treasury, credit, and cards, with an API underneath everything and an audit trail behind every number.
The story so far
Seven years, one thesis
Pick a year to see what we shipped, broke, and learned along the way.
Keelstone is founded in Amsterdam
Maya Lindqvist and Tomás Ferreira start Keelstone with a simple thesis: moving money should be as programmable as deploying code. The first build is a multi-currency ledger and a payments API, run for three design partners out of a borrowed office above a bicycle shop.
How we work
Four values we actually use
They show up in code review and in pricing meetings, not just on the wall. Click any card for the unabridged version.
Leadership
The people signing off on it
Operators first — most of the leadership team ran finance, treasury, or payments infrastructure before building it.
We’re hiring across 5 teams.
Engineering, product, design, risk, and go-to-market — onsite in nine offices or remote across time zones. Come build infrastructure people trust with their payroll.
