Accountants and engineers, on the same ledger.
We built the software we always wanted to run books on — then we started running books on it.
The close got earlier. Then it disappeared.
DayZero is the point on the calendar where the close stops being an event. Getting there took four stages.
A firm that ships software.
We are not a software company that added services, or a firm that bought a tool. Every engagement runs on the platform — our accountants close books on the same product our engineers maintain, against the same ledger.
That loop is the whole model. Every fix an engagement needs — a missing reconciliation rule, a report a client asked for, an integration a close depended on — ships back into the platform, so the next engagement starts further ahead than the last one did.
Investment banking. Private equity. Engineering.
Our backgrounds span investment banking, private equity, and engineering. We know what institutional investors expect to see, because we've been the ones asking.
We're not hiring right now.
No open positions at the moment. If you want to talk about a pilot — or anything else — reach us at hello@ondayzero.com.

Schedule a pilot and talk to the accountants and engineers who wrote the software.
