Accounting is 5,000years old. It has beenautomated for about40 of them.
We build the environments that finish the job.
The oldest information system on earth. Every time it changed.
The median company still waits this long after the month ends to find out what happened in it.
Then the year ends and the audit starts. Two and a half person-years of it, on one engagement, one company.
Listed companies, KOSPI main board, averaged 2024. The only market that publishes the figure.The oldest information system on earth. Every time it changed.
Writing is invented to keep accounts.85% of the earliest known tablets are inventories.
The textbook is printed in Venice.Pacioli invented nothing. He wrote down what merchants already did.
England stops keeping its national accounts on notched sticks.Eight years later the leftovers burn, and take the Palace of Westminster with them.
Excel ships, on a Macintosh.The last time the tooling fundamentally changed.

4,734 hours.Auditor time on a single annual engagement. Two and a half person-years. Listed companies, KOSPI main board, averaged 2024. The only market that publishes the figure.
The largest verification workload on earth, done by hand.
The regulator found a deficiency in 46% of the audits it inspected.
We build worlds, not datasets.
A dataset says what someone once did. An environment makes the model do the work, in a real ledger, against a real answer.
Ledgers that run a year. Subledgers that have to tie. And somewhere inside, the error a good accountant finds on the third pass.
Real state, real order
Month six inherits month five.
Deterministic verifiers
Six invariants. Arithmetic decides, not a panel.
Authored answer keys
Never in a pretraining corpus. Never will be.
Built by people who did the work.
