Our agents test whether a company's financial, operational, and technology controls actually work, and trace every conclusion to its source.\n\nThe hard part isn't speed. It's being right. External auditors re-perform our work, so precision on sample 1 has to equal precision on sample 400, and an agent that can't support a conclusion has to say so rather than guess. We're backed by Andreessen Horowitz; the team comes from Stripe, Retool, and Lyft; and public companies already run their SOX programs on Petual.\n\nThe Opportunity\n\nThe interesting problem is not getting an agent to test a control once. It is knowing whether it was right across hundreds of controls, for customers whose methodologies all differ, where the ground truth is a senior auditor's judgment rather than a label in a dataset.
