Andera is an AI platform that automates internal audit and controls testing, targeting the Excel-heavy workflows that finance and audit teams at public companies use to satisfy Sarbanes-Oxley, operational, and compliance requirements. Instead of humans manually collecting evidence, sampling populations, and drafting workpapers, Andera runs agents that read across thousands of pages of source documents, reason about whether the evidence satisfies a control objective, and produce documentation in the same format auditors already use. The company is built by co-founders Aryo Patel (CEO) and Tinah Hong (CTO), and its platform is engineered to automate manual, Excel-heavy Sarbanes-Oxley (SOX), operational, and compliance testing workflows. The launch matters because internal audit is one of the largest reasoning-heavy back-office functions that has resisted automation, and the economics are painful. For the average public company, audit fees cost $3M annually, and Fortune 100 companies spend north of $20M annually. Andera's bet is that audit is fundamentally a reasoning problem rather than a rules problem, requiring an auditor to read complex, multi-format evidence, reason about whether it satisfies a control objective, and produce documentation that holds up to regulatory scrutiny. The convergence of large language model reasoning, long context windows, and agentic tool use has changed what is now possible. The launch video frames this through Enron, arguing that fraud is cheap to hide across millions of spreadsheets and expensive to find without agents that can hold formatting choices from page 4,000 in mind while reading page 40,000. Andera is a San Francisco company that has raised a $37M Series A led by Lightspeed Venture Partners to automate internal audit from end to end. Patel previously worked on Azure infrastructure scaling at Microsoft and on the trading desk at Jane Street , and Hong was previously at Stripe and Microsoft. The pitch to finance leaders, Big Four practitioners, and CFOs is straightforward: keep the workpaper format your auditors already accept, and let agents do the sampling, tie-outs, and evidence review that currently consumes the bulk of a controls tester's week.
