a16z Backs Petual, the AI Startup Automating Enterprise Audit Compliance
Andreessen Horowitz (a16z) has announced its investment in Petual, an AI audit compliance platform built to transform how large enterprises handle internal audit and regulatory testing. The announcement, made on April 23, 2026, marks another bold bet by the storied venture firm on AI solving deeply entrenched enterprise pain points.
Internal audit is one of the most universally painful functions in corporate America. Every public company must conduct audits at scale, with zero room for error and personal liability for executives who sign off. Across the U.S., roughly 15,000 companies employ approximately 250,000 audit professionals, collectively spending over $30 billion annually on the function.
Why SOX Is the Breaking Point
A significant chunk of that spend, around $8 billion per year, goes toward Sarbanes-Oxley (SOX) compliance alone. Audit teams spend nearly 60 percent of their time on SOX requirements, and two-thirds of that time consumed by testing. The work is entirely manual, with auditors sifting through unstructured files, cross-referencing evidence, and logging findings into spreadsheets and Word documents.
Petual’s AI audit compliance platform changes that equation. By automating the repetitive, document-heavy testing process, it frees audit teams to focus on strategic risk identification and governance the work that actually requires human judgment. According to a16z’s announcement, one enterprise customer described Petual as “utterly transformative,” while another reported cutting their audit budget to a quarter of its previous size.
The platform is already working with over a dozen large public companies, including multiple Fortune 500 and NASDAQ 100 firms a rare achievement for an early-stage startup.
Petual was founded by Snir, a second-time founder who previously led engineering at Retool and held senior roles at Lyft. His team includes Lyft’s former Chief Audit Officer.
