Petual Raises $20M to Automate SOX Compliance With Agentic AI Platform

Petual has raised $20 million to automate one of corporate America’s most expensive regulatory burdens: Sarbanes-Oxley compliance. The San Francisco-based startup closed a $17 million round led by Andreessen Horowitz alongside a $3.2 million earlier round led by First Round Capital. Cowboy Ventures, prominent angel investor Elad Gil, and the founders of Lyft and Opendoor also participated. Petual will use the capital to accelerate product development and scale go-to-market operations in a compliance market that consumes more than $8 billion annually in the United States alone.

The company is attacking Sarbanes-Oxley compliance, the post-Enron regulatory framework that has governed financial reporting at every publicly traded company in America since 2002. SOX mandates rigorous internal controls testing, and for the roughly 15,000 companies that maintain internal audit teams, employing some 250,000 professionals at a collective annual cost exceeding $30 billion, the process remains stubbornly manual. Auditors spend the bulk of their time wading through hundreds of unstructured files per control test: PDFs, spreadsheets, screenshots, email threads. They collect evidence, cross-reference it against test procedures, and produce documentation for external auditors. Internal audit teams dedicate approximately 60% of their hours to SOX requirements, and roughly two-thirds of that time goes to testing alone. It is precisely the kind of repetitive, document-heavy workflow where agentic AI can deliver outsized returns, and where Petual has chosen to plant its flag.

Founded by Snir Kodesh, a two-time entrepreneur and Stanford computer science graduate, Petual brings an unusual combination of deep engineering talent and genuine audit-industry expertise to a problem long dominated by legacy GRC software vendors. Kodesh previously led engineering at Retool and before that co-founded Hitch, a ride-sharing venture acquired by Lyft. That track record caught the attention of a16z general partner Brian Roberts, who now sits on Petual’s board. Roberts is himself a former chief financial officer at both Lyft and Splunk. He understands the compliance burden from the inside, and has noted publicly that it is rare to see an early-stage company penetrate large enterprise accounts as quickly as Petual has managed.

The leadership bench around Kodesh reinforces the thesis that domain expertise matters in compliance technology. Eliot Walker, formerly the chief technology officer of Lyft’s Fleet division, brings more than a decade of experience in applied machine learning and large-scale distributed systems built at Lyft and Amazon. David Coulombe, Lyft’s former vice president of internal audit and chief audit executive, rounds out the founding team with decades of experience managing SOX programmes and enterprise risk at public companies. The inclusion of an actual audit leader alongside engineers and machine learning specialists is a deliberate choice. It shapes everything from how Petual’s AI agents reason through evidence to how the platform formats its outputs for external auditors.

What Petual has built is a platform powered by agentic AI, meaning autonomous agents capable of executing multi-step workflows with minimal human intervention. The agents gather evidence, map it to controls and samples, perform tests against established procedures, and generate complete, auditor-ready work papers. The system ingests both structured and unstructured data: spreadsheets, ERP exports, scanned PDFs, screenshots of system configurations. Where a human auditor might spend anywhere from several hours to well over a hundred hours producing documentation for a single control, Petual’s agents deliver comparable output in minutes. Critically, the platform preserves a built-in review and approval workflow so that human oversight remains central to the process. Every conclusion is traceable back to its source material, and outputs are formatted to satisfy the templates of the Big Four accounting firms and other external auditors.

Early traction suggests Petual has found genuine product-market fit in a category where enterprise buyers are notoriously cautious. The company already counts more than a dozen large public companies among its customers, including members of both the S&P 500 and the NASDAQ 100 across industries spanning energy, software, infrastructure, manufacturing and financial services. Those clients report efficiency gains of 68 to 80% on existing SOX workflows, a staggering figure in a function where even incremental improvements tend to be hard-won. Erin Dempsey Heuwetter, the head of audit, risk and compliance at travel management platform Navan, has said the platform allows her team to maintain audit quality while operating at a fraction of the time cost. Sumeet Puri, the chief accounting officer at Eos Energy Enterprises, has described Petual as a tool that strengthens audit execution while freeing his team to concentrate on risk analysis and oversight rather than mechanical documentation. One customer, according to a16z’s investment memo, went so far as to say Petual had allowed them to reduce their compliance budget to a quarter of its previous level.

The timing of Petual’s raise reflects a broader convergence of forces. The global enterprise governance, risk and compliance market was valued at approximately $49.5 billion in 2026 and is projected to approach $115 billion by 2035, growing at nearly 10% annually. Within that market, SOX compliance software alone reached $1.32 billion in 2024 and is expanding at roughly 12% per year. At the same time, corporate audit teams are under mounting pressure to deliver more with less. Average ongoing SOX compliance costs run approximately $2.9 million per year for large companies, and first-year implementation costs can be two to three times that figure. Automation has long been identified as the most direct path to lowering those costs, yet the majority of audit teams remain in the early stages of adoption. A recent Petual survey found that roughly 72% of audit teams operate at below 30% automation in their SOX testing processes, suggesting enormous headroom for a product that can demonstrably compress the work.

For Andreessen Horowitz, the investment represents a bet not just on SOX but on the broader potential of agentic AI to restructure entire enterprise functions. The firm’s investment thesis, articulated in a public memo by Roberts, frames SOX testing as a beachhead. The longer-term vision is for Petual to transform every audit and compliance team into what Roberts describes as a proactive, AI-powered control system for the enterprise. If the company can prove that autonomous agents can reliably handle the most document-intensive, liability-laden workflows in corporate finance, where the CEO and CFO personally attest to accuracy and face criminal penalties for fraud, then the same architecture could extend to broader internal audit, operational compliance, and enterprise risk management.

Petual is not operating in a vacuum. The compliance technology landscape includes established vendors such as AuditBoard, Workiva and SAP’s GRC suite, as well as a growing cohort of AI-native startups targeting adjacent audit and risk workflows. But the company’s early enterprise traction, its blend of engineering and audit domain expertise, and the depth of its investor syndicate position it favourably in what remains a fragmented and underautomated market. The $20 million raise gives Petual the runway to deepen its product, expand its sales team, and push into new compliance domains beyond SOX. With the broader internal audit market consuming $30 billion a year and SOX accounting for roughly a quarter of that spend, the beachhead is already large. The territory beyond it is larger still.
