Former PCAOB Board Member Joins AI Audit Startup Oath

Christina Ho spent five years as a board member at the Public Company Accounting Oversight Board pushing the audit profession to adopt technology faster. When her term ended in January 2026, she didn't return to a Big 4 firm or academia. Instead, she joined Oath, a newly licensed U.S. audit startup building what it calls an "independent verification platform" for financial systems.

The move signals a fundamental rethinking of how audits are conducted. Oath aims to automate 80% of audit work by 2030, shifting from annual reviews to continuous, monthly verification.

Why it matters

When a former regulator bets her career on audit automation, it suggests the industry's structure is genuinely changing. The shift threatens the traditional talent pipeline—junior auditors typically perform the data extraction and document review work that automation targets. If 80% of audit tasks become automated, the profession's entry-level training model may need complete redesign.

From watchdog to startup

During her tenure at PCAOB from 2021 to January 2026, Ho repeatedly argued in speeches and public forums that audit remained too dependent on manual processes. According to The Wall Street Journal, which first reported the story, she pressed the profession to embrace available technology. When those efforts didn't produce the change she sought, she resigned and joined Oath.

The startup was founded by Lucas Ward, Christopher Pesigan, and Christophe F. It has already secured its CPA license and raised $6.6 million in seed funding in December 2025. To maintain audit independence, external funding supports only the non-audit side of the business, while CPAs strictly own auditing operations.

How continuous verification works

Oath's platform connects directly to client data sources—accounting systems, document repositories, and other financial infrastructure. The system automatically extracts and reconciles financial data, performing tasks like population testing, risk identification, and report generation on a continuous basis rather than once annually.

"Modern financial systems are built by machines. So why are humans still auditing them?" CEO Lucas Ward said.

The firm plans to start with private companies before expanding to public markets. Ward acknowledges that audit will never be fully automated—the final 20% involving professional judgment and signing audit opinions remains human work.

A wave of AI audit startups

Oath joins a growing field of venture-backed audit and accounting automation companies. Modus raised $85 million for AI audit infrastructure. Basis secured $100 million at a $1.15 billion valuation for AI accounting agents. Accrual launched with $75 million targeting preparation and review bottlenecks. Petual raised $20 million for internal audit and SOX workflow automation.

The trend is creating new roles, including what Oath calls "Accounting Engineers"—professionals who combine accounting knowledge with computer engineering expertise.

Geographic divide

The automation wave is concentrated in the United States, where a $50 billion audit market, high fees, and permissive VC funding rules create favorable economics. India's audit market faces different constraints: 96,000-plus CA firms competing, with the top 10 firms controlling just 39% of listed company audits, plus external funding restrictions that limit startup capital.
