Vaudit, the world’s first AI-driven Refund Engine for digital advertising, today announced that in 2025 it has officially audited more than $1 billion in annualized ad spend and processed over $100 million in refunds for global brands.

This milestone reinforces Vaudit’s role as the most trusted partner for marketing, growth and finance teams seeking verifiable transparency and automated recovery from invalid traffic, billing errors, and platform overcharges across Google, Meta, AppLovin, Amazon Ads and other major publishers.

Trusted by global leaders including Accenture, HP, Panasonic, Volkswagen, and thousands of mid-market and enterprise advertisers, Vaudit is also one of just 30 companies worldwide approved as a Google Certified Click Auditor which validates the accuracy, security, and integrity of its click-level audit methodology.

Vaudit’s growth has accelerated dramatically through 2025, powered by the increasing volume of refunds automated by its platform and rapid adoption among enterprise and mid-market brands. Earlier this year, Vaudit raised $7.3 million in seed funding led by Mucker Capital; with participation from AVV, AppWorks, and notable adtech angels including founders of AdMob and Klout, bringing total funding to $8.5 million. This investment has directly fueled the scaling of Vaudit’s refund automation engine, expansion into new publisher ecosystems, and increased capacity to process tens of millions in monthly refund requests.

“Vaudit was built on a simple but radical promise: every advertising dollar should be verifiable, valid, and valuable,” said Michael Hahn, Founder and CEO of Vaudit. “Crossing $1 billion audited in 2025 and returning over $100 million to brands like Accenture, HP, Panasonic, and Volkswagen is proof that the industry is done accepting waste. Our success-fee model removes all risk for the advertiser and our automation removes the waste from the invoice before it ever gets paid.”

Vaudit’s proprietary Consensus Engine™ identifies only the invalid traffic and billing discrepancies that the platforms themselves, as well as MRC, IAB, and TAG standards, agree are fraudulent. This approach delivers industry-leading recovery rates of 8–15%, with all refunds and removals processed on a pure success-fee basis, eliminating any financial risk for advertisers and accelerating adoption.
