The company supports 1,000+ customers worldwide and has audited more than 558 million advertising events. Since launching late last year, Vaudit is now auditing over $150 million in annualized ad spend, and in some cases recording up to 30% in monthly overcharges for customers when reconciling against the traffic they were actually billed for. Vaudit services channel partners who are looking to enhance their value proposition for clients regularly running ad campaigns, as well as leading consumer and enterprise brands such as Accenture, HP, Huawei, Husqvarna, Marmot, Panasonic, RE/MAX, SAP and Volkswagen. ‍

“We’re excited to partner with adtech veterans like Omar and Binh to pioneer a new standard in digital advertising accountability,” said Michael Hahn, Founder and CEO of Vaudit. “The online advertising industry has normalized waste and fraud for far too long, with clicks that don’t track, campaigns that overspend, and billing that goes unverified.”
