Vaudit is a real-time AI audit engine that monitors advertising campaigns 24/7, detects billing anomalies, and generates legally defensible audit evidence to help businesses recover wasted ad spend. The platform reconciles reported ad spend with actual billing from vendors like Google and Meta and produces structured reports to flag irregularities, dispute charges, and pursue refunds. Since launching late last year, Vaudit supports 1,000+ customers worldwide, has audited more than 558 million advertising events, and is auditing over $150 million in annualized ad spend. The company reports in some cases recording up to 30% in monthly overcharges for customers when reconciling billed traffic. Vaudit, formerly BlokID, plans to accelerate development of agentic workflows to automatically optimize ad spend, refine its AI models to increase anomaly-detection precision, and expand coverage to mobile in-app traffic and platforms such as TikTok, X, and Amazon. The company also appointed Piotr Korzeniowski as COO to focus on product development and scaling operations. BlokID builds blockchain-powered privacy protection solutions aimed at the digital advertising ecosystem, providing an independent, immutable source of truth for ad verification and attribution. Its platform enables advertisers to verify ads, run attribution audits, and guarantee privacy with bonded privacy insurance through one-click campaigns. The company integrates with Google, Facebook, DV360, Xandr, and The Trade Desk to support advertisers and agencies. BlokID plans to roll out Google Analytics plug-ins and Financial Identity features to further empower users and safeguard information. Founded in July 2023 and led by CEO Michael Hahn, the company intends to use the seed funds to accelerate product development, focus on user acquisition, and begin market expansion. It targets a product launch by Q2 2024.
