BlokID

BlokID is an AI-native ad spend auditing platform, now operating under the brand name Vaudit, that helps businesses detect billing violations, recover overcharges, and protect ad budgets from waste across advertising, AI, and SaaS vendors. The platform deploys a fleet of specialized AI agents that continuously audit vendor invoices, reconcile charges against contracted terms and actual usage data, flag anomalies, and file recovery claims — recovering money 24/7 without requiring manual audit teams. BlokID/Vaudit serves advertisers running campaigns on platforms such as Google Ads, Meta Ads, TikTok, and Trade Desk, as well as companies with AI infrastructure spend across providers like OpenAI, Anthropic, and AWS. The company raised a $7.3M seed round in 2025 and has audited over $1 billion in spend, recovering more than $50 million for clients.
