Vaudit Launches TokenAudit to Recover Millions in Enterprise Token Spend Billing Errors From Anthropic, OpenAI, and AI Providers

Launches TokenAudit to Bring Independent Verification to AI Billing

SAN FRANCISCO--(BUSINESS WIRE)--Vaudit, the company building an independent verification layer across AI, cloud and enterprise billing, today launched TokenAudit to help companies audit AI bills against contract terms and recover money when billing errors occur. Since March, Vaudit has reviewed $34 million in AI spending across 60 companies and identified nearly $1.7 million in mistaken overcharges, with roughly 80% credited back by providers or cloud platforms, including AWS, Google Cloud, Microsoft Azure, Anthropic and OpenAI.

Worldwide AI spending is projected to reach $2.59 trillion in 2026, up 47% year over year, with AI infrastructure expected to account for more than 45% of total spend, according to Gartner. But as enterprises scale AI adoption across multiple model providers, model versions, and cloud platforms, billing is becoming harder to verify. Each vendor calculates usage inside its own system, leaving finance and engineering teams without a clear way to confirm whether invoices match what was actually used. The problem is becoming more urgent as “tokenmaxxing” moves from an engineering quirk to a business risk, with agent loops, retry storms, prompt bloat, routing issues, and failed requests quietly driving up costs.

“What we are observing is that enterprise AI billing has become increasingly opaque,” said Michael Hahn, founder and CEO of Vaudit. “Customers often don’t have independent visibility into which model actually handled a request, how it was routed, or whether it was cached, retried or deduplicated before it showed up on their bill.”

Vaudit customers install a software development kit inside their AI environment to capture raw usage data, reconcile it against invoices and flag discrepancies. The company has traced billing errors to five recurring patterns:

• Customers billed at premium rates for cheaper or older models
• Prompts that returned no output but were billed anyway
• “Retry storms,” in which autonomous agents repeat a failed request and rack up duplicate charges
• Billing that continued through provider outages
• Orchestration errors, in which a cloud provider sends the same request to two models at once.

Roughly half of the billing decisions Vaudit reviews run through cloud providers such as AWS Bedrock, Google Vertex, and Microsoft Azure rather than through model providers directly. Clear-cut billing errors are typically credited back within 48 to 96 hours.

"Enterprises are scaling AI faster than their finance teams can verify what they're being billed for, and that gap only widens as agents drive more usage,” said Omar Hamoui, partner at Mucker Capital. “We backed Vaudit because independent auditing of AI spend is becoming essential infrastructure, and TokenAudit puts real accountability behind a budget line growing faster than almost any other."

TokenAudit is the newest addition to a three-product platform that also includes Vaudit’s original ad-spend audit and an all-vendor audit layer covering cloud, SaaS and other categories. TokenAudit extends Vaudit’s existing approach into one of the fastest-growing enterprise spend categories: AI.

Hahn founded Vaudit in 2023 after building and scaling companies across AI, advertising technology and revenue operations, where he saw how quickly complex, vendor-reported costs can become difficult for enterprises to verify. TokenAudit applies that same focus on verification, usage data and accountability to enterprise AI billing. Current customers include: Panasonic, HP and Honda.
