Tested Web

Tested Web is an on-chain data verification project started in Austin in 2021, later renamed Polygraf AI. Its business is flagging statements that do not match public chain records and offline evidence: it uses crawling and cross-verification to check claims about the links between wallets, projects and people, producing verification reports for due diligence and risk teams.

It targets the industry's flood of unverifiable claims by breaking assertions into individually checkable on-chain facts so results can be reproduced. In the first half of 2026 its verification method received a US patent grant, and it launched Meeting Guard, a product for online conferences that checks the consistency of identity and content during events. The platform emphasizes reproducible cross-checking, with structured report output that plugs into due diligence and risk workflows.
