Overt exists because we needed it and couldn't buy it.

None of them showed how they knew.
So we built our own: an engine that reads public infrastructure, keeps its own corpus fresh, and — the part that actually mattered — attaches the exact signal behind every detection. You stop trusting a list and start reading the evidence.
Overt is that engine, productized: a standalone platform for anyone who needs to know what a website runs — and to prove it.
Lists tell you what to believe.
Evidence lets you verify it.
— the difference between a guess and a fact
If we can't show the signal, we don't ship the claim. That rule built the product, and it writes this website too — every figure here traces to a query against the live database.
Detection reads what companies publish to the internet by operating there. No intrusion, no scraping behind logins, no scan-index purchases. The method survives legal review because there is nothing to hide in it.
We publish what the method cannot see, and the product says "none detected", never "none exists". A tool whose confidence you can trust is worth more than one that is always sure.
Depth in one market beats thin coverage of twenty. A market corpus is built the way a local rep would know it — official registries, financials, hiring, routing — and only then does the model move to the next market.
Publicly observable infrastructure signals about companies — response headers, DNS, certificates, routing announcements — and company records from public registries. Not individuals.
Contact and buying-team enrichment inside the product uses licensed data providers, under their lawful bases, with retention limits enforced in the platform.
