Why Single-Layer Tools Fall Short

Every incumbent reads one axis well and the rest not at all: BuiltWith sees the stack, IPinfo sees the infra, Apollo sees the firmographics, and none of them see whether the domain ships AI. This cluster maps where each single-layer tool stops and why correlation across all five layers has to happen inside one crawl, not after five.

Frequently asked questions

Isn't a tech-stack detector like BuiltWith or Wappalyzer enough to profile a company?

No. Tech-stack detection is one layer, and it is the commoditized one. A framework and analytics list tells you what renders the page. It does not tell you who hosts it, whether SPF/DKIM/DMARC pass, whether the backend calls Anthropic or OpenAI, or whether the security headers grade a D. Profiling means reading infrastructure, firmographics, AI-readiness, and security against that stack, then correlating them. One axis read in isolation is a fingerprint, not a dossier.

Why not call five separate MCP servers and merge the results in my agent?

Because the merge is the expensive part, and fan-out cannot do it. Five servers hand you five payloads keyed differently, fetched at different moments, with no shared evidence trail. The signal you want lives in the correlation: does the detected AI SDK match the model provider seen on the wire, does the TLS cert issuer line up with the hosting org, does the llms.txt claim match the actual backend. That join happens inside one crawl or not at all. Coverage you can buy; fusion you cannot.

Sniff a domain.

Run sniff_domain on any site and read its five-layer dossier in one call.
