Common questions.

Is AgentEnrich a BuiltWith alternative?

For light-to-medium tech-stack use, yes. BuiltWith's edge is depth of detection + historical data. AgentEnrich is broader (tech + people + signals + SMB) at lower price.

Can I do BuiltWith-style 'find all sites using X' searches?

Yes via POST /v1/tech-stack-targets. Returns companies using a specific tech + the relevant decision maker at each. Combines tech-detection with identity layer.

Does AgentEnrich have BuiltWith's historical tech-trends?

No. We surface current tech state, not multi-year historical timelines. If you need 'show me how a company's tech stack evolved 2018-2024,' BuiltWith is the right pick.

Is AgentEnrich cheaper?

Yes. BuiltWith Pro is $495/mo. AgentEnrich Pro is $97/mo with 31 endpoints + signals + SMB + MCP.

3 data layers. One API key.
7-day free trial, no card.
