What is Leadinfo

Leadinfo tracks anonymous B2B website traffic and matches it to company records, surfacing firmographic details, page-level behavior, and contact information for decision-makers in real time. It's built for SDR/BDR teams, marketers, and RevOps at SMBs and mid-market companies that want to act on inbound interest before it goes cold. The standout capability is AI and bot-filtered buying intent signals — rather than dumping every session into a queue, Leadinfo filters out noise so reps see companies that are actually showing purchase behavior. It connects natively to HubSpot, Salesforce, Pipedrive, and Slack, and routes through Zapier or Make for everything else. The honest limitation: coverage is strongest in European markets, and teams with primarily North American traffic may find identification rates thinner than expected.

Our verdict

Vanderbuild take

Leadinfo is a focused visitor identification and intent signal tool — a solid fit for SDR/BDR and marketing teams at growth-stage companies that want to convert inbound website traffic into named pipeline without waiting for a form fill. The API exists, but agentic readiness is limited — you can pull data programmatically, but expect to hit friction before you've built anything resembling an autonomous outbound loop on top of it; MCP status is unconfirmed. Pricing starts at €49/month and scales by companies identified, which is affordable for small teams testing the motion, though costs climb noticeably once you're identifying 500+ companies per month. The biggest watch-out is geographic: identification rates skew toward European traffic, so North American-heavy pipelines may see lower match rates than the headline numbers suggest.
