About

What is Coldlytics

Coldlytics builds B2B prospect lists on demand by layering automation and AI with manual human research — scraping Google Maps and LinkedIn, then verifying every contact through ZeroBounce before delivery. It's built for SDRs, BDRs, marketing teams, and agencies at SMBs and mid-market companies that need targeted lists without maintaining their own data infrastructure. The standout capability is website keyword targeting: you can filter prospects by terms found on their own sites, which opens up niche segments — including small businesses and blue-collar industries — that most databases ignore entirely. Lists are delivered within 24 hours, with native connections to HubSpot, Salesforce, and Zapier for handoff. That said, Coldlytics is a list-building service, not a sequencing or outreach tool — once the data lands, execution is entirely on you.

Our verdict

Vanderbuild take

Coldlytics sits in a specific lane of the prospecting database and data enrichment space: it's a research-as-a-service model that trades self-serve speed for higher data accuracy, and we think that trade-off makes sense for agencies and SDR teams targeting niches that Apollo or ZoomInfo simply don't cover well. On the agentic readiness front, the API exists and webhooks are supported, but this is a Limited setup — you can pull lists programmatically, but there's no MCP server and the API isn't built for the kind of real-time, high-frequency calls that a fully agentic outbound workflow would demand. Pricing isn't publicly confirmed, so budget conversations will need to happen directly with their team before you commit. The honest ceiling here is scope: Coldlytics hands you a list and stops — there's no sequencing, no intent signals, and no enrichment waterfall, so you'll need your own outreach stack sitting downstream.

Where this tool slots into an agentic pipeline.

Plays the role of Data source + Enricher + Verifier in an agentic pipeline. Use it to source contacts, companies, and the raw inputs an agent needs to act; add firmographic, technographic, and signal data to a lead row on the fly.
