nts. It's the same engine behind the CallPrep Chrome extension, exposed as an API, a drop-in Clearbit / Apollo alternative built for agents, not dashboards.

What makes it different is where the research lands:

- HubSpot / Salesforce / Pipedrive / Attio - new contacts auto-fill with decision-makers and pain points, so your SDR opens an already-done card.

- Outbound email - every send opens with a real prospect-specific line instead of a generic merge tag.

- Your LLM agent (Claude, etc.) - answers "who should I email at Acme today" with a real list, not a guess.

Native HubSpot, Slack, and Claude integrations turn what used to be an hour of n8n wiring into a 5-minute native call. Start free in the Sandbox, enrich a real prospect and ship the same day.

Built for: founders and devs shipping AI SDRs, sales agents, and GTM automations who are tired of paying Clearbit's high floor or getting sparse Apollo coverage.

You're building an AI SDR, an n8n flow, or an in-house sales agent, and it keeps hitting the same wall: it can draft a great email, but it doesn't actually know who the prospect is. So it hallucinates the company, the role, the pain point.

CallPrep's API is the prospect-research layer that fixes that. Give it an email (or a name + company), get back a sales-ready battlecard: company overview, decision-makers, likely pain points by stage, opening plays, and talking points.
