Why we publish this

What we don't pretend to be

We are NOT a 230M-contact database

Apollo has 230M verified contacts; ours is a curated 17M-contact import pool aggregated from public B2B sources and de-duplicated. Smaller — but included at no extra cost, live in the app today. Need more? Bulk-import your own lists via the API.

We are NOT a phone dialer (yet)

Apollo ships a native cold-call dialer. We don't. If outbound calling is your primary motion, Apollo is the right tool.

We are NOT charging you for AI

Instantly bundles AI credits. We make you bring your own key (Anthropic, OpenAI-compatible, self-hosted Ollama/vLLM — your call). No vendor lock-in on inference cost.

Bring your data. Bring your LLM. Send today.

One pipeline on mailboxes you own, with AI on your own key. Free tier at launch — no card, no sales call.
