What we do not pretend to be
A comparison is only useful if it also lists what the other tools do better. Here is where they win.
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 and 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 do not. If outbound calling is your primary motion, Apollo is the right tool.
We are not charging you for AI
Instantly bundles AI credits. We ask you to bring your own key — Anthropic, any OpenAI-compatible provider, or self-hosted Ollama or vLLM. No lock-in on inference cost.
