Apollo.io, founded in 2015, is a sales engagement and prospecting platform built around a database of more than 230 million contacts and 30 million companies, combined with outreach automation, lead routing, and CRM syncing in one system.
The platform positions itself as replacing several separate sales tools at once, a contact data provider, an outreach sequencer, a dialer, an enrichment service, and a lightweight CRM, built for sales and go-to-market teams doing outbound prospecting and pipeline management.
A free tier covers limited use, and paid plans start around $49 a month for more contacts and automation volume. For a sales team that wants contact data, outreach sequencing, and pipeline tracking unified in one platform rather than stitched together from separate point tools, Apollo.io's all-in-one approach addresses that directly.
