About Apollo.io
Apollo compressed the sales stack: a database of roughly 275 million contacts, plus email sequencing, dialing, and intent signals, at prices that undercut buying ZoomInfo and Outreach separately. Data quality varies by region and the free tier keeps tightening, but for outbound teams building pipeline from scratch it has become the default first purchase.
