Apollo.io

Sales platform with a 240-million-contact database and e-mail sequencing

Overview

Apollo.io was founded in 2015 by Tim Zheng, its chief executive, and Ray Li, its chief technology officer. Its investors include Bain, Sequoia, Tribe, Nexus, NewView and Y Combinator. The company says it has 40,000 paying customers and that 1 million sales professionals use it to enrich and analyse prospect data.[9]

The product combines a database of 240 million contacts and 30 million companies with sales-engagement features normally sold separately: email sequencing, a dialler with call recording on higher plans, CRM integrations and AI features.[8][9] This combination makes it the main published-price alternative to ZoomInfo for small and mid-sized teams.

Apollo.io offers a free plan that it says stays free with no time limit; free accounts can connect Gmail mailboxes only. The Basic plan targets individual sellers doing regular outbound, Professional adds higher credit limits, AI features, call recording and advanced CRM integrations, and Custom covers SSO, advanced security, custom volumes and API access.[8] Credits are pooled across a team, granted at the start of each billing cycle and expire at the end of it without rolling over; extra credits can be bought and renew each cycle until removed. Without a higher-tier limit, users can export up to 10,000 leads in one action.[8] Limitations include the expiring credits, API access restricted to Custom plans, and phone coverage that buyers in Europe often supplement with a specialist provider.
