Overview
What Apollo.io does
Apollo.io is a go-to-market platform built for B2B sales and marketing teams. It pairs a large contact and company database with prospecting tools, data enrichment, and outbound engagement features so reps can identify prospects and reach them without switching between separate tools.
Data and prospecting
The platform offers advanced search filters across millions of contacts and accounts, letting users build targeted lead lists by attributes such as title, industry, company size, and technology used. Verified email and phone data can be enriched into existing records, and signals help prioritize which accounts to pursue.
Outreach and automation
Apollo.io supports multi-channel sequences spanning email, calls, and LinkedIn tasks, with A/B testing and analytics to track engagement. AI-assisted writing and workflow features help draft messages and automate follow-ups, and the platform integrates with common CRMs to keep data in sync.
Who it is for
Apollo.io is widely adopted by sales development, account executive, and revenue teams at startups and mid-market companies, though plans scale to larger organizations. It is often chosen as a combined alternative to running a separate database, sequencer, and enrichment tool.
