About Apollo.io
Apollo.io is a sales intelligence and engagement platform from San Francisco that combines a B2B database of more than 270 million contacts and tens of millions of companies with the tools to reach them. Many startups use it as their prospecting data source, outbound tool and, at first, a lightweight CRM, all in one subscription.
Prospecting starts with filters for title, seniority, industry, headcount, technologies, funding and buying intent, and a Chrome extension surfaces emails and phone numbers on LinkedIn and company websites. Contacts flow into sequences that mix automated emails, call tasks and LinkedIn steps, with a built-in dialer, call recording, meeting scheduler, enrichment of existing CRM records and AI that researches accounts and drafts personalized messages. Usage runs on credits for emails, mobile numbers and exports. The free plan is unusually generous for a data vendor, and paid plans are priced per user per month, rising through Basic and Professional tiers to a Custom plan for larger teams.
Apollo fits startups, SMB sales teams and founders doing outbound who need data and sequencing at a fraction of ZoomInfo's price. Email accuracy is generally good, mobile numbers are weaker, and teams must manage sending limits and domain health to protect deliverability. ZoomInfo offers deeper enterprise data, Clay is better for multi-source enrichment and research workflows, and Instantly or lemlist focus on outreach volume and personalization. Coverage of Turkish companies exists but is thinner than for the US and Western Europe.
