Apollo.io

What Apollo.io does

Apollo.io is an AI-native go-to-market operating system, founded in 2015 and headquartered in San Francisco, that consolidates B2B data, outbound sequencing, inbound lead routing, enrichment, a parallel dialer, conversation intelligence, and deal execution into a single platform. Its core technology is built on a living data network of 230M+ contacts and 30M+ companies, refreshed through a 2M+ contributor network with a 7-step verification process that delivers 97% email accuracy. AI capabilities are embedded across the workflow rather than offered as a separate layer: an AI Assistant executes multi-step GTM tasks autonomously, a Model Context Protocol (MCP) server connects Apollo natively to Claude, ChatGPT, and Perplexity, and AI-powered call recording/transcription with CRM auto-update drives the deal-execution module.

Apollo operates a tiered SaaS model ranging from a free 900-credit tier up through $49-$119/seat/month paid plans and custom enterprise contracts, with bundled pricing replacing an earlier credit-only structure. The go-to-market combines product-led growth (self-serve free signup, Chrome extension, G2-driven acquisition) with a growing enterprise field-sales motion, and a developer/API channel through docs.apollo.io and the Orthogonal API marketplace. The platform serves more than 600,000 companies and 2M users globally, spanning SMB and mid-market buyers as the historical core plus an enterprise segment that grew 400%+ over the trailing 12 months as of March 2026.

The business has raised approximately $251M across six disclosed rounds, with the most recent being a $100M Series D led by Bain Capital Ventures in 2023 at a $1.6B post-money valuation. ARR is approaching $200M (with $145M reported in May 2025), implying roughly 5x revenue growth since the Series D, and management has publicly targeted $500M+ ARR. Apollo completed its first acquisition (Pocus, March 2026), added a CFO, CRO, CMO, and CPO during 2025-2026, and transitioned Matt Curl from COO to CEO while co-founder Tim Zheng moved to Chairman — a leadership configuration consistent with a company preparing for the next stage of scale.
