Apollo.io is the company behind the industry’s first fully agentic GTM platform, transforming how revenue teams execute. Going beyond automation, Apollo’s intelligent agents actively drive results across the entire sales funnel – from prospecting to deal management – all in one place. Trusted by millions of users and hundreds of thousands of companies – including Anthropic, Autodesk, and Docusign – Apollo is making world-class go-to-market simple, intelligent, and accessible for all. Apollo serves sales development representatives, account executives, sales leaders, revenue operations, and marketing teams at B2B organizations of various sizes. Teams use Apollo to build and maintain target account lists, orchestrate outbound and inbound motions, manage opportunities, and understand which activities lead to qualified pipeline and closed revenue. Key capabilities include: Data and targeting: Access to a large B2B database with company and contact details, including firmographic, technographic, and buyer signal data, so users can define ideal customer profiles and create precise segments for outreach. Prospecting and enrichment: Tools to search, filter, and save prospect lists, plus enrichment workflows that keep contact and account records up to date in Apollo and connected systems such as CRM. Sales engagement: Multi-step, multi-channel sequences for email, calls, and tasks that standardize how reps follow up with prospects, with controls for timing, throttling, and deliverability. Agentic and AI-assisted workflows: Intelligent agents and AI features that help with account research, lead scoring, message generation, and next-step recommendations so reps can prioritize and personalize at scale. Deal and activity management: Basic CRM-style functionality for tracking opportunities, stages, activities, and notes, giving teams a single view of pipeline health and sales performance. By combining data, engagement, and deal execution in one platform, Apollo is designed to reduce the number of disconnected tools in a typical GTM stack and provide a consistent workflow for building pipeline and managing deals.
