About Apollo.io

Apollo.io is a sales intelligence and engagement platform that provides access to a massive B2B database of over 270 million contacts and 60 million companies.

About Clay

Clay is a data enrichment and outreach automation platform that aggregates data from over 75 providers using a 'waterfall' approach — sequentially querying multiple sources to maximize coverage and accuracy for any given lead. It's designed for sales, growth, and RevOps teams who need to build targeted prospect lists, enrich contact data, and craft personalized outbound messaging at scale. What makes Clay unique is its spreadsheet-like interface combined with AI-powered agents that can research companies, clean messy data, and write tailored emails based on enriched information. It essentially replaces a patchwork of individual data tools and manual research workflows with a single, programmable workspace.
