What Is Double?

Claim this Tool

Double is an AI-driven lead research and enrichment platform designed to replace manual prospect Googling. Sales and marketing teams can ask natural-language questions—such as whether a company is remote-first, SOC II compliant, B2B, or runs a call center—and receive structured, sourced answers at scale.

The tool can research thousands of prospects at once, identify key attributes that impact targeting and qualification, and help users find specific segments like remote-first companies. Double also aggregates over 10 private data sources to provide verified email addresses, positioning itself as a more comprehensive alternative to tools like Apollo and RocketReach.

By centralizing research, qualification, and email verification, Double streamlines outbound workflows and helps teams build more accurate, higher-converting campaigns.
