What does Double do?
Double is an AI tool that automates sales prospecting and lead research. Instead of manually searching for information about potential customers, sales teams can use Double to automatically research leads across the internet. The tool answers specific qualification questions about companies—like whether they're remote-first, SOC II compliant, or B2B-focused—by using AI to search and analyze web content. This saves hours of manual research and helps salespeople understand their prospects better before reaching out.
The tool works by processing lists of prospects and using GPT-powered research to gather information from various online sources. It also finds and verifies email addresses by aggregating data from more than ten private sources, claiming to be more comprehensive than services like Apollo and RocketReach. What makes Double stand out is its ability to handle thousands of prospects at once and provide specific, actionable answers to custom qualification questions that sales teams define.
Sales and marketing teams at companies like Amazon, Indeed, and Gartner use Double to improve their outbound campaigns. The tool helps them create highly targeted messages that convert better by providing detailed prospect insights. It's particularly useful for teams running large-scale outreach campaigns who need to research and qualify leads efficiently without manual work.
