Double
AI tool for researching and enriching sales leads automatically.
About Double
Double is an AI-powered lead research and enrichment platform designed for sales and marketing teams. It automates the process of researching prospects by using GPT to search the web and answer specific business questions about potential customers, eliminating manual Google searches. The tool allows users to research thousands of prospects simultaneously and can answer complex questions like whether a company is remote-first, SOC II compliant, or has specific technical infrastructure. Double distinguishes itself through its ability to enrich lead data with verified emails by aggregating multiple private data sources, which the company claims is more comprehensive than competing platforms. It offers a familiar spreadsheet interface for bulk operations and includes built-in web scraping and search tools. One limitation is that the tool relies on GPT-4 API capabilities, which means the quality of research depends on the underlying model's current knowledge.
