Double
Double is a lead research and enrichment platform for sales and marketing teams. You upload a prospect list, and Double uses GPT to search the web and answer custom questions about each company or contact. Instead of manually Googling accounts, you define the criteria that matter to your outbound motion and get answers back at scale.
The product focuses on qualifying and enriching leads in bulk. You can ask whether a company is remote-first, SOC II compliant, B2B, building an API product, running a marketplace with payments, or shipping a mobile app as its core offer. Double returns sourced answers you can review alongside LinkedIn and email data in a table view.
Double also finds verified work emails by aggregating more than ten private data sources. The site positions this coverage as broader than tools like Apollo and RocketReach. Teams at Amazon, Indeed, and Gartner are shown on the homepage, and the company is backed by Y Combinator.
