What Double does

Double is a Redwood City, USA-based SaaS company founded in 2022 that builds an AI-powered lead research and email verification platform for B2B sales and marketing teams. Its core product uses GPT to automatically research prospects on the public internet and answer structured qualification questions — for example, whether a target account is remote-first, SOC II compliant, building an API, or operating a marketplace — replacing the manual Googling workflow that outbound sales reps typically perform. A complementary email verification capability aggregates more than 10 private data sources to find and verify prospect contact details, with the company positioning this layer as more comprehensive than incumbents Apollo and RocketReach.

The platform is delivered as a single self-serve web application at usedouble.com, combined with a Calendly-driven demo funnel for sales-assisted conversion. Customers targeted are horizontal: sales teams, marketing teams, and B2B companies running outbound campaigns. Named enterprise design partners include Amazon, Indeed, and Gartner. Revenue is generated through a SaaS subscription model, although pricing is not publicly disclosed and customers are routed through demos rather than transparent self-serve plans. The company is privately held, backed by Y Combinator (with a disclosed $500,000 funding event in April 2023), incorporated as Double Technologies, Inc., and operates with a small team of 1–10 employees. Co-founders are Gonzalo Espinoza Graham and Wesley Yue, and the company has not yet announced an API, SDK, or ecosystem integrations.
