About Superhuman

Superhuman provides AI-powered productivity features for email, document editing, and browser-based workflows, distributing functionality across tabs and apps rather than a single platform. The company operates at 1,001–5,000 employees across seven countries (Poland, United States, Mexico, Argentina, Brazil, Germany, Ukraine), with engineering and product as the primary investment areas. Active projects span LLM observability, evaluation pipelines, agent platforms, and data infrastructure—suggesting a transition toward AI-first product surfaces and away from hand-built, single-tenant solutions. Legal, compliance, and revenue retention feature prominently in both hiring and stated challenges.
