Tempest is a company brain for startups, starting with founders. It keeps the company’s evidence, assumptions, decisions and outcomes connected as a living state, including why decisions were made and what they depended on. Today, founders can talk to Tempest, build structured company knowledge, retrieve relevant context across conversations, preserve outdated or resolved knowledge instead of losing its history, and turn company state into things like an editable Living Roadmap. The larger goal is judgment, not just memory. As new evidence arrives, Tempest should understand which assumptions and previous decisions it affects, preserve the original reasoning, and surface what may need to change next.
