# Tettra

> Tettra is an AI-powered internal knowledge base built for teams that live inside Slack and Microsoft Teams. Founded in Boston in 2015 by Andy Cook and Nelson Joyce, it lets companies curate documentation into a searchable wiki and answer repetitive questions instantly through an AI bot named Kai, which searches verified content and routes anything it can't answer to the right subject matter expert. Positioned as a simpler alternative to Confluence and Notion, Tettra reached roughly $3.2M in annual revenue with about 548 customers before being acquired by Canadian software firm GSoft (now Workleap) in October 2023.
