Tana

Tana is a knowledge management and productivity software company founded in 2021 and headquartered in Oslo, Norway. The company was co-founded by Tarjei Vassbotn and develops tools aimed at individuals and teams who want to organize information in a structured, interconnected way.

Tana's primary product is a workspace application that represents all content as a graph of nodes, allowing users to tag, filter, and relate information across notes, tasks, and databases. The product has positioned itself in the personal knowledge management (PKM) market, competing with tools such as Notion, Roam Research, and Obsidian. More recently, Tana has described its product direction as an agentic meeting platform, where AI agents perform tasks such as creating documents, filing issues, and updating a knowledge graph during or after meetings.

Tana operated in a closed beta for an extended period before opening more broadly. The company has raised external funding, though specific round sizes and total funding amounts have not been publicly disclosed. The team remains small, with headcount in the range of tens of employees.
