Tana Inc.

Tana Inc. is a software-as-a-service (SaaS) company founded in 2021 by Tarjei Vassbotn, Olav Kriken, and Grim Iversen. Headquartered in Palo Alto, California, USA, and Oslo, Norway, the company specializes in developing an AI-native collaborative workspace platform designed to enhance digital productivity for knowledge workers. The founders bring experience in advanced information modeling and large-scale productivity systems, aiming to address the limitations of traditional fragmented tools such as documents, spreadsheets, and emails.

Tana's primary offering is its subscription-based SaaS platform, which merges object-based note-taking, knowledge graphs, integrated AI agents, and voice workflow automation into a single proactive workspace. The platform operates under multiple subscription tiers including Free, Pro, and Enterprise plans, providing users with API access, customizable workspace management, and advanced integrations. After several years in stealth mode, Tana publicly emerged in early 2025, having built a strong user base and raising $25 million in Series A funding from prominent venture capital firms and angel investors.

Targeting individuals such as creators and productivity enthusiasts, as well as organizations including technology companies, consultancies, research institutions, and enterprise departments, Tana positions itself as a tool to streamline and automate digital workflows. The company remains independently operated and continues to develop its offerings influenced by an active and engaged community of users.
