Olav Kriken Sent 400 DMs. Four People Replied. Then Tana Found Its First Crowd.
The Tana CEO’s playbook began with an unglamorous bet: find four people, listen closely, and make the product worth talking about. His path from Norway’s west coast to Palo Alto is a study in community, conviction, and the useful art of doing what does not scale.
Tarjei Vassbotn Is Building a Memory for Work
After Google, wireless sensors and a conference-room pitch that went nowhere, Tarjei Vassbotn found his next problem hiding in plain sight: work remembers almost nothing.
Tana
Tana is an AI-native workspace that turns messy notes, meetings and voice memos into structured, queryable knowledge. Its signature feature, Supertags, lets any bullet point become a database record with defined fields, so notes double as a living knowledge graph that AI agents can read, summarize and act on. Founded in 2021 by ex-Googlers and productivity builders and based in Palo Alto with an engineering hub in Oslo, Tana raised a $14M Series A in February 2025 (led by Tola Capital), reaching $25M total funding after emerging from a stealth beta with a 160,000+ person waitlist.
