Four people replied. That was the whole crowd. Olav Sindre Kriken had sent roughly 400 personal messages on Reddit, looking for people frustrated with tools Tana hoped to improve upon. A one-percent response rate has the sterile look of failure in a spreadsheet. In the hands of an operator, it can look like a guest list.
Kriken decided the four would be treated as the most important people in the company. At that moment, they were. They received lifetime access, a Slack room, regular sessions with the founders, and something more scarce than free software: evidence that their attention mattered. Within weeks, the four asked to invite others. Ten apiece made 40. The room widened without losing the feeling of a room.
By the time Tana opened beyond its closed beta in February 2025, more than 160,000 people had joined the waitlist. Thirty thousand had tested the product during nine months of beta, and the Slack community counted 24,000 members. The numbers were newsworthy. The mechanism was almost quaint: write to people, listen carefully, remember what they said.
A computer in pieces
Kriken grew up in a town of about 10,000 people on Norway’s west coast, where childhood meant soccer, skiing, nature, and considerable time outside. Curiosity arrived early. When he was 10, his mother brought home a computer from the bank where she worked. He wanted to understand it, so he took it apart. Her alarm was immediate. His interest in technology proved more durable.
He has described himself as energetic then and energetic now. His birthday falls on December 22, making him one of the youngest in his Norwegian school year. Kriken believes that having to claim his place among slightly older classmates shaped him. It is a small autobiographical theory with a founder’s logic: a disadvantage becomes a rehearsal.
Long before Palo Alto, there was Ørsta. Kriken founded the data-driven marketing agency Racer there in 2011. The company merged with IT business Avento in 2017, and Avento was acquired by Visma two years later. Kriken went on to lead Visma Digital Marketing within the operation. It was an education in the unromantic side of digital work: traffic, conversion, positioning, and the stubborn gap between a product existing and anybody caring.
The first four get the good chairs
Tana was built with Tarjei Munthe Vassbotn and Grim Iversen, two founders with deep experience in product, information modeling, and the long-running effort to make computers less clumsy around human thought. The product combined connected notes, structured objects called supertags, a knowledge graph, voice capture, and AI workflows. Its promise was simple to say and difficult to engineer: work should not disappear into a pile of documents the moment a meeting ends.
The connected model changes the unit of work. A person, decision, project, or task can remain itself wherever it appears, rather than becoming another copy stranded in another file. Voice notes can become structured actions. Meeting context can travel into a proposal or project plan. Search becomes less about remembering which document swallowed an idea and more about following the idea through the system. For Kriken, this is where the company’s growth story meets its product story: both depend on connections that preserve context instead of flattening it.
Kriken’s territory was where product met people. During Tana’s first year, he personally onboarded roughly 300 users. The intimacy served two purposes. It exposed friction before a dashboard could smooth it into abstraction, and it gave early members a credible sense of ownership. Their feedback did not land in a polite void. It could change the thing they were using.
The human flywheel
This is the useful part to steal. Community is not a distribution channel with friendlier typography. It is a reciprocal arrangement. People contribute attention, patience, ideas, bug reports, and social proof. The company must return access, responsiveness, and visible progress. If the exchange is lopsided, the community becomes an audience. Audiences are free to leave after the show.
Tana’s early group did the opposite. Members asked to bring friends. Invitation was not bolted onto belonging; it emerged from it. That progression, four to 40 to hundreds, made the eventual 160,000 look less like a launch stunt and more like accumulated evidence.

Capital follows the conversation
Investors noticed. Tana announced $25 million in total financing when it emerged from stealth, including a $14 million Series A led by Tola Capital. The round gave the company a reported $100 million post-money valuation. Its backers included Lightspeed Venture Partners, Northzone, Alliance VC, and firstminute capital, alongside technology founders and operators.
Kriken frames investor selection as a choice of people rather than logos. The distinction fits the larger pattern. A famous firm cannot debug a relationship. A partner can. One early investor relationship began at a small San Francisco meetup only weeks after the first users entered Tana. Product fluency and belief in the mission mattered more than the shine of a name on a slide.
In 2026, Kriken was publicly identified as Tana’s CEO, with Vassbotn moving into the CIO role and Iversen serving as CAIO. The company’s language shifted too. Tana had won Product Hunt’s Product of the Year and Launch of the Year, but the team decided the market was moving faster than its existing approach to agents. Configurable agents pleased power users while creating complexity, duplicated content, and too many sources of truth. Tana began rebuilding around AI coworkers that can share the context of meetings and decisions.
Stay manual until you know what deserves to be automated. Speed applied before understanding merely produces confusion more efficiently.
Motion, progress, and the protected hours
Kriken’s management vocabulary draws a line between movement and progress. A team can produce activity all week without advancing the work that matters. He is skeptical of consensus when it disguises an absence of direction. Alignment on where the company is going matters; agreement on every turn does not.
That preference for explicit boundaries appears in his daily life. Living in Palo Alto while much of Tana’s team works in Norway means he starts around 5:30 in the morning. In the early evening, roughly 5:00 until 7:30 or 8:00, his team knows he is with family. Only direct reports and co-founders can break through his phone’s focus mode, and then only when the matter is genuinely urgent.
He and his wife have three children. Kriken describes her as his partner in the family’s most consequential venture, and the two try to present one voice to their children even when arriving there requires private debate. He also plans individual weekly time with each child. A “dad date” can be a shared series watched only together, passes with a soccer ball, a drive to practice, or time on the floor playing Barbie. The children do not know the ritual has a name. The point is not ceremony; it is undivided attention.
One line he returns to is small enough to fit on a Post-it: You don’t have to have it all figured out.
It applies cleanly to parenting, and suspiciously well to company building. Presence can beat polish. The important move is to remain available to what the situation is teaching.

The river changes course
Tana takes its name from a Norwegian river. The metaphor is almost too tidy: information flows, branches, floods its banks, and refuses to stay inside a rectangular document. The founders’ aspiration is to give that movement shape without freezing it. Meetings should create work, not merely produce recordings. Decisions should retain the reasons behind them. AI should operate with shared context instead of appearing at the edge of every application like an eager stranger.
Kriken has now moved through four companies, from marketing services on Norway’s west coast to an AI workspace headquartered in California. He remains publicly attached to Ørsta, a local patriot working nine time zones away. The geography matters. It explains the early mornings, the Norwegian team, and perhaps the preference for building social density before scale.
The polished version of a startup story begins with a market insight and ends with a financing round. The lived version is stranger and more useful. A child takes apart a bank computer. An agency starts in a small town. Four strangers answer messages. A Slack room becomes crowded. An award arrives, and the company decides to rebuild anyway.
Kriken’s story offers no magical growth lever. It offers something more durable: attention, applied repeatedly. The first four people are not a rounding error on the way to 160,000. They are the entire method in miniature.
