K33

The research unit started in 2018 inside Arcane Crypto, which bought the Norwegian brokerage Kaupang Krypto in 2020 and listed in Stockholm in 2021 under the name Arcario. In 2023 the company brought its brokerage and research together under the brand K33, and the share now trades on Nasdaq First North under the ticker K33.

Torbjørn Bull Jenssen founded the company and leads it as chief executive, and he has advised the Norwegian central bank, the Ministry of Finance and Finanstilsynet on digital assets. K33 states that it works with major Norwegian banks, and the savings bank Høland og Setskog Sparebank is among the clients that K33 names.

Finanstilsynet authorized K33 Markets AS on 16 June 2026 under Article 63 of MiCA for custody and administration of crypto assets, execution of orders and transfer services for clients. K33 plans to add further services to the authorization over time and to serve private investors, companies, wealth managers and institutions across the EEA.

Norway applies MiCA as a member of the European Economic Area, so the authorization from Finanstilsynet works as a passport into the EU. The interim register of ESMA lists Sweden, Denmark, Finland and Greece as passport countries, and in July 2026 K33 reported that it had also completed the passport process for Germany.

The K33 Vault keeps crypto assets for long-term clients with withdrawal rules that each client agrees individually, and K33 helps families plan how crypto assets pass to the next generation. Clients reach the custody team through a dedicated support line instead of a chat bot.

K33 Loans lets clients borrow USDC against bitcoin as collateral and convert the loan into Norwegian kroner, euros, dollars or five other currencies. Each loan has its own size, term and loan-to-value ratio, and a margin call or liquidation follows when the bitcoin price falls below the agreed thresholds.

K33 is a crypto broker, custodian and research house from Oslo that serves private clients and institutional partners across Europe, the Middle East and Africa. Its subsidiary K33 Markets AS holds a MiCA authorization from Finanstilsynet, and the parent K33 AB is listed in Stockholm.

K33 Research publishes weekly market analysis on bitcoin, half-year round-ups, a year in review and the Nordic Crypto Adoption Survey, which asks investors in the Nordics how they use crypto assets. Professional investors subscribe to K33 Research Pro, and the reports are also available as a podcast.

K33 AB launched a bitcoin treasury strategy in May 2025 and holds bitcoin on its own balance sheet to support new products and partnerships. In February 2026 it agreed to buy a stake of about 46 percent in Sixty Six Capital, a Canadian bitcoin treasury company listed on the CSE.

The shares of K33 AB are issued under Swedish law, trade on Nasdaq First North Growth Market in Stockholm and carry one vote each. Euroclear Sweden keeps the share register, and investors outside Sweden buy the share through brokers with access to the Stockholm market.

K33 Markets is the trading service where clients buy and sell crypto assets with deep liquidity and no trading or withdrawal fees, as K33 states. Large orders go through the OTC desk at a price agreed in advance, and every client gets direct contact with a named client manager.
