He has written books about Bitcoin, money and liberty and produced Stackuj Podcast from 2021 to 2026. His writing and talks are authored interpretations; employment at Trezor does not make him the company’s founder, a wallet engineer or an authority over the Bitcoin protocol.
Josef Tětek presents himself as an economist, writer, podcaster and Bitcoin educator. He does not make Bitcoin consensus rules, and visibility, a job title or published books cannot by themselves validate a particular economic, security or price claim.

SatoshiLabs’ official profile describes a background in Austrian economics and political philosophy and says he founded the Czech and Slovak Ludwig von Mises Institute in 2010. This records an intellectual orientation and organisational role, not neutral agreement across economics. [SatoshiLabs press kit — Josef Tětek biography] [ForkLog — 2023 interview on roles and ideas]
A July 2026 interview describes his work as ten years of active international education, suggesting an approximate start around 2016. That is a retrospective programme summary rather than an exact register of every article, job or public appearance.

He is associated with Bitcoin: Separation of Money and State, Bitcoin: The Return of Sound Money, and the Czech book Enemies of State, Friends of Liberty. The first two advance monetary and Bitcoin arguments; editions, translations and availability should be checked with each publisher.

His own site says Stackuj Podcast began in 2021 and featured conversations about Bitcoin, financial sovereignty and liberty. Its ending was publicly announced in July 2026; present-tense legacy website copy and an available YouTube archive therefore do not establish new episodes.

Signed articles remain in the Trezor Blog archive, and Tětek appears in media and at events including BTC Prague. A guest, speaker or author is not automatically the organiser, editor or independent verifier of every claim, product or partner on that platform.

Earlier profiles described him as a Bitcoin analyst or SatoshiLabs ambassador; current company pages name him Trezor Academy Lead. Those communication and education roles should not be confused with founding Trezor, managing the company or designing its hardware and firmware.

Trezor Academy began in 2023 and SatoshiLabs says Tětek has led it since launch. It is presented as a nonprofit, in-person series on Bitcoin basics and self-custody; the company’s 2024 review reported 21 countries and over 800 participants, which are dated organiser metrics.

Tětek’s work openly draws on a Bitcoin-only position, Austrian economics, personal sovereignty and criticism of state money. Readers should distinguish a documented fact, an economic interpretation, a normative view and communication by an employee of the commercial Trezor/SatoshiLabs group.

As checked on 3 September 2026, Trezor and BTC Prague list him as Trezor Academy Lead, while his public profile calls him an ex-podcaster. Stackuj remains online as a site and archive, but the podcast ended; job titles, Academy programmes and publication availability can change.
