He originally studied computer science at Jagiellonian University (UJ) , though he later pursued theoretical physics and graduated with a Licentiate while also studying economic studies.

Political career

Mentzen began his political career in 2007 by joining the Real Politics Union (UPR) founded by Janusz Korwin-Mikke, serving for two years as the president of the party's branch in Toruń before suspending his activities within the party. He decided to re-enter politics after Paweł Kukiz's success in 2015, seeking to get on the electoral lists of Kukiz'15.

In 2017, Mentzen was elected vice chairman of Janusz Korwin-Mikke's New Hope party, at the time still called KORWiN. He had already held important functions in the party's structures, as he was the president of the Toruń district and the chairman of the party's scientific council. In the 2018 local elections, he ran for president of Toruń. He came in fifth place with 3.94% of the votes. In October 2022, he became the new chairman of the New Hope Party after Korwin-Mikke stepped down.

In the 2023 parliamentary elections, he ran as the leader of the Confederation Liberty and Independence in the Warsaw district. He obtained a seat as an X-term member of parliament, receiving 101,269 votes (5.91% of the votes cast in the district).

Mentzen is the most popular Polish politician on TikTok, with over 40 million views.

On 17 September 2023, less than a month before the 2023 Polish parliamentary election, Instagram, a subsidiary of Meta Platforms, banned Mentzen's account, which had over 340 thousand followers, in a move that Mentzen and various members of the opposing ruling United Right coalition branded as electoral interference.

Political stances Mentzen has been described as far-right by the media and critics. He has been a vocal critic of the European Union, calling it "totalitarian" and advocating for Poland's exit from the union. Mentzen has focused on economic matters, expressing concern about the tax burden and the level of welfare spending. These issues have become central to his political agenda, resonating with voters who share similar concerns about the country's fiscal policies. Mentzen's 20-point election platform for the 2025 Polish presidential election included "no Polish troops in Ukraine", "sealed borders", "low taxes", "stopping leftist ideology", "rejection of the European Green Deal", "energy security", "defending freedom of speech", and "freeing cryptocurrencies". He evoked controversy by calling for an end to free university tuition and banning abortion even in cases of rape. Mentzen wants Poland to withdraw from the European Green Deal and opposes LGBTQ rights. He later argued that the comments were taken out of a larger performance focused on how to reach out to voters.

In the same year, Mentzen prepared a sum of 100 bills ready to be legislated under the Sejm's jurisdiction. Among them were the proposals for a prison sentence for performing an abortion, the creation of "undissolvable marriages" for those who wanted them, the legalization of light corporal punishment of children by parents, and the ending of Poland's ban on promoting fascism and using hate speech. However, shortly after publishing them online, the bills were deleted, and the hosting for the website expired. When asked, he denied having authorship over most of the project.

Russian invasion of Ukraine Mentzen criticised the government's decision to impose a ban on Russian coal imports as part of the sanctions against Russia following its invasion of Ukraine. He states that this move was a wrong step by the Polish authorities, particularly considering the coal shortage and high prices the country is currently facing as of November 2022. Poland heavily relies on coal for its energy needs, with 66% of its energy mix coming from coal, and about 46% of Poles heating their houses with coal. Mentzen argued that the origin of the coal should not matter to consumers, emphasizing that the priority should be ensuring affordable and accessible heating options, especially for vulnerable individuals like the elderly.

2025 presidential campaign

Results of Mentzen. He obtained the highest result in gmina Dubicze Cerkiewne (32.86%) and the lowest in Sopot (7.06%) At the end of August 2024, Mentzen announced his intention to run in the 2025 presidential election and started a campaign. This action has been criticised by other politicians who state that, according to Polish electoral law, campaigns can only begin after the Marshal of the Sejm announces an act ordering the elections, thus making his campaign illegal. In response, Mentzen said that he is running a "non-electoral campaign" and that "it could just be a promotion of my face, my company, or a new product, that I have not yet announced".

During his presidential campaign he created on his YouTube channel a series called "Dzień z Mentzenem" in which he showed his average day as a member of the Sejm, candidate for President and business owner.

On 16 May 2025 he held his final campaign rally in Kraków before the mandated election silence went into effect at midnight 17 May 2025.
