Argentine political operative, 44 years old as of December 2025, who has become one of the most prominent right-wing campaign strategists in Latin America. The Latin American left calls him the "prince of darkness".
Mr Cerimedo runs Numen, a political-marketing agency based in the Puerto Madero district of Buenos Aires, along with an associated "training academy" (the Numen Academy) and a news website, La Derecha Diario (The Daily Right), which promotes right-wing and libertarian ideologies. His business partner at Numen is Brad Parscale, Donald Trump's former campaign manager, who manages the firm's technical operations.
Mr Cerimedo's first brush with prominence came in Brazil in 2022. He hosted a live-stream entitled "Brazil Was Stolen" days after Jair Bolsonaro lost re-election to Lula da Silva, alleging that old voting machines had been fiddled with to swing votes to Lula. He was investigated by Brazilian police but never charged.
His wife pushed him to get involved with the presidential campaign of Javier Milei. He worked on digital-media strategy with Santiago Caputo, who remains one of Mr Milei's top advisers. Mr Cerimedo claims it was he who encouraged Mr Milei to bring a chainsaw on stage at rallies as a symbol of his plans to slash spending. He also secured an interview for Mr Milei on The Tucker Carlson Show when Mr Milei was trailing in the polls and at risk of not reaching the second round—a timely boost that also made Mr Milei an international sensation and caught the attention of Mr Trump. Mr Cerimedo has since parted ways with Mr Milei after falling out with his inner circle.
In 2022 Mr Cerimedo worked on the campaign to defeat the attempt to install a controversial left-wing constitution in Chile.
Among the graduates of Mr Cerimedo's Numen Academy is Catalina Paz, the daughter of Bolivia's president, Rodrigo Paz. She now advises her father's government. Mr Cerimedo worked on media strategy for the Paz campaign, helping to turn Bolivia away from the left-wing MAS for the first time in two decades. He continues to work with Mr Paz as a senior adviser.
Mr Cerimedo managed the presidential campaign of Nasry Asfura in Honduras. He says he co-ordinated Donald Trump's endorsement of Mr Asfura with Dick Morris, a friend and strategist who works on Latin America. He believes the endorsement gave Mr Asfura's campaign the boost it needed. He shuttles between Bolivia, Honduras and his home in Buenos Aires.
Mr Cerimedo says he rejects accusations of using "troll farms" or running smear campaigns with "bot" accounts, claiming instead that he merely monitors online conversations and uses that information to influence public opinion with tailored messaging.
