President Javier Milei appointed tech businessman Alejandro Oxenford as Argentina’s new ambassador to the United States. The decision comes a little over a week after former ambassador Gerardo Werthein became foreign minister following Diana Mondino’s removal.
“Thank you very much for your trust, President Javier Milei,” Oxenford wrote on X, confirming the news minutes after it was reported by some Argentine media outlets.
“I am convinced that, with focus and dedication, we will achieve significant impact, better positioning Argentina in the U.S. and the world more and more,” Oxenford added. He also said he was honored to have Werthein “as a guide” and Milei as “inspiration,” as well as “the ideas of freedom as my guiding force.”
Oxenford ended his post by including a quote he attributed to former South African President and human rights activist Nelson Mandela, although a quick Google search shows that the phrase seems to be apocryphal.
“Public service is not only an honor; it is also a responsibility,” reads the passage.
The Argentine Foreign Ministry formally announced Oxenford’s appointment in an X post on Tuesday noon. “His experience and commitment will strengthen bilateral relations and promote fruitful cooperation between both nations,” the post said.
Oxenford, who goes by the nickname “Alec,” has no previous diplomatic experience.
Starting in the late 1990s, Oxenford has created several companies dedicated to online adds. Among them are De Remate as well as unicorns OLX and Letgo. The last two became multinational companies with presence in several countries, with a special focus on the United States. They left the Argentine market in 2019, where local e-commerce giant Mercado Libre dominates the sector.
OLX is currently owned by South African holding company Naspers and based in the Netherlands. Letgo was acquired by marketplace OfferUp in 2020. De Remate no longer exists, after it was bought by Ebay.
Oxenford’s Wikipedia page also cites a Fortune Magazine article from 2014 that characterized him as a “CEO rock star of sorts” in South America due to his “staunch contrarianism.”
