Jonathan “Maravilla” Alonso and his OnlyFans: the Olympic boxer sponsored by the platform

Does Jonathan Alonso have OnlyFans?

Yes. Boxer Jonathan Alonso, known as “Maravilla,” has had a profile on OnlyFans (nicknamed the “página azul,” or blue page, in Spanish-speaking countries) since early 2023, when the platform began sponsoring him. His content is about sport: videos of his training sessions and his daily life. Relevo reported in December 2023 that he offered it for free, and El Periódico ran an interview with him in February 2024 in which he explained how the deal came about.

Who is Jonathan Alonso?

He was born in the Dominican Republic and grew up between Avilés and Gijón, according to La Nueva España. He started boxing at 16 almost by chance: an acquaintance talked him into going along to a newly opened gym where only boxing was taught, he told AS. Five years later, at 21, he competed at the London 2012 Olympics, which he considers the best experience of his life, he told Hola.

As a professional he was the first Spaniard to sign with a promoter in the United States, and he fought at the Barclays Center in New York and in Times Square. In April 2023, with a record of 22 wins and 2 losses according to AS, he fought for a WBA continental belt at the WiZink Center in Madrid.

Outside the ring he has a career as an actor. After one line in a Bollywood film, he appeared in Agustí Villaronga's El rey de La Habana and in series such as Gigantes and Welcome to Eden (Bienvenidos a Edén); Hola also mentioned the film Reversión, with Belén Rueda and Jaime Lorente. In 2024 he published his autobiography, Uno entre un millón, and he owns a beauty center in Madrid frequented by celebrities, according to AS.

His OnlyFans sponsorship

He told El Periódico that the offer came in early 2023, two months before that fight at the WiZink Center, and that once he learned the platform was already working with Jennifer Miranda and Ilia Topuria he wanted to join. He described the money as an “exorbitant financial boost” compared with other sponsorships: it paid for supplements, physiotherapy, recovery sessions and a training camp with his whole team in the Canary Islands to find good sparring partners.

For his channel he employs a camera operator who films his training like promotional clips, and he also shares his achievements and daily life. He admitted that at first he faced a lot of criticism, especially when he showed up at a weigh-in dressed head to toe in the brand's clothing, because people did not understand it. Since then he wears its merchandise on the street to normalize it.

Relevo listed him, along with Miranda, Topuria and fencer Yulen Pereira, among the Spanish athletes OnlyFans began sponsoring in 2023.

From La Velada del Año to film sets

In recent years he has become well known among young audiences as the trainer of the content creators who fight at La Velada del Año, Ibai Llanos's event. According to La Nueva España, he started with singer Abraham Mateo and later worked with Plex and RoRo; for the July 2026 edition at La Cartuja in Seville he trained Plex, Marta Díaz, RoRo and Fabiana Sevillano. He does it at The Boxer Club in Madrid, together with Javier Pardo, according to Hola.
