Heritage

Siux was founded in Spain in 2012 with the aim of becoming one of the leading padel brands. In 2013 it presented its first full racket collection, moved production to Spain and launched the Diablo, which became its signature model and is still in the range today. Earlier models such as the Optimus gave the brand its first commercial success.

In 2015 Siux built its own factory in Spain so it could control production quality. By then the catalogue had grown to more than 20 models. The early signing of Chico Gomes, then ranked in the World Padel Tour top ten, gave the brand its first international profile.

From 2017 Siux expanded outside Spain into Africa, the Americas and the rest of Europe. In 2018 it sponsored the wheelchair padel players Antonio Carneros and Rubén de Diego.

For much of the 2010s and early 2020s Siux was part of the same group as Padel Nuestro, the Madrid-based padel retailer that began with a shop in Murcia in 2010. The group, later called 360º Padel Group, was led by Íñigo Colomina. In July 2022 Ergon Capital took a majority stake in 360º Padel Group, which then owned both Padel Nuestro and Siux.

In February 2021 Siux became the official racket of the Spanish Padel Federation for two seasons, under chief executive Nacho Martín Acicoya. The same month it announced a padel court manufacturing project with its own factory, with the first installation of five courts at Padel Club Thisted in Denmark in April 2021, and in December 2021 it installed its first courts in the Americas.

2022 brought the brand's biggest player signings. Franco Stupaczuk joined in January on a three-season deal and received his own racket, the Electra ST1, in May. In July Siux signed Sanyo Gutiérrez, then world number six, for three seasons, and he played the Diablo Revolution. Also in summer 2022 Siux became official sponsor of the Portuguese Padel Federation, supplying clothing and bags to its national teams. In 2022 the brand marked its tenth anniversary.

In February 2023 Siux agreed a deal to sell its rackets through Tennis-Point stores in Spain, and between 2023 and the first quarter of 2024 it entered 35 new countries, 18 of them in Africa and ten in Asia, including Japan.

On 25 July 2024 Siux completed its separation from Padel Nuestro and became part of a new company, Siux Brands World S.L., with bases in Madrid and Miami and Íñigo Colomina as executive president. The company said it had grown by 100 per cent in the previous year and was present in 75 countries. In October 2024 the young Argentines Leo Augsburger and Tino Libaak moved to Siux from NOX, and Álex Chozas also joined. Sanyo Gutiérrez left for SET Sport in January 2025, and Sofia Araújo signed from Bullpadel the same month.

In January 2025 Siux updated the Electra (ST4) and Fenix (Fenix 5) ranges and launched Valkiria, its first range designed for women players. In October 2025 it presented a new logo and identity under the line "Cross the line" at an event in Madrid, together with the 2026 collection. It has since added the Astra, Trilogy and Beat ranges and Siux Turf, an artificial grass surface for padel courts.

In February 2026 Franco Stupaczuk, then world number six, renewed with Siux until 2029 at the brand's Madrid flagship store. In April 2026 Leo Augsburger signed a contract running to 2040, 14 seasons, which the Spanish padel press described as the longest contract in the sport's history.
