MOUZ is a German esports organization formerly known as mousesports. It began its journey in Dota back in 2007 and was among the first to enter the professional Dota 2 scene. It fields teams in many gaming disciplines and is particularly known for its successful Counter-Strike teams. In December 2011, the club announced the formation of a Dota 2 roster by signing the Western European team EBIN, which included Kalle Trixi Saarinnen, Weixin SingSing Yuan, Rexi, Mirsad DeMeNt Djokovic, and Visar twiSta Zimberi.

2012

By May 2012, the original roster had disbanded due to poor results. The revamped roster, centered around SingSing, included Alexandru ComeWithMe Crațunescu, Sivathaban 1437 Sivanthapillai, Alaan SexyBamboe Faraj, and Dominic Black^ Wrightmeyer. The team managed to qualify for The International 2012, but failed at the tournament itself, finishing last in their group, after which roster changes began again.

2013–2014

Over the next two years, the organization constantly rotated players in search of optimal synergy. They managed to return to Tier 1 only in 2014 after signing the Team Dog roster (Adrian Fata Trinks, Pascal paS Lomayer, Per Pajkatt Lille, Arif MSS Anwar, and Rasmus MISERY Filipsen). The revamped roster finished in 4th place at ASUS ROG DreamLeague Season 1, but at the main tournament of the year — The International 2014 — MOUZ finished in 11th–12th place. This poor result led to the loss of the roster: other major clubs took an interest in the key players, and the roster was disbanded.

2015–2017

From 2015 to 2017, MOUZ unsuccessfully attempted to assemble a competitive roster until it finally left Dota 2 in 2017.

2024

Seven years later, in 2024, the organization returned to the scene by signing the Team Tickles roster: Stefan Ulnit Gavril, Ondřej Supream^ Štarh, Nikko Force Bilokur, Ravdan NARMAN Narmandakh, Lukas Jonathan Bengan Hansson, and coach Daniel ImmortalFaith Moz.

The main achievement of the first half of the year was qualifying for the Riyadh Masters 2024, though the team finished only 16th there. After a string of setbacks at the fall tournaments PGL Wallachia Season 2 and BetBoom Dacha Belgrade 2024—where the team was among the first to be eliminated—management took drastic measures. In December, the club signed Lasha Nande Narsia, Thiago Thiolicor Coldeiro, and Tal Fly Aizik, but due to inconsistent results, major roster changes continued.

2025

During the first part of 2025, MOUZ focused on building a new roster, evaluating players and testing lineups in qualifiers. In April, the club signed Melchior Seleri Hillenkamp, who was joined in May by Kyalbek cutcutcut Tayirov, Abed Azel Abed Yusop, Nicholas Lim zeal Eng Han, and Marcel Ekki Golovienko. But this roster also did not last long due to yet another string of poor results.

In September, the organization made a second attempt to build a roster around Seleri. The new team members were Remko Crystallis Aretz, Zheng MidOne Ye Nai, Miroslav BOOM Bican, and Daniyal yamich Lazebny.

This roster brought the club its first significant results. The team finished as runner-up in FISSURE Universe: Episode 7, placed in the top three at BLAST SLAM IV, won PGL Wallachia Season 6, and cemented its success in December by finishing in 3rd–4th place at BLAST Slam V.

2026

In 2026, the team got off to a lackluster start, either finishing in mid-table or being eliminated early on. The team was also hit hard by the departure of Seleri, who retired. The exception was a small online event, PREMIER SERIES, where MOUZ finished in the top 3 with Alim aik Bespayev, who was temporarily replacing Hillenkamp.

In May, it was announced that Nikita Panto Balaganin would permanently fill the vacancy left by Seleri. By that point, MOUZ had already secured a direct invite to the Esports World Cup 2026. EWC MOUZ was one of the first teams to be eliminated, and the team failed to qualify for The International 2026.
