Pitann debuted in 2006, portraying a
luchador enmascarado character, named Diego Latino. During this time, he was part of the La Familia stable where he frequently teamed in different German promotions with Baca Loco,
whose mask he won in July 2008. He then began regularly appearing for
Westside Xtreme Wrestling (wXw), under the ring name Karsten Beck. However, it was not until 2011, when he joined The Mind, a stable led by Adam Polak, that he had more of a prominent role. In March 2011, he and Polak defeated Oberhausen Terror Corps (
Bad Bones and Carnage) to become
World Tag Team Champions, enjoying a seven-month reign. Beck and
Big Van Walter (Polak's replacement) dropped the title in
Mannheim to The Wanderers (Jason Hendrix and
Jay Skillet), who were used as transitional champions, in order to get the title onto the Sumerian Death Squad (Michael Dante and
Tommy End), a tag team previously associated with The Mind. The following year saw him reach the quarter-final of 16 Carat Gold, in which he almost got away with cheating to beat
El Generico, and during the summer was involved in title shots for Generico's
Unified World Wrestling Championship. In 2013, Beck reached the semi-final of 16 Carat Gold, where he was defeated by
Zack Sabre Jr.; it would turn out to be his career best in the tournament. By the end of the year, he started teaming with
Sha Samuels, which continued into 2014, but they were only granted one title shot, in a defeat to Hot & Spicy (
Axel Dieter Jr. and
Da Mack).{{cite web|url=https://www.cagematch.net/?id=1&nr=56740|title=wXw Drive Of Champions Tour: Hamburg ==Death==
