What Martin Wiesend Die Kundendienst-Trainer does

Martin Wiesend Die Kundendienst-Trainer, operating as KDT GmbH, is a privately held German training institute headquartered in Heidenheim an der Brenz, Baden-Württemberg, founded in 1998 as the first institute in Germany exclusively focused on the technical service sector. The company serves industrial enterprises across mechanical engineering, plant engineering, automotive, medical technology, building technology, and IT, with named reference customers including ThyssenKrupp, Claas, Viessmann, Zeiss, Voith, KraussMaffei, and Fresenius. KDT delivers a structured curriculum across five buyer segments: field service, internal service, technical trainers, service sales, and service management.

The core product portfolio centers on the TTxTT (Train the Technical Trainer) certification, a 10-day flagship program described as the only university-affiliated technical trainer certification in Germany, alongside KKT (Kundendienst-Kompetenz-Training) for service competency, a Nonverbal Communication Toolbox built on Michel Grinder's methodology, and a modular seminar catalog. TTxTT and KKT are registered word-image trademarks. Delivery occurs through three channels: open seminars with individual enrollment, customized inhouse corporate seminars delivered on-site or virtually, and an e-Training/online seminar line including the Conducting Technical Training Online TTxTT program. Training content is offered in 8 languages, with over 50 seminars and workshops and 150 training formats delivered annually to more than 1,500 participants, anchored by the recurring Forum TT (Forum Technisches Training) community event scheduled for June 2026 in Schwäbisch Gmünd.

KDT operates a professional-services revenue model with quote-based, multi-year engagements priced per cohort and customization level rather than via publicly disclosed list pricing. Sales are direct and relationship-led across both open enrollment and enterprise inhouse training, supplemented by community-led demand generation through Forum TT and peer testimonials. The firm holds TÜV Rheinland adult education certification (Zertifikats-ID 0000086140) and GDPR/DSGVO compliance. The company underwent corporate restructuring in February 2023, was renamed KDT GmbH Die Kundendienst-Trainer, and appointed Emre Günes as Managing Director alongside founder Martin Wiesend.
