“Coming together is a beginning, keeping together is progress, working together is success.”
Henry Ford

Wilhelm Pfeifer was born in 1974 in Graz, Austria. After graduating at Handelsakademie in Villach he started his career as a professional soldier to the Austrian army. In the year 2000, after his career as officer, he changed over to the private sector by joining the first alternative telecom provider in Austria, CyberTron Telekom AG.

After various sales and management functions at CyberTron Telekom AG as well as in the Austrian Kapsch Group, Pfeifer devoted himself completely to the development of today's ASCUS Group International from 2005 onwards and recorded numerous sales successes in the international telecommunications market in Scandinavia, Central and Eastern Europe. He played a decisive role for some minor and larger mergers in the Austrian telecom market in the period from 2006 to 2009. In 2010, the successful exit from the established telecommunication group followed. Since the year 2000, Pfeifer has maintained a continuous and intensive partnership with Colt, which also led him to develop his Swiss company, AAA Sales & Management GmbH, the largest and growing Colt partner in Europe. In 2011, 2014 and 2016 the company was awarded the Colt Sales & Marketing Award, which is awarded for the strongest growth.

He also discovered early on his love for sport and especially for basketball and ice hockey, which has resulted in Pfeifer having been working for the development of this sport since the year 2005 as part of the North-East Switzerland basketball federation. Since 2011 the company AAA Sales and Management GmbH has also been present as a supporter in the Kristallclub, a donor association in favor of EV Zug.

Mr. Pfeifer is distinguished by the fact that he understands the language of the customer and has the ability to put himself in the position of the customer. With the knowledge gained thereby he then tries to develop the requirement of customers into a value-creating solution. Anyone who counts on his network will be well looked after and will also benefit from other people in his network.

"Am Ende wird immer alles gut"
Wenn es nicht gut ist,
ist es nicht das Ende.
Oscar Wilde

Florian Frühstück wurde 1976 in Eisenstadt, Österreich geboren. Während des Architekturstudiums begann der Autodidakt mit der Web Programmierung und beschäftigte sich fortan intensiv mit der Erstellung von Internetauftritten. Da das Leben stete Veränderung ist, führte ihn sein Weg vom Website Design immer mehr zur Programmierung und Implementierung von Content Management Systemen und anschliessend wieder zurück zur Frontend Programmierung. So sind nun eben wieder  HTML, Javascript und CSS die Steckenpferde aus den Anfangsjahren sein Haupt Themengebiet. Zusätzlich beschäftigt er sich schon mehrere Jahre mit online Marketing, SEA und SEO.

Nachdem AAA Sales & Marketing bereits mehrere Jahre mit Florian Frühstück zusammen gearbeitet hat und mehrere Internetauftritte gemeinsam entwickelt wurden, übernimmt er nun auch die online Marketing Agenden für uns.

In seiner Freizeit widmet er sich intensiv seinen drei Kindern und betreibt regelmässig Sport (Basketball, Tennis und Trail-Laufen).
