Wer wir sind

Gegründet wurde b4 im Jahr 2004 am Deutschen Forschungszentrum für Künstliche Intelligenz (DFKI) in Kaiserslautern. Unser Anspruch war kein geringerer als der, Technologie und Geschäftsprozesse auch für Unternehmen zugänglich zu machen, die bis dahin allein großen Unternehmen und Konzernen vorbehalten waren. Unternehmen aller Branchen und Größen sollten künftig effizient Geschäftsdokumente auf elektronische Weise austauschen und alle Vorteile von schneller und hochvolumiger automatisierter Kommunikation für sich gewinnbringend nutzen können.

Die Unternehmenskultur

Flache Hierarchien leben wir tatsächlich. Vom Youngster und Auszubildenden über Kollegen aus der Gründungszeit bis hin zur Geschäftsführung – jede Meinung zählt und jede Idee, die uns weiterbringt, ist für uns wertvoll. Wir sprechen auch Unangenehmes an, um daraus zu lernen und fortlaufend besser zu werden. Ebenso feiern wir unsere Erfolge und legen großen Wert auf ein gutes Betriebsklima. Leistung wird bei uns honoriert. Dabei machen wir keinen Unterschied zwischen Betriebszugehörigkeit und Rang.
