About DiQualis

At DiQualis, we value customer orientation, innovation and feasibility. We use our industry-specific knowledge and our creative ideas to find individual, feasible solutions for our customers. We achieve this by looking at the issue from our customers’ point of view, drawing on our experience from successful projects and always keeping your sustained capacity to act in mind.

We take your perspective

Customer orientation is not just a phrase for us – our customers are at the center of everything that we do. We place particular emphasis on your successful development and sustained stability. We achieve this through individual solutions and proximity – digitally, geographically, linguistically and in terms of content.


“There’s no such thing as ‘can’t’” – our maxim has proven to be a key success factor in all our projects. We will find a solution for anyone. And you can decide in which role we support you – from the resource supplementation to the interim management for your projects.

Wir sind effektive

„Geht nicht, gibt’s nicht“ – unsere Maxime hat sich als zentraler Erfolgsfaktor in all unseren Projekten bewährt. Wir finden eine Lösung, auch für Sie. Und Sie können entscheiden, welche Rolle wir dabei einnehmen – von der Ressourcenergänzung bis hin zum Interim-Management für Ihre Gesamtprojekte.

When Experience

We are specialists with extensive knowledge in various fields – and thus offer everything to suit your needs. As your business partner, we provide you and your company with measurable added value.

Our Management

Having the power to make strategic decisions enables unparalleled customer centricity, as short decision-making paths are possible for the benefit of all. The aspiration to provide the customer with all the advantages of a small and healthy organization with satisfied, committed employees motivates us every day.
Die strategischen Fäden in der Hand zu halten ermöglicht eine unvergleichliche Kundenzentrierung, da schnelle Entscheidungswege zum Wohle aller möglich sind. Der Anspruch, dem Kunden alle Vorteile einer kleinen und gesunden Organisation mit zufriedenen, engagierten Mitarbeitenden zur Verfügung zu stellen, motiviert jeden Tag aufs Neue.
Martin Seiler
Feasibility and added value are the goals that we pursue for our customers. That is why we place so much importance on taking our customers’ perspective and only introducing processes that can also be put into practice. Only if something new can be sustained over longer periods will it make a difference and create added value.
Mutual understanding is the basis for all our projects. This refers to the communication with the customer, of course, but clearly also to our internal cooperation. Open and active communication produces the best and most creative solutions. And that is exactly what we are good at: creating individual and effective solutions.

Gegenseitiges Verständnis ist die Basis für all unsere Projekte. Das bezieht sich natürlich auf den Austausch mit dem Kunden, aber ganz klar auch auf unsere interne Zusammenarbeit. Offene, rege Kommunikation bringt die besten und kreativsten Lösungen hervor. Und genau darin sind wir gut: Individuelle Lösungen schaffen, die einfach passen.
