About us

Callista offers consulting and engineering for demanding projects in the insurance, finance, industrial and life science sectors. We are an owner-managed company based in Zug, were founded in 2010 and operate with our team of around 80 experts. 

We are consistently focusing on the maximum impact of our performance for the long-term success of our customers in their projects.

We are convinced that four attributes are crucial for us as a company to consistently provide our customers with the impact they want: Mastery, Integrity, Caring and Agility. We call this principle the MICA-Mindset and define it substantively as follows:

MICA-MINDSET

MASTERY

competent & ambitious

We can only achieve the best result with the best people. After all, the success of a project always depends to a large extent on the people who work on it. That is why at Callista, we consistently rely on employees who are outstanding, competent and ambitious, both professionally and personally.

INTEGRITY

business-oriented & fair

Our unshakeable goal is always the sustainable economic success of everyone involved, including our customers and ourselves. This attitude has always been our driving force. That is why at Callista, we always think and act fairly with a focus on business success. After all, we can only be successful together if everyone involved benefits.

CARING

individual & personal

Tailor-made solutions for the individual challenges of our customers are important to us. This is the only way to generate maximum impact with pinpoint accuracy. That is why we rely on individually tailored solutions for projects, both in terms of the approach and the result, which we always develop in close personal discussion with our customers and experts.

AGILITY

lean & efficient

The leaner and more efficiently we achieve our goal, the more fulfilling the project work and the more satisfying the result for everyone involved. That is why at Callista, we organise ourselves internally and externally, and in everything we do, as lean and efficiently as possible.

Advisory council

Today’s problems are usually complex and require differentiated perspectives. Although the internet offers a sheer flood of information, filtering and assessing it requires personal experience and trust in experts who have already made this experience. The Advisory Council deals with practical technical issues. Topics such as data engineering, enterprise agility, software engineering and CRM are discussed. The Callista Advisory Council aims to bring together experts from different disciplines and backgrounds.
