Our values include absolute transparency, both within the team and towards our customers. We maintain open communication and are not afraid to openly identify and address problems. With our experience, we know exactly where complications arise and openly speak up when something doesn't work.

As a team, we work as equals and welcome any input. Through regular events and our shared values and norms, we have become a close-knit team that trusts each other implicitly – whether at our home base or remotely.

Annika Gieselmann

Agile Coach, Master of Arts in Linguistics

Moderating and coordinating teams was already part of her daily work in student (writing) advising during her master's studies in linguistics, with a focus on communication. A significant advantage at that time was her additional training as a mediator, as it often required managing conflicts within the team or externally alongside her moderation duties.

In her further professional career, communication remained important, but agility also became an increasingly significant factor, shaping her roles as a Scrum Master, Agile Coach, and Project Manager.
