Fabienne Schlangen

Partnerships Manager

Fabienne is Caissa’s partnership manager and brand ambassador.

After university Fabienne found herself in the realm of HR and recruiting, namely in aviation engineering, where she gained 9 years of experience. Tech scale-ups have become an integral part of Berlin's culture, much like Currywurst and Kebap, which is why it was a natural decision for her to switch to the world of IT.

Fabienne values relationships and prefers them to lose connections. She always strives to understand problems from different perspectives first and then come up with creative solutions. At the moment, she is determined to take on her next challenge — making Caissa the best-known hiring partner on Berlin’s tech scene.

Office Manager

Stella believes that without smiles, the workplace would crumble.

Sitting in the driver’s seat of day-to-day activities that are essential to the operation of the office and supporting the team with all the running of the business operations, Stella finds joy in the fact that there is hardly ever a week that is identical to the other.

Having worked in management throughout her career, moving to Berlin to experience this in fast-growing industries seemed like the best decision.

Stella holds a Master of International Business Management from Berlin School of Economics and Law.
