The KNIME Team

Trevor Kaufman

Ralf Grüßhaber

Ralf Grüßhaber is our CFO. He has seen both small and larger companies before and, most importantly, the transition as well. Oddly, though, he is also a loyal VfB fan - which explains why Christian supported bringing him on board.

Jennifer Ostyn

Jennifer Ostyn, our SVP Revenue refuses to move from peach country to the Insel Reichenau but it’s a tad understandable given the size of her family and her passion for Southern Baked Pies. Konstanz doesn’t have that - and neither is there a Peach Drop.

Iris Adä

Iris Adä is now our VP Data & Analytics but originally started out creating data with KNIME and wrote the data generation nodes (check out her famous "The new Iris Data" paper). She then went on working with customers in pretty much all possible roles and also setup support at KNIME. If she doesn't know what data sits where (and what it means), nobody does.

Christian Birkhold

VP Product and therefore responsible for all things “product”. In his free time he is a suffering, pessimistic, bitter VfB Stuttgart fan. But he claims it’s easier to bear if he gets mocked about it, so we make sure he gets plenty of that.

Nora Ohlerich

It’s at somewhere around 100 or so people that "HR" becomes a real thing. Luckily for us, we managed to find someone who interprets human resources not as "employee life cycle management" but focuses on the 'H' in 'HR'. Together with Katrin, she co-leads HR at KNIME. Unfortunately, we cannot reveal any of Nora's secret desires (besides the fact that she eats carrots in masses) as she would quickly file an HR case.

Katrin Koch

We’re glad to have Katrin as our Director HR. She supports all people-related matters across KNIME, co-leading HR together with Nora. When she’s not keeping our HR world running smoothly, Katrin enjoys playing board games and exploring new recipes in the kitchen. And her fun fact? She was once a member of a Schützenverein - so she brings not only precision and focus to HR but also a steady aim!

Sasha Rezvina

Sasha Rezvina is our VP Marketing and was originally brought on board to translate geek-speak into real-speak. But since she does that in her sleep we are now curious to see how her new found improvisation skills on the piano will find their way into our marketing material as well! 

Shyam Sundar C S

Shyam leads Tech at KNIME, where he focuses on building scalable platforms, simplifying complexity, and helping teams move from ideas to execution. He brings a systems mindset to both tech and team dynamics, with a steady hand in moments of ambiguity.
