Müge Arslantürk - Head of People
Hi there!
I'm Müge, Head of People at Entrix and Flexa, since July 2022.
I was born and raised in Turkey, moved to Germany in 2015 to start a new life here. I studied Psychology in my BSc and MSc thinking I will either stay in academia or go on a clinical psychology journey but then decided to move to business - a decision that I am very happy with since then!
The last 8 years I have worked at tech startups at very different size and development stages (with employee count of 20 to 200). I have learned a lot and grown both as a professional and as a private person in those years thanks to the amazing people I have worked with.
Here are some of those learnings I aspire to live by everyday:
The rest, we will figure it out together! Thank you for considering joining us, and I look forward to the possibility of working together!
