Stefan was both amazing and incredibly important for me and my company. He helped me see clearly when I was unsure of the path, with specific tips on how to improve and actionable items to unlock me. He has an amazing overview of the overall landscape and thus can give you recommendations that actually fit your company, rather that "one size fit all" solutions that would probably not work for you. If you need a mentor you should talk to Stefan while he is available, and I'm sure he will unlock progress for your company. Thanks for everything Stefan!
