The Founders
Patrick Knippel
Founder & MD
My path began with a MSc in Economics & Engineering from TU Berlin, followed by an MBA in Media Management at Steinbeis University, with studies in Berlin, New York, and Milan.
Professionally, I started at KPMG Germany as a senior auditor in the media industry before co-founding SCHMIDTz KATZE FILMKOLLEKTIV, producing 15+ films including the Oscar-nominated In Darkness (2012). I later built NOWTILUS, acquired by ROVI in 2011, bought back via management buyout, and—after being repositioned as a personalized ad streaming leader—sold to Equativ in 2022.
Leander Carell
Founder & MD
I began my studies as an Audiovisual Media Salesperson at the Public Broadcast MDR in Leipzig. Then, I studied TV Production Management at the BAF in Munich and finally completed the postgraduate EAVE Program for International Film Marketing.
Prior to StellaNordis, I co-founded Nowtilus, evolving it from a white-label VOD platform into a pioneering company in personalized ad streaming and server-side dynamic ad insertion. Under my leadership, Nowtilus attracted acquisition by ROVI and later strategic aquisition from global ad-tech leader Equativ.
I also bring creative expertise from film production, having worked on over 15 feature films, including the Oscar-nominated In Darkness (2012). My focus now is on leveraging technology and creativity to transform the future of digital media and advertising.
