10+ years: I've served on the WMF Board since 2015. I am a trustee and vice chair of Escola S.A., a public traded company in Poland (a leading mobile apps developer). I have also served on the board of Copernicus Science Center (with 1 million visitors per annum) since 2011.
I don't have executive experience at this scale. I do have executive experience though. Currently, I run a university department with 20 people, and solely decide about a research budget of ~2.5 million USD. I founded, scaled and sold ling.pl (the largest online dictionary in Poland, with 15 million monthly views at top). I co-founded InstaLing, an educational platform currently used by over 220 thousand students weekly, where I lead a team of 15 people. 1998-2004 I was also an ED of an NGO (Collegium Invisibile, from the Soros Network) with an annual budget of approx. 65 thousand USD.
10+ years: I consult on strategy professionally, and currently I'm a chief community strategist at Foap, a startup with 3 million users aimed at making content creators get a more fair share of royalties. As a professor of management, I held various long-term appointments at top schools, including Cornell University, Berkeley, MIT, or Harvard (where I'm currently a faculty associate at Berkman-Klein Center for Internet and Society). I serve as an advisor to Women's Strike, a Polish movement combating draconian reproductive laws limitations (strictest in EU). I've also served on the honorary committee of Polish Pride Parade for many years.
Partly: I am a white CIS, straight man, which already puts me in a highly privileged group worldwide without any doubt. However, for many years I lived for about 20 USD per month, could not travel (I still remember the first time I flew an airplane and went to a Western country, already as an adult... The smells, the colors - shocked me :) It was not until I was way above 30 that I stopped treating all Westerners as smarter and better educated by default...), and I come from a region historically rarely represented in the structures of power.
Yes: My home is in Poland, and I also lived for 2+ years in the US and Denmark.
Yes: I grew up in communist Poland. I had to constantly watch what I was saying not to get my parents in jail, and I know what actual censorship is (also, I'm pretty good at reading double talk, be it corporate PR or state propaganda). Depressingly enough, my country nowadays is slipping into an authoritarian regime again.
