Social Media

At Liderzy Jutra, Szymon and I handle social media: we create Reels, write scripts, and ensure our initiatives reach the widest possible audience. Previously, I worked on the "Mów to Głośno!" and "(NIE)USTRASZENI" projects—also managing social media—and served as project manager for the former. In my personal time, I am interested in rhetoric, photography, and art.

Franek

Leader of the City of Warsaw

Hi, I operate at the intersection of technology and sales: I understand how technical solutions work and can explain them in a way that makes people want to use them. At Liderzy Jutra, I am responsible for Warsaw—leading workshops and organizing conferences. Along the way, I took 2nd place in Samsung Solve for Tomorrow, 3rd place in the MAiR + PW × Elmark hackathon (securing automatic admission to the Warsaw University of Technology), and won the "Mission Mars" challenge at FoundersPath Camp.
