TheLion.AI is an independent collective of programmers, lecturers, startup founders, and researchers focused on advancing healthcare through artificial intelligence. Originally founded at Gdańsk University of Technology, we now span multiple universities and have grown into a community of over 70 people.
The same founders are now building its US home in Atlanta: open-source projects, monthly meetups and workshops, and NVIDIA-certified training for companies — with the papers and tools shared across both places.
