About
Marek is the CEO and founder of two Prague-based companies: Keen Software House, an independent video game development studio, and GoodAI, a general artificial intelligence R&D company. Keen Software House is best known for its sandbox best-sellers Space Engineers (1.5mil+ copies sold) and Medieval Engineers. Marek started the company as the sole programmer but later took on a leadership role when he transitioned to CEO. Marek has been fascinated with artificial intelligence since childhood. After the success of the Keen Software House titles, Marek was able to personally invest $10M USD in a new general AI research project trying to build human-level artificial intelligence.
