He co-founded Beat Saber, the breakout VR phenomenon that became one of the best-selling VR games of all time and was acquired by Meta in 2019. After exiting, Jaroslav doubled down on AI, co-founding BottleCapAI alongside Tomas Mikolov - the researcher behind word2vec and a pioneer in modern natural language processing. BottleCapAI builds efficiency-first LLMs: smaller, faster models designed for real-world B2B applications where speed and cost matter as much as capability. Beyond that, BottleCap AI invents brand new AI apps which tackle problems like potential biases inside LLMs and more.
