Tom Koska

Tom Koska is a co-founder of SF Tensor, an artificial intelligence infrastructure and high-performance computing startup based in San Francisco, California. Founded in 2025, the four-person enterprise participated in the Y Combinator F25 batch and secured financial backing from Susa Ventures, Paul Graham, and senior executives from Neuralink and AMD. Koska is currently pursuing a Bachelor of Science degree in Computer Science, a rigorous academic program he is scheduled to complete at the age of sixteen. Prior to establishing his current venture alongside his two brothers, he spent several years researching and developing foundational world models and optimizing high-performance computing systems for complex machine learning workloads. His current technical focus centers on building hardware-aware programming languages like Emma Lang, developing advanced compute kernel optimizers, and engineering elastic cross-cloud orchestration tools to accelerate artificial intelligence research.
