Jacob Lagerros

Jacob Lagerros is the founder of Ulyssean, a company building integrated hardware and software systems to secure the infrastructure that trains and runs frontier AI models, with backing from leaders at Anthropic, DeepMind, Meta, and CrowdStrike. Originally from Stockholm, Sweden, he studied at the University of Oxford and partially completed an MSc in Economics and Finance at LSE before dropping out to work full-time on AI safety-related projects. He co-founded Lightcone Infrastructure, the parent organization of LessWrong, where he worked on the Campus team alongside Oliver Habryka and others. Earlier in his career, he co-directed EAGxOxford 2016, served as secretary of the Oxford Prioritisation Project, and received a Long-Term Future Fund grant in 2019 to build forecasting infrastructure giving x-risk researchers superforecasting ability with minimal overhead, collaborating with Metaculus and Ozzie Gooen on that project. He has since pivoted toward AI hardware security, co-leading the UK Secure Cluster, advising government bodies including the National Security Council on AI export controls, and presenting at the Paris AI Security Forum 2025. He is also a mentor at Pivotal Research in the area of AI hardware security.
