YC F26 · halmoslabs.com
Halmos Labs — Software that picks the most informative lab experiments
Halmos Labs builds autonomous systems for scientific research: intelligent experimental design software that works out which experiment would reduce uncertainty most, so labs get more information from fewer experiments and fewer experiments per conclusion. The platform runs parallel analyses under many possible assumptions, validates every analysis, and answers open-ended questions about results where fixed workflows fall short, with early work spanning wet-lab experiment design and cancer vaccine manufacturing. Founded in 2026 in Lund, Sweden by Mattias Akke and Linus von Ekensteen Lofgren, who have worked at MIT, AstraZeneca and Danske Bank. Part of Y Combinator's Fall 2026 batch.
