Behnam Neyshabur and Harsh Mehta left Anthropic December 2025 after joining late 2024. Raised 1B for Mirendil — one of largest AI seed rounds. a16z and Kleiner Perkins led; NVIDIA participated.
Mirendil trains specialized models on frontier AI research tasks: experimental design, hyperparameter search, model evaluation, iterative training. University biology labs could build drug-target models without dedicated ML engineering teams.
Argument: frontier AI research should not be confined to handful of tech companies. GPU-controlled autonomous iteration platform for organizations outside major labs.
