Mirendil raises $1B Series A led by Kleiner Perkins to democratize AI R&D

Mirendil announced a $1B Series A led by Kleiner Perkins and Clearlake Capital, with participation from Battery Ventures, Google, M13, Pear VC and others, to build tools that make frontier AI R&D accessible to scientists and engineers. The company says one researcher working with agents pretrained Mirendil-Base, a competitive coding model, from scratch in 3.5 months with less than $10M in compute, then post-trained it into Fern, which holds up to 10M tokens of context. Lor, now in private beta, lets hundreds of agents write code and run experiments for days at a time, and Mirendil says it runs on Lor every day.
