Mirendil says it raised $1B in a Series A

Mirendil's post, published 12 November 2026 at 9:00 am PT, says the company raised $1B in a Series A. It says the round was led by Kleiner Perkins and Clearlake Capital, with participation from Battery Ventures, Doerr Capital, Gil & Co, Google, M13, Pear VC and S32, among other new and existing investors. The post does not state a valuation.

The post says one researcher, working with agents, pretrained Mirendil-Base, which it calls a competitive coding model, from scratch in 3.5 months with less than $10M in compute. It says that model was then post-trained into Fern, which holds up to 10M tokens of context. It says Lor, now in private beta, uses hundreds of agents writing code and running experiments for days at a time, and that Mirendil runs on Lor every day. Those training and product lines are the company's account.

What it means for business: the figure on the post is a $1B Series A. The post does not state a valuation, a price for Lor or Fern, or a date for a general release. Lor is described as in private beta. This describes the announcement. It is not advice on the investment.
