a16z Leads Seed Round for Mirendil
Andreessen Horowitz (a16z) announced it is leading the seed financing for Mirendil, a startup building a lab-grade, agentic research platform that trains frontier models specialized for AI R&D. Mirendil’s system is designed to let engineers — and eventually less-technical domain experts — run experiments, update model weights, and iterate on research workflows autonomously (including code execution and compute management). The a16z note highlights the team’s experience (Behnam Neyshabur, Harsh Mehta, Shayan Salehian, Tara Rezaei), contrasts Mirendil’s mission with closed internal platforms at major labs, and positions the company as enabling broader, externally accessible frontier AI work.
Seed funding for a company building an independent lab-grade platform to let external engineers and domain experts run frontier AI research could accelerate distributed model development and broaden who can perform pretraining and model iteration — relevant to the wider AI ecosystem and downstream tech industries.

Mirendil Signs $100M+ Google Cloud Compute Deal
AI startup Mirendil has entered a multi-year partnership with Google Cloud worth more than $100 million to secure compute capacity for its work on self-improving (recursive) AI. The agreement gives Mirendil access to Google TPUs, Nvidia GPUs and managed training clusters to support research aimed at AI systems that iteratively improve themselves and automate scientific research in fields like medicine and materials science. Mirendil’s co-founder and CEO Benham Neyshabur said the compute commitment is roughly half of the startup’s recent seed raise at a $1 billion valuation. Google framed the deal as part of its strategy to offer flexible orchestration across different accelerator types, while Mirendil says its systems layer will help customers get more out of Google’s hardware.
a16z Leads Armadin Series B
Andreessen Horowitz (a16z) announced it is leading Armadin's Series B funding round. Armadin, founded by former Mandiant and Google security veterans including Kevin Mandia, Travis Lanham, Evan Peña, and David Slater, offers an AI autonomous security platform designed to continuously pressure-test enterprise attack surfaces. The funding comes amid growing concerns about AI models being used in cyberattacks, as highlighted by recent incidents involving OpenAI, Anthropic, and Meta. Armadin's platform, currently featuring Armadin Red, provides agentic attack simulation, validated kill chains, and proactive remediation. The article emphasizes the need for continuous security testing rather than periodic pentests, positioning Armadin as a response to the evolving threat landscape.
