Andreessen Horowitz (a16z) and Kleiner Perkins led a $200M seed round for…

Brief

Mirendil raised a $200M seed led by a16z and Kleiner Perkins (announced 2026-06-24) with major NVIDIA backing to build a self-accelerating AI R&D platform. Founded by Behnam Neyshabur, Harsh Mehta, Shayan Salehian, and Tara Rezaei, the ~20-person team from Anthropic, xAI, DeepMind and OpenAI aims to automate research loops and decentralize frontier AI capabilities.

Why it matters

Andreessen Horowitz (a16z) and Kleiner Perkins led a $200M seed round for Mirendil, announced 2026-06-24; NVIDIA made a major follow-on investment.

Key details

  • Mirendil is building an autonomous, self-accelerating AI R&D system — described as a coding agent that loops over research and engineering problems and controls its own GPUs to make progress without human intervention.
  • Founders Behnam Neyshabur, Harsh Mehta, Shayan Salehian, and Tara Rezaei head a ~20-person team of researchers/engineers recruited from Anthropic, xAI, Google DeepMind, and OpenAI, aiming to democratize frontier AI infrastructure for businesses and labs.
Source evidence

We're thrilled to lead Mirendil's $200M seed round.

Frontier AI work has been locked inside a few big labs.

@mirendil is building a system that can help anyone do AI work: they train frontier models that are expert at AI R&D and build the product around it. The result is a system that loops over research and engineering problems on its own, making progress without human intervention.

It's like a coding agent built for AI research that controls its own GPUs.

Mirendil is one of the few teams with the experience and the priors to make the end-to-end system work. @bneyshabur, @HarshMeh1a, @shayan_, and @tararezaeikh come out of Anthropic, Google DeepMind, and xAI.

Welcome to the a16z family, Mirendil.

Today, I’m excited to formally announce @mirendil with my amazing co-founders Harsh Mehta, Shayan Salehian, and Tara Rezaei!

We’re fortunate to work with @a16z and @kleinerperkins, who led our seed round of $200M, followed by a major investment from NVIDIA, among others.

Mirendil exists to accelerate science and technology, and through them, to help solve humanity's most pressing problems.

Self-accelerating AI R&D is the most direct path to delivering on AI's broader promise, which is why we believe the most important application of AI is AI itself. Get this loop right, and it compounds. It fundamentally changes the rate of progress itself across all domains.

We believe this capability should be democratized. It should be used to power all scientific efforts trying to innovate at the frontier. There are far more important problems—and broader ones—than any single lab can take on, so more groups should be able to pursue them.

This pulls concentration of power away from a few labs: businesses and science labs can own their AI and infrastructure, keep their margins, and control their own destiny instead of ceding it all to a single AI lab.

We’re a small team with a singular focus. Our founding team consists of 20 researchers and engineers from frontier institutions including Anthropic, xAI, Google DeepMind, and OpenAI, united by a passion for science and a drive to build the technologies that move it faster. If you want to build the system that builds systems, join us!
