Today, I’m excited to formally announce @MirendilAI 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! @HarshMeh1a, @shayan_, @tararezaeikh

Announcing $40M in funding from @sequoia and @a16z. I grew up pressure washing houses in upstate New York. Six summers in the truck, missing calls from the top of a ladder because I couldn't hear my phone ring. My co-founder Ben grew up plumbing with his dad in San Francisco. We entered home services because we grew up in it. I spent a summer inside TR Miller, one of the best-run HVAC, plumbing and electrical shops in the country, and their workflows were still raw. The first wave of AI in the trades was point solutions. One tool for voice, one for outbound, one for follow-up. Operators ended up with five vendors and more overhead. Probook is the AI operating system that helps you add points to your EBITDA and run your entire customer experience as one connected system, built around dispatch. Many of America’s largest home service brands run on Probook today. Summers Plumbing booked 2,542 jobs their first month with us, zero human intervention. Anthony PHCE ran 20% more revenue per job on a 50% leaner team. Del-Air more than doubled productivity from 10 to 22 techs per dispatcher. To everyone who trusted us early: thank you. Back to work. We're hiring.
