Phil Krinner

Phil Krinner is the co-founder and CEO of Arch, a San Francisco company building AI revenue software for home services contractors, starting with HVAC and heat pumps. A Stanford GSB graduate and former McKinsey strategy consultant who once built large-scale solar plants and installed panels himself, Krinner started Arch after asking 15 contractors to quote a heat pump for his apartment and finding that not one could tell him whether it would save money. Arch uses public home data and AI to help contractors find the right homes, size systems in minutes, and run hyper-personalized campaigns. The company raised a $6.2M seed round in 2024 led by Coatue with Floodgate, Gigascale, ReGen and MCJ.
