NOSO LABS

NOSO Labs is the first AI-powered sales enablement platform for the HVAC and plumbing industry. We help field technicians close more sales by automating proposal generation, streamlining note-taking and summaries, and – most importantly – following up with homeowners who don’t buy on the spot. In other words, every service call becomes a second chance to sell, with no opportunities left “falling through the cracks.”

Our AI assistant works alongside techs to ensure no money is left on the table. It generates polished, on-the-spot proposals and detailed visit summaries, then sends timely, personalized follow-ups that turn “maybe” into yes. The result? Higher close rates and revenue for our clients. In a recent case study, an HVAC contractor saw a double-digit jump in sales (10%+) within a few weeks of using NOSO’s AI follow-up tool.

Technicians stay focused on service, while our AI handles the sales hustle in the background. Backed by Y Combinator (Summer ’25), NOSO Labs is led by experienced founders on a mission to boost growth for HVAC and plumbing businesses. We’ve built the first AI sales assistant for home services, combining deep industry insight with cutting-edge AI. If you’re an HVAC/plumbing operator looking to increase revenue (or an investor tracking the next wave of Vertical SaaS), let’s connect – we’re proving that better tech in the trades means better business for all.
