About Ressl AI
Summary
Ressl AI builds autonomous back-office agents for trades businesses, including HVAC, plumbing, electrical, roofing, and collision repair shops. The agents handle quoting, estimating, parts procurement, insurance coordination, scheduling, and customer follow-ups by working across the software these businesses already run, replacing the "glue" employees whose jobs consist of copy-pasting between tools and routing work between systems. Each agent takes ownership of a task end-to-end, from reading the incoming request to completing the update and passing context forward, so field crews and shop operators do not have to.
Business model
Book a demo sales motion; pricing structure not public.
Go-to-market
Ressl sells directly to shop operators and through PE-backed roll-up platforms looking to improve margins across portfolio companies in the trades and field services sector.

AI Workers for Field Services
We automate the back office so field crews can focus on the actual work. Trades businesses (HVAC, plumbing, electrical, collision repair, roofing) run on legacy software and "glue" employees: people whose entire job is clicking through systems, copy-pasting between tools, and managing inbound volume across channels. A collision shop has one person generating estimates in CCCOne, another chasing parts vendors, another answering calls and Yelp messages, another doing invoices in QuickBooks. None of that requires a human. We build proactive background agents that run these operations autonomously -- quoting, estimating, procurement, insurance coordination, scheduling, follow-ups -- on top of the software these businesses already own. We started as an AI consulting firm talking to businesses across every industry. After a month, the pattern was obvious - trades and field services had the most "glue work" and the least tech sophistication to solve it themselves. Every shop we walked into had 2–4 people doing work that software should be delivering as an outcome, not just enabling. Our GTM is direct to operators and through PE-backed roll-ups, who are actively looking for margin improvements across their portfolio companies.
