Probook, the AI Operating System for home service businesses, today announced $40 million in funding. The investment comprises a $34 million Series A led by Andreessen Horowitz (a16z) and a $6 million Seed round led by Sequoia Capital. Sequoia also participated in the Series A.
Home service operators spent the last three years buying AI. A voice agent. A chat widget. A follow-up tool. Each one owned a slice of the customer, and none of them talked to each other. Every vendor built for the top of the funnel, where leads come in — and ignored dispatch, the brain of every home service business, where customer experience is made or broken. Operators ended up with a stack of point solutions and a piecemeal customer experience.
Probook built dispatch first. Intake, data cleaning, customer messaging, and outbound came next, only possible because everything shares one context layer. Every customer stays on one text thread, with one number, from the first touch through the front door. Every inbound lead is answered with perfect information. Every booking is cleaned before assignment. Humans manage exceptions. Techs sell more. Shops run more jobs. Operators add points to their EBITDA and, for the first time, run a connected customer experience.
George Eliadis spent a summer inside TR Miller, a $40M HVAC, plumbing, and electrical shop in Illinois that became Probook’s first customer. There, he saw the same problems at scale.
Probook deploys with customers in person, configures the platform alongside their front-line teams, and stays on the hook for the outcomes it sells.
Probook serves customers across hundreds of locations nationwide, from independently owned shops to private equity-backed platforms. Notable customers include TurnPoint Services, Master Trades Group, Del-Air, Peterman Brothers, and Sila Services.
Summers Plumbing, Heating & Cooling, with 14 locations and 260 technicians on the platform, booked 2,542 jobs in its first month on Probook with zero human intervention.
Del-Air, an 8-location operation in Florida, runs Probook across the stack. “We chose Probook
over other AI vendors because they know dispatch. They’re also part of our front-line CSR,” noted Rick Rogers, CEO.
Konstantine Buhler, Partner at Sequoia Capital, added: “Most founders building for the trades have never worked in them. George has. Pair that with the team’s outlier technical depth, and you see why we backed Probook at Seed and why we’re doubling down now.”
Probook will use the capital to scale its go-to-market team against surging demand, and grow engineering and customer success to deliver on it.
