The 24 year-old spent six summers pressure washing houses in upstate New York with his dad. Now he has a Wharton degree, and just raised $40 million from two of the most competitive names in venture capital to fix blue-collar and home services problems at scale.
Probook, his New York-based startup, raised a $34 million Series A led by Andreessen Horowitz and a $6 million seed led by Sequoia Capital, which also participated in the A, Fortune learned exclusively. The company is building what Eliadis calls an AI operating system for home service businesses—the HVAC shops, plumbing outfits, and electrical contractors that collectively power a $700 billion industry.
The pitch starts with a grievance. Over the last few years, home service operators were sold an explosion of AI tools—voice agents, chat widgets, follow-up bots. They ended up with five vendors and bills growing faster than the revenue those tools promised. According to Eliadis, none of these products were built for dispatch—the part of the business where an operator decides which of 40 technicians goes to which of 150 jobs, in what order, with what expected ticket size.
“Dispatch is the brain of every home service business,” he told Fortune. “That’s where customer experience is made or broken.”
So Probook built the scheduling brain first, then layered on everything else—answering calls, cleaning up job data, sending customer updates—in one connected system. The early numbers are promising: an Indiana customer with 14 locations and 260 technicians booked 2,542 jobs in its first month without a single human touching the booking. A Florida operator cut its dispatchers from 22 to 10. A Kansas shop did the same and grew its average job revenue by 20%.
Probook’s sweetest customer right now is the private equity-backed home services rollup—think investment firms that have been quietly buying up local HVAC and plumbing shops across the country, bundling them under one roof, and squeezing out efficiencies. That acquisition pace hit 88% growth year-over-year through mid-2025. And Probook sells directly to owners who are laser-focused on profit margins.
The harder question is what happens with ServiceTitan. The $6.3 billion publicly traded company is the dominant software platform for home service businesses—and it already has its own AI scheduling product. For now, Probook is listed as a ServiceTitan partner, meaning the two technically work together rather than against each other. Eliadis calls them complementary. A16z GP David Haber called it “a years-old structural moat,” in a written statement. Still, ServiceTitan has $960 million in revenue and its own engineers.
Eliadis was the company’s only salesperson until February of this year. He’s been to customers’ weddings. He’s slept on their couches. That founder obsession is exactly what Sequoia’s Konstantine Buhler cited when he backed the seed in early 2025 and doubled down on the A: “Most founders building for the trades have never worked in them. George has.”
See you tomorrow,
