NEW YORK, NY, June 24, 2026 – Probook raised $40 million to expand software built around dispatch operations for home services businesses. The financing includes a $34 million Series A led by Andreessen Horowitz and a $6 million Seed round led by Sequoia Capital.
The company’s platform connects lead intake, booking, customer messaging, data cleanup, technician assignment and outbound communication around the dispatch workflow. Probook built dispatch as the core function first, then added intake, data cleaning, messaging and outbound functions on a shared context layer.
The platform keeps each customer on one text thread and one phone number from initial contact through technician arrival. It answers inbound leads with information, cleans bookings before assignment, routes exceptions to human staff, and gives technicians opportunities to sell while helping shops run more jobs.
“I started Probook to solve a problem in my own business,” said George Eliadis, CEO and co-founder of Probook. “I grew up pressure washing in upstate New York with my dad. Six summers in the truck. I spent two to three hours of my day driving between jobs. I’d be up on a ladder washing a house and miss calls because I couldn’t hear my phone ringing.”
“Most AI vendors flocked to this space because it looked attractive on a spreadsheet,” he continued. “We came to it because we grew up in it. Dispatch is the hardest problem in home services. If you don’t start there, you can’t understand the business.”
Probook deploys with customers in person and configures the platform with front-line teams. The company serves customers like shops to private equity-backed platforms. Customers include TurnPoint Services, Master Trades Group, Del-Air, Peterman Brothers, and Sila Services.
“With Probook, we’ve centralized dispatch across 11 markets and 200 technicians without adding overhead. That scalability is critical to how we grow,” said Chad Peterman, CEO of Peterman Brothers.
Summers Plumbing, Heating & Cooling uses Probook across 14 locations and 260 technicians. The company booked 2,542 jobs in its first month on the platform with zero human intervention.
“Dispatch is the nerve center of every home service business, and Probook built their entire platform around it.” said David Haber, general partner at Andreessen Horowitz. “It’s a years-old structural moat. America’s largest home service brands run on Probook today. We’re proud to have led their Series A.”
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.”
