Probook Raises $40M in Seed and Series A Financing

The funding round included a $34 million Series A led by Andreessen Horowitz (a16z) and a $6 million seed round led by Sequoia Capital, which also participated in the Series A round.

The company plans to use the funding to expand its go-to-market efforts to meet rising demand, strengthen its software engineering team, and grow its customer success organization to support large-scale national deployments.

Probook was built starting with dispatch, and then expanded into intake, data cleaning, customer messaging, and outbound workflows. This was made possible because all functions run on a single shared context layer.

Each customer stays on one continuous text thread with one phone number from the first contact through to service completion. Every inbound lead receives accurate information, every booking is cleaned before being assigned, and humans only handle exceptions. As a result, technicians complete more sales, shops handle more jobs, and operators improve EBITDA while delivering a fully connected customer experience for the first time.

Probook works directly with customers on-site, setting up the platform alongside their front-line teams and staying accountable for the results it delivers.

The company supports customers across hundreds of locations in the U.S., including both independent businesses and private equity-backed platforms. Its customers include TurnPoint Services, Master Trades Group, Del-Air, Peterman Brothers, and Sila Services.

“Dispatch is the nerve center of every home service business, and Probook built their entire platform around it. "said David Haber, General Partner at Andreesen 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."

"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.

"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."

“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.”
