Probook raises USD $40 million for home services dispatch

Probook has raised USD $40 million from Andreessen Horowitz and Sequoia Capital, including a USD $34 million Series A and a USD $6 million seed round.

The New York-based software company focuses on dispatch operations for home services businesses such as plumbers, electricians, and HVAC providers. Andreessen Horowitz led the Series A, while Sequoia Capital led the seed round and also participated in the later financing.

Its product is built around dispatch rather than lead generation, which Probook argues many software providers serving the trades have overlooked. The platform combines customer intake, data cleaning, messaging, and outbound communication for service operators and field technicians.

The company is targeting a sector where scheduling and job assignment can shape response times, staff utilisation, and customer experience. In home services, dispatch teams often coordinate incoming leads, bookings, technician routes, and follow-up communication across multiple locations.

George Eliadis, Chief Executive Officer and Co-Founder of Probook, traced the company's origins to his own experience in the trades. He said he first encountered the operational problems Probook now aims to solve while working in a family pressure-washing business and later at an HVAC, plumbing, and electrical operator.

"I started Probook to solve a problem in my own business," said George Eliadis, Chief Executive Officer and Co-Founder of Probook.

He expanded on that background in a second comment. "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," Eliadis said.

Eliadis also described what he sees as a gap in the wider market. "Most AI vendors flocked to this space because it looked attractive on a spreadsheet," he said. "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."

Customer base

Probook now serves customers across hundreds of locations in the United States, from independently owned operators to private equity-backed groups. Named customers include TurnPoint Services, Master Trades Group, Del-Air, Peterman Brothers, and Sila Services.

Peterman Brothers uses the platform across 11 markets and 200 technicians, according to Probook. The company said the customer has centralised dispatch without adding overhead as it expands.

"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, Chief Executive Officer of Peterman Brothers.

Probook also cited Summers Plumbing, Heating & Cooling, which operates across 14 locations and 260 technicians on the platform. According to the company, that customer booked 2,542 jobs in its first month on Probook with no human intervention.

Del-Air also runs the software across multiple parts of its operation, according to Probook. The Florida business has eight locations.

"We chose Probook over other AI vendors because they know dispatch. They're also part of our front-line CSR," said Rick Rogers, Chief Executive Officer of Del-Air. "Dispatch is the nerve center of every home service business, and Probook built their entire platform around it."

Investor backing

The financing brings together two of Silicon Valley's best-known investment firms as software companies push deeper into operational workflows rather than standalone marketing and customer service tools. For Probook, the case to investors rests on the argument that dispatch sits at the centre of how home service operators manage jobs, staff, and customers.

David Haber of Andreessen Horowitz framed that positioning as the core of the investment case. "Dispatch is the nerve center of every home service business, and Probook built their entire platform around it. 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," he said.

Sequoia Capital, which first backed the company in its seed round, has also increased its support. The firm pointed to the founding team's industry experience as a differentiator in a market drawing growing attention from technology investors.

"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," said Konstantine Buhler, Partner at Sequoia Capital.

Expansion plans

Probook will use the new capital to grow its go-to-market team and add staff in engineering and customer success. It also deploys with customers in person and configures the system alongside front-line teams, reflecting the operational complexity of larger home services businesses with multiple branches and technician networks.

The funding gives Probook more room to expand in a fragmented market where operators are under pressure to improve booking speed, technician utilisation, and customer communication without increasing back-office headcount. Summers Plumbing, Heating & Cooling booked 2,542 jobs in its first month on Probook with zero human intervention.
