Probook raises $40 million for AI tools aimed at home service firms

Probook has raised $40 million to build AI software for home service companies, Fortune reported. The funding puts fresh venture capital behind a startup trying to automate dispatch, scheduling and customer follow-up for plumbing, electrical and HVAC operators.

The New York company raised a $34 million Series A led by Andreessen Horowitz and a $6 million seed round led by Sequoia Capital, according to Fortune. Sequoia also took part in the Series A, Fortune reported.

Probook was co-founded by George Eliadis, Ben Cervantez and Lewis Zhang, according to Fortune. Eliadis, 24, spent six summers pressure washing houses in upstate New York with his father before earning a Wharton degree, Fortune reported.

Focus on dispatch

Probook is pitching itself as an AI operating system for home service businesses. Fortune reported that the company is targeting a sector that includes HVAC shops, plumbers and electrical contractors, and cited McKinsey work describing U.S. home services as a $700 billion industry.

Eliadis told Fortune that many home service operators bought separate AI products for voice calls, chat, follow-up and other tasks, only to end up with multiple vendors and rising costs. His argument, as reported by Fortune, is that those tools often miss dispatch, where companies assign technicians to jobs and set the order of work.

Probook began with scheduling and dispatch before adding tools for answering calls, cleaning job data and sending customer updates, according to Fortune. Eliadis described dispatch to Fortune as the central decision point for customer experience in a home service company.

Early customer results

Probook says one Indiana customer with 14 locations and 260 technicians used the platform to book 2,542 jobs in its first month without human involvement in the booking process, according to a company case study cited by Fortune.

Fortune also reported that a Florida operator reduced its dispatcher count from 22 to 10 after using Probook. A Kansas customer made the same dispatcher reduction and increased average job revenue by 20%, according to Fortune.

The company’s current sweet spot is private equity-backed home services rollups, Fortune reported. Those buyers have been acquiring local HVAC and plumbing businesses and combining them under larger operators, and Fortune cited Profitability Partners data showing the pace of such acquisitions grew 88% year over year through mid-2025.

ServiceTitan remains a key factor

Probook’s position is complicated by ServiceTitan, the publicly traded software company that Fortune described as the dominant platform for home service businesses. Morningstar lists ServiceTitan at a $6.3 billion market value, and Fortune reported that the company has $960 million in revenue and its own engineering team.

ServiceTitan already offers an AI scheduling product, according to Fortune. Probook is listed as a ServiceTitan partner, and Eliadis told Fortune the products are complementary.

David Haber, a general partner at Andreessen Horowitz, described Probook’s position in a written statement to Fortune as benefiting from a years-old structural moat. Sequoia partner Konstantine Buhler told Fortune that Eliadis’s background in the trades helped explain the firm’s investment, saying many founders building for the trades have not worked in them.

Eliadis was Probook’s only salesperson until February, Fortune reported. He has attended customers’ weddings and stayed on their couches, according to Fortune, as the company built relationships in a market where operators often value personal trust alongside software performance.
