Probook, a New York City-based startup building artificial intelligence software for home service contractors, has raised $40 million in combined funding to expand its AI-driven dispatch platform for HVAC, plumbing and electrical businesses. The company disclosed a $34 million Series A led by Andreessen Horowitz, along with a previously undisclosed $6 million seed round led by Sequoia Capital, which also participated in the new round, according to an exclusive report published by Fortune on June 23.
Founder and chief executive George Eliadis, a 24-year-old Wharton graduate who spent six summers pressure washing houses in upstate New York with his father, said Probook was built around a specific insight: dispatch, not customer-facing chatbots or voice agents, is what actually determines whether a home service business runs profitably. "Dispatch is the brain of every home service business," Eliadis told Fortune. "That's where customer experience is made or broken."
Probook's AI Handles Dispatch First, Then Everything Else
Rather than launching with a general-purpose AI assistant, Probook said it built its scheduling and dispatch engine first, then layered on supporting features including automated call answering, job data cleanup and customer status updates within the same connected system. The company said the approach responds to a complaint it heard repeatedly from contractor customers, who described accumulating separate AI vendors, including voice agents, chat widgets and follow-up bots, without any single tool built specifically to handle the core task of assigning technicians to jobs in the right order.
Probook cited early results from several customers to support that approach. An Indiana-based contractor with 14 locations and 260 technicians booked more than 2,500 jobs in a single month without a human involved in the booking process, according to the company. A Florida operator reduced its dispatcher headcount from 22 to 10, and a Kansas contractor made a similar staffing reduction while growing average job revenue by 20%, Probook said.
Probook Aims at Private Equity-Backed HVAC Rollups
Probook said its highest-value customer segment is the private equity-backed home services rollup, referring to investment firms that have been acquiring local HVAC and plumbing shops and consolidating them under shared platforms to cut costs and standardize operations. That consolidation trend has accelerated industrywide, with acquisition activity among home services platforms growing 88% year-over-year through mid-2025, according to data cited in the Fortune report. Probook markets its software directly to the owners and operators of those platforms, who the company said are focused on improving margins across newly combined businesses.
The home services software market Probook is entering is dominated by ServiceTitan, a publicly traded company valued near $6.3 billion with roughly $960 million in annual revenue. ServiceTitan has its own AI scheduling product, and Probook is currently listed as a partner on ServiceTitan's marketplace rather than positioning itself as a direct competitor. Andreessen Horowitz general partner David Haber, in a written statement, called the dynamic between the two companies "a years-old structural moat." Eliadis has described Probook's relationship with ServiceTitan as complementary, though Fortune noted the incumbent's scale and in-house engineering team as a factor Probook will have to keep navigating.
Sequoia Capital partner Konstantine Buhler, who backed Probook's seed round in early 2025 before doubling down on the Series A, said Eliadis's background working directly in the trades set the company apart from other startups pitching software to contractors. "Most founders building for the trades have never worked in them," Buhler said. "George has." Eliadis served as Probook's only salesperson until February of this year, according to the Fortune report, and has attended customers' weddings and slept on their couches while building relationships across the industry.
The home services industry Probook is targeting, spanning HVAC, plumbing and electrical contracting, represents roughly $700 billion in annual economic activity in the United States, according to McKinsey research cited alongside the funding announcement. Probook's pitch centers on consolidating the fragmented point solutions many contractors have adopted piecemeal in recent years, replacing separate booking, communication and follow-up tools with a single connected system anchored by dispatch.
Eliadis founded Probook alongside co-founders Ben Cervantez and Lewis Zhang, according to Fortune. The company has not disclosed the size of its engineering or customer-success teams, though it said the new funding will go toward expanding its engineering headcount and broadening the range of home service functions its AI system handles beyond dispatch, call answering and customer communications.
Probook did not disclose a valuation associated with the new funding or specify how many contractor customers currently use its platform. Fortune reported the deal as part of its Term Sheet newsletter coverage of venture financings on June 23, alongside separate funding rounds for companies in crypto analytics, AI voice agents and enterprise software.
