Probook raises $40M across a $34M Series A led by Andreessen Horowitz and a $6M Seed round led by Sequoia Capital<\/p>\n
The startup is building an AI operating system for home service businesses, automating dispatch, scheduling, and customer communications<\/p>\n
Customers report significant efficiency gains, with some achieving technician-to-dispatcher ratios as high as 100:1<\/p>\n
Built by a founder who spent six summers pressure washing houses with his father, Probook<\/a> is taking on one of the most overlooked problems in home services: dispatch.<\/p>\n George Eliadis<\/a> grew up working in the trades in upstate New York, often spending hours driving between jobs and missing customer calls while on-site. Years later, after working inside a $40 million HVAC, plumbing, and electrical business, he realised the same operational bottlenecks existed at scale. While dozens of startups were building AI tools for lead generation and customer acquisition, few were tackling the operational nerve centre that determines whether a home service business succeeds or fails.<\/p>\n That insight has now attracted some of Silicon Valley\u2019s biggest investors.<\/p>\n Probook, the AI operating system for home service businesses, has raised $40 million in funding, including a $34 million Series A led by Andreessen Horowitz<\/a> (a16z) and Sequoia Capital<\/a>, which led it\u2019s\u00a0 $6 million seed round.<\/p>\n The company is building software that automates dispatch, customer communication, data verification, and scheduling for home service providers across plumbing, HVAC, electrical, and maintenance sectors. Customers have reported significantly faster response times and improved operational efficiency, with some achieving technician-to-dispatcher ratios as high as 100:1.<\/p>\n The new capital will be used to expand Probook\u2019s engineering, customer success, and go-to-market teams as demand continues to grow across the sector.<\/p>\n Why dispatch remains the industry\u2019s biggest bottleneck<\/p>\n Home services is a massive industry, yet many businesses still rely on manual dispatch operations to coordinate technicians, manage bookings, and communicate with customers.<\/p>\n Over the past few years, operators have adopted a growing number of AI tools. However, most have been built around lead generation and customer acquisition rather than operational execution.<\/p>\n The result has been a patchwork of disconnected systems that create friction for both customers and employees.<\/p>\n Probook believes dispatch is the operational brain of every home service business. Rather than treating it as another workflow, the company built its entire platform around dispatch first before expanding into intake, customer messaging, outbound communication, and data cleaning.<\/p>\n Because all functions operate from a shared context layer, every customer interaction remains connected from the first enquiry through job completion. The company says this enables faster response times, higher technician utilisation, and a more seamless customer experience.<\/p>\n Built by people who worked in the trades<\/p>\n Unlike many startups entering the sector, Probook\u2019s founders have direct experience working in home services. Eliadis was joined by Lewis Z<\/a>, and Ben Cervantez<\/a> in 2024 in New York.\u00a0<\/p>\n \u201cI started Probook to solve a problem in my own business,\u201d said George Eliadis. \u201cI grew up pressure washing with my dad and spent hours every day driving between jobs and missing customer calls.\u201d<\/p>\n His understanding of the industry deepened after working inside TR Miller, which later became Probook\u2019s first customer.<\/p>\n \u201cMost AI vendors came into the industry because it looked attractive on paper,\u201d he said. \u201cWe came to it because we grew up in it. Dispatch is the hardest problem in home services.\u201d<\/p>\n That industry-first perspective has become a key part of the company\u2019s strategy. Probook deploys alongside customers in person, works directly with front-line teams, and remains closely involved in implementation rather than simply selling software.<\/p>\n Customers are already seeing measurable results<\/p>\n The platform is now used across hundreds of locations nationwide, serving businesses ranging from independent operators to private-equity-backed service platforms.<\/p>\n Customers include TurnPoint Services, Master Trades Group, Del-Air, Peterman Brothers, and Sila Services.<\/p>\n Peterman Brothers has centralised dispatch operations across 11 markets and 180 technicians using Probook.<\/p>\n \u201cWith Probook, we\u2019ve centralised dispatch across 11 markets and 180 technicians without adding overhead,\u201d said Chad Peterman<\/a>, CEO of Peterman Brothers.<\/p>\n Meanwhile, Summers Plumbing, Heating & Cooling booked 2,542 jobs during its first month on the platform with zero human intervention.<\/p>\n Some operators have reported technician-to-dispatcher ratios reaching 100:1, a level of efficiency rarely seen in traditional home service operations.<\/p>\n Why a16z and Sequoia are doubling down<\/p>\n The home services sector has become an increasingly attractive market for technology investors, driven by labour shortages, operational inefficiencies, and growing customer expectations.<\/p>\n Probook\u2019s investors believe the company has identified the industry\u2019s most important workflow.<\/p>\n \u201cDispatch is the nerve center of every home service business,\u201d said David Haber<\/a>, General Partner at Andreessen Horowitz. \u201cAmerica\u2019s largest home service brands run on Probook today.\u201d<\/p>\n Sequoia, which first backed the company at Seed stage, participated again in the Series A.<\/p>\n
