TL;DR: Probook has raised $40 million — a $34 million Series A led by Andreessen Horowitz and a $6 million seed round led by Sequoia Capital — to build an AI operating system that automates dispatch, scheduling, and customer communications for plumbers, electricians, and HVAC operators. One customer booked more than 2,500 jobs in a single month without any human intervention, and some operators have achieved technician-to-dispatcher ratios as high as 100:1. AI dispatch for home service businesses has moved from concept to funded infrastructure.

Probook, an AI operating system purpose-built for home service businesses, closed $40 million in funding this week — a $34 million Series A led by Andreessen Horowitz and a $6 million seed round originally led by Sequoia Capital, which returned to co-invest in the Series A. The raise arrives as plumbers, HVAC technicians, and electricians are adopting AI automation tools at an accelerating pace, and as dispatch — the operational nerve center of every field service business — has emerged as the most visible bottleneck to growth.
Founder George Eliadis came to the problem with direct credibility. He ran a pressure-washing business before earning his MBA at Wharton, where the operational pain of field service work shaped the company’s design philosophy. Probook was not built as a general-purpose service platform with dispatch tacked on — it was architected dispatch-first, then expanded outward into intake, customer messaging, outbound communication, and data verification. The new capital will fund growth across engineering, customer success, and go-to-market as demand scales across the sector.
The platform currently serves businesses ranging from independent owner-operators to private-equity-backed service platforms. Per company-reported data, one customer booked more than 2,500 jobs in a single month without human intervention. According to Probook, some operators have achieved technician-to-dispatcher ratios as high as 100:1 — a level of operational leverage that traditional home service staffing models, where one dispatcher typically handles four to six field technicians, cannot approach.
Why AI Dispatch for Home Service Businesses Is Drawing Institutional Capital
The competitive context makes the thesis clear. ServiceTitan, the dominant player in the field service software market with a multi-billion-dollar valuation, built an end-to-end operating system for contractors where dispatch is one capability among many. Jobber and Housecall Pro have each raised significant capital to simplify scheduling, payments, and customer management for smaller operators. Probook’s differentiated claim is that none of these platforms treated dispatch as the primary intelligence layer — and that AI dispatch for home service businesses is where the next wave of operational transformation will concentrate. The backing of both Andreessen Horowitz and Sequoia Capital in the same company reflects institutional conviction that this thesis is correct. For small business owners managing lean field teams without dedicated operations staff, platforms like Probook signal the same consolidation shift driving every service vertical right now: replacing fragmented, labor-intensive coordination with AI systems that book, route, and communicate without human intervention.
