Probook raises $40M to automate scheduling for plumbers and electricians

A startup founded by a Wharton graduate who spent summers pressure-washing homes has secured $40 million in venture funding to automate the daily operations of plumbing, electrical, and HVAC businesses.

George Eliadis, 24, built Probook after experiencing firsthand the inefficiencies that plague small home service companies. During six summers working with his father in upstate New York, he spent hours driving between jobs and frequently missed customer calls while on ladders. Those experiences informed his decision to create an AI platform that handles scheduling, dispatch, customer communication, and job management in a single system.

The company raised a $34 million Series A led by Andreessen Horowitz and a $6 million seed round led by Sequoia Capital, according to Fortune, which first reported the funding.

How the platform works

Probook operates as an end-to-end system that manages customer interactions without requiring multiple disconnected tools. When a customer calls about a broken water heater, the AI answers immediately and assigns the appropriate technician based on experience, location, availability, and historical performance metrics. The system then alerts the technician and sends updates to the customer.

Eliadis said existing AI tools in the home services sector have created problems rather than solved them because they operate in isolation. His platform aims to consolidate functions that previously required separate vendors and software packages.

Early customer results

One Indiana-based repair service with 14 locations and 260 technicians booked 2,873 jobs in its first month using Probook with no human involvement in the scheduling process, according to the company. A Kansas business using the platform for eight months reported a 10% increase in revenue per job while operating with a team 40% smaller than before.

Probook is also targeting private equity firms that acquire and consolidate home service businesses, positioning automation as a way to improve margins across portfolio companies.

Why it matters

Small trade businesses represent a massive but technologically underserved market. Inefficient scheduling and dispatch directly translate to lost revenue when technicians spend excessive time traveling or when calls go unanswered. By automating these core functions, platforms like Probook could help mom-and-pop operations compete more effectively while addressing persistent labor shortages in the skilled trades. The substantial venture backing also signals investor confidence that AI can successfully penetrate blue-collar industries that have historically resisted software adoption.

Competition ahead

Probook faces a significant competitor in ServiceTitan, a publicly traded company valued at $6.3 billion that operates in the same market. ServiceTitan has its own AI scheduling product, and Probook currently appears as a ServiceTitan partner, meaning the companies collaborate rather than directly compete for now.

Investors at Andreessen Horowitz and Sequoia believe Eliadis has an advantage because he worked in the trades before becoming a founder. Konstantine Buhler, a partner at Sequoia, noted that most founders building software for trade businesses have never actually worked in those fields.
