The AI operating system for home services - built around the one decision every HVAC, plumbing and electrical shop makes thousands of times a day: which technician goes where.
NEW YORK - George Eliadis learned the trades from a ladder, running a pressure washer loud enough to drown out a ringing phone. The company he built with Lewis Zhang and Ben Cervantez now answers those calls, and reshuffles the dispatch board, with AI. Photographed in the world it was built for: the American service van, mid-route, between jobs.
Probook is a New York startup selling artificial intelligence to an industry that software mostly forgot. Its customers are home services contractors - the HVAC, plumbing and electrical companies that send technicians to houses - and its product sits on the part of the business that decides everything: dispatch.
Every service shop runs a dispatch board, a live grid of technicians and jobs. Deciding who goes where, and in what order, sets the day's revenue. Historically a dispatcher makes those calls by hand, juggling drive times, skill sets, and which tech tends to close a sale. Probook's software watches that board and re-optimizes it in real time, matching the right technician to each job by expertise and context.
The company offers two modes. In copilot, Probook recommends moves while keeping the human dispatcher in charge. In autopilot, it reshuffles the board itself, which the company says lets a single dispatcher manage more than twenty technicians. On average, Probook reports customers see roughly a 12% increase in sales and a 19% rise in flip rates.
What separates the pitch from the crowd of AI startups is who is making it. CEO George Eliadis spent six summers pressure washing houses across six upstate New York counties with his father, driving two to three hours a day between calls. "Competitors flocked to this space because it looked attractive on a spreadsheet," he has said. "We came to it because we grew up in it."
In June 2026 the company disclosed $40 million in funding: a $34 million Series A led by Andreessen Horowitz and a previously undisclosed $6 million seed led by Sequoia Capital. Both firms are backing a simple thesis - that dispatch is the nerve center of a roughly $700 billion industry, and whoever automates it well has a durable position.

Figures are company-reported averages across customers. Individual results vary.
Copilot and autopilot modes match techs to jobs by expertise and context, re-optimizing the board live so one dispatcher can run 20+ techs.
A dispatcher-friendly interface that layers on top of the ServiceTitan board - no rip-and-replace.
Handles inbound voice calls and web leads with full context, automating a large share of customer chats.
Fills schedules, revives unsold estimates, and runs background and history checks before assignment.
Real-time ETA and revenue predictions plus technician performance metrics.
Probook sells B2B software to home services contractors. Rather than asking a shop to abandon its core field-service platform, it layers on top of tools like ServiceTitan, positioning itself as an operating system that unifies intake, dispatch, customer messaging and outbound. Deployment is deliberately hands-on: the team installs and tunes the system in person and holds itself accountable for measurable outcomes.
The market is large and, until recently, lightly served by modern software. The US home services sector is estimated at roughly $700 billion a year. Competitors range from field-service suites like ServiceTitan's native dispatch, Housecall Pro and Workiz to a new wave of AI scheduling startups. Probook's wedge is depth over breadth - owning the dispatch decision inside the systems operators already trust, then expanding outward from there. Investors describe that focus as a structural moat: dispatch is where a service business either makes or loses its day.

$40 million in total: a $6 million seed led by Sequoia Capital and a $34 million Series A led by Andreessen Horowitz, announced in June 2026.
No. Probook is a ServiceTitan partner and overlays the ServiceTitan dispatch board, so operators keep using the software they already run while adding AI dispatch on top.
