Probook, a vertical AI solution for home services, has secured $34 million in Series A funding led by Andreessen Horowitz (a16z). This round brings the company's total capital raised to $40 million, following a seed round led by Sequoia.

The investment underscores a shift in vertical AI, moving beyond superficial customer engagement tools. Probook targets the core operational challenge in home services: technician dispatch.

Reframing Home Services AI

For years, AI development in home services largely concentrated on peripheral functions like voice agents and chat widgets. These solutions, while visible, often failed to address the fundamental decisions that drive profitability.

Probook's strategy prioritizes owning the most complex and central decision: dispatch. This involves intelligently assigning the right technician to the right job, considering skills, conversion rates, and expertise, rather than simply proximity.

The company built its platform around this core function, then expanded to encompass other front-office operations. These include intake, data scrubbing, customer messaging, and outbound communications.

An integrated context layer ensures seamless information flow across the system. This allows for a unified customer experience, with all interactions managed through a single text thread.

Automated processes handle routine tasks, freeing human operators to manage exceptions. This approach directly contributes to increased EBITDA for businesses utilizing Probook.

Industry Roots and Impact

CEO George Eliadis, who grew up in the home services industry, co-founded Probook with CTO Lewis Zhang and Ben Cervantez. Their deep domain empathy, combined with technical expertise, shaped the platform's development.

Probook deploys its platform directly with customers, configuring it alongside front-line teams and committing to measurable outcomes. This hands-on approach has fostered trust in a category often characterized by detached software vendors.

The platform is already deployed across hundreds of locations nationwide. These range from independent shops to private-equity-backed platforms like TurnPoint Services and Sila Services.

Summers Plumbing, Heating & Cooling, with 14 locations, booked 2,542 jobs in its first month on Probook with zero human intervention. Del-Air reported a doubling of dispatcher productivity, from 10 to 22 technicians per dispatcher.
