Probook raises $40M ($34M Series A, a16z lead) for AI dispatch OS targeting $700B home services
Probook raised $40 million in total funding including a $34 million Series A led by Andreessen Horowitz and a $6 million seed led by Sequoia Capital, which also participated in the Series A. The company is building an AI operating system for home service businesses—HVAC shops, plumbing outfits, and electrical contractors that collectively power a $700 billion industry.
Early results show an Indiana customer with 14 locations and 260 technicians booked 2,542 jobs in its first month without a single human touching the booking. A Florida operator cut its dispatchers from 22 to 10. A Kansas shop did the same and grew its average job revenue by 20%. These outcomes reflect founder George Eliadis's deep experience: he spent six summers pressure washing with his dad and later worked inside a major HVAC/plumbing/electrical operator before founding Probook.
Unlike point-solution voice agents and chatbots that address lead generation, Probook unified dispatch, intake, scheduling, communications, and follow-up around a shared customer-context layer. The company deploys with customers in person and maintains accountability for operational outcomes, not just software adoption.
For practitioners in operational automation and vertical SaaS: Probook's funding validates that dispatch is the leverage point for home services AI. The $700 billion market fragmentation plus 88% YoY PE consolidation (through mid-2025) creates scale opportunities for platforms that reduce human coordinators while increasing technician utilization and revenue per job. Dispatch-first architecture, vertical expertise, and outcome accountability are becoming the differentiators versus generalist AI platforms.
