Probook funding, valuation and investors

Overview

Probook is an AI operating system for home-services companies — automating dispatch, customer intake, data scrubbing, scheduling, and outbound messaging for HVAC, plumbing, electrical, and related trades. Founder George Eliadis (CEO), Ben Cervantez, and Lewis Z. built the platform around dispatch as the central decision layer rather than bolting AI onto generic CRM modules. Sequoia led a $6M seed and Andreessen Horowitz led a $34M Series A in June 2026, with Sequoia participating in both — $40M total. Press cites customers including Del-Air, Peterman Brothers, and Sila Services, with some operators reporting technician-to-dispatcher ratios as high as 100:1.

Why Probook is interesting

George Eliadis grew up in the trades and built dispatch-first AI that large HVAC/plumbing brands run today — rare a16z and Sequoia co-backing on a vertical where incumbents own the workflow.

Competitive landscape

Edge: Trades-native dispatch logic from founders who worked in the industry — Probook owns the hardest central decision (which tech goes where) rather than adding AI features at the CRM edge.

Probook attacks ServiceTitan's complexity with AI-native dispatch at the workflow core. Incumbent entrenchment and integration with existing field-service stacks are the main hurdles. a16z's thesis: vertical AI wins by owning the hardest operational decision and expanding outward — dispatch is that node in home services.

• ServiceTitan incumbent

  Dominant home-services ERP with deep entrenchment; heavier implementation than AI-native dispatch layer.

• Housecall Pro direct

  SMB field-service platform; broad feature set but less dispatch-AI depth for enterprise multi-brand operators.

• Jobber direct

  Field service management for smaller contractors; simpler scope than Probook's enterprise dispatch OS.

• Manual dispatch teams incumbent

  Human dispatchers scale linearly with call volume; Probook targets 100:1 tech-to-dispatcher ratios.

Notable stories

• CEO George Eliadis went from pressure-washing jobs to Wharton before building Probook — a16z and Sequoia both cited his trades background as rare among founders selling into home services (Fortune, June 2026).
• One customer booked more than 2,500 jobs in a month with zero human dispatch intervention, per Fortune's exclusive on the Series A — evidence the product handles real volume, not demo calls.
