Overview
- Probook closed $34 million in a Series A led by Andreessen Horowitz plus a prior $6 million seed from Sequoia, bringing total reported capital to $40 million, the companies confirmed on Tuesday.
- The company says it has built a dispatch-first AI operating system that automates call intake, booking, technician assignment, and customer updates so the scheduling workflow drives all other functions.
- Early deployments report large efficiency gains with one multi-location customer booking thousands of jobs in a month without human intervention and other operators increasing technician-to-dispatcher ratios while cutting dispatcher headcount.
- Probook sells to independent operators and private-equity rollups that are centralizing local shops, and the startup plans to use the new capital to scale product and go-to-market work as adoption grows.
- ServiceTitan remains the dominant incumbent with its own AI scheduling product, so Probook currently lists as a ServiceTitan partner and faces the risk of direct competition even as it tries to win customers and prove dispatch-first value.
