Probook, a New York-based startup, raised $40 million（約64億円） in funding ($34 million（約54億円） Series A led by Andreessen Horowitz and $6 million（約9.6億円） seed led by Sequoia Capital) to build an AI operating system for home service businesses. The company focuses on dispatch—the scheduling system that decides which technician handles which job—layering on call answering, job data cleanup, and customer updates in one connected platform.
Why it matters
Home service operators have been sold multiple AI tools over recent years but ended up with fragmented systems and rising bills. Probook's early customers report concrete results: one Indiana operator with 260 technicians booked 2,542 jobs in its first month with zero manual intervention; a Florida operator cut its dispatch staff from 22 to 10; a Kansas shop grew average job revenue by 20%. The timing aligns with a structural opportunity—private equity-backed home services rollups (which consolidate local shops) are growing at 88% year-over-year through mid-2025 and are focused on margin optimization.
What to watch
ServiceTitan, a $6.3 billion（約1兆円） publicly traded company, dominates software for home service businesses and already offers its own AI scheduling product. Probook is currently listed as a ServiceTitan partner (the two work together rather than compete), but ServiceTitan has $960 million（約1500億円） in revenue and its own engineering team. Founder George Eliadis, who pressure-washed houses for six summers before attending Wharton, was the company's only salesperson until February of this year.
