Probook, a startup building dispatch and scheduling software for home service businesses, has raised $40 million in a funding round led by Andreessen Horowitz and Sequoia Capital. The company aims to replace the fragmented tools and paper-based systems still used by many plumbers, electricians, and other trades.
The Series B round includes participation from existing investors, bringing Probook’s total funding to over $60 million. The company did not disclose its valuation but said the capital will be used to expand its engineering team and accelerate product development.
Probook operates in a crowded market that includes players like ServiceTitan, Housecall Pro, and Jobber. However, the startup differentiates itself with a mobile-first approach tailored specifically for small crews and solo operators. The home services industry, valued at over $500 billion annually, has been slow to adopt modern software solutions.
For Probook, the challenge will be scaling its customer base while competing against well-funded incumbents. The company claims it has already onboarded thousands of businesses since its launch, with revenue growing threefold year-over-year.
Founder and CEO Jake Thompson, who spent his summers pressure washing houses with his father, said the funding validates the need for tools built by people who understand the trades. “We’re not just building software for service pros — we’re building it with them,” he said.
