Probook Secures $40 Million to Scale AI Operating System for Home-Service Trades
A 24‑year‑old Wharton graduate turned his pressure‑washing experience into an AI‑powered operating system that just raised $40 million in venture capital. On June 23, 2026, Probook announced a total raise that includes a $34 million Series A led by Andreessen Horowitz and a $6 million seed round led by Sequoia Capital, with Sequoia also participating in the Series A.
George Eliadis founded Probook after noticing a common pain point among small electricians, plumbers and HVAC technicians: the difficulty of dispatching crews to the many jobs they receive, which can cause missed revenue. "I started Probook to solve a problem in my own business," he wrote on the company’s website. Eliadis began his career pressure‑washing houses with his father in upstate New York before earning a degree from Wharton.
Probook’s platform claims to streamline the entire operational backbone of a home‑service shop. By integrating scheduling, customer communication, job data cleanup and other workflow functions into a single system, the AI operating system can answer calls, assign technicians based on experience, availability and proximity, and keep customers updated with estimated arrival times. The company markets the platform as a replacement for the fragmented set of tools many trades firms currently use.
Case studies illustrate the system’s impact. An Indiana‑based repair service with 14 locations and 260 technicians reportedly booked 2,873 jobs in its first month on Probook without any human intervention. A Kansas business that adopted the platform for eight months reported a 10 % increase in revenue per job while operating with a 40 % smaller team. Probook also sells its software to private‑equity firms that are consolidating home‑service operators and looking to improve margins through automation.
Sequoia Capital described Probook as "an easier, faster way to book repairs for your home." In a blog post, Sequoia partner Konstantine Buhler explained that the platform’s AI "picks up immediately, already knowing each technician’s experience, availability and distance from your home, along with their close rates and ticket sizes. It assigns the right tech to the job, alerts them, and keeps you in the loop with an ETA." Buhler added that most founders building for the trades have never worked in them, whereas Eliadis has.
Probook is currently listed as a partner of ServiceTitan, a $6.3 billion publicly‑traded company that provides customer‑relationship management software for tradespeople. ServiceTitan also offers an AI scheduling product. The partnership means the two firms cooperate rather than compete, according to Fortune.
The company’s focus on a unified platform contrasts with the fragmented AI solutions that many home‑service firms have adopted over the past three years. Eliadis said, "The problem isn’t AI. It’s that AI sat on top of a fragmented system. That’s what got us here. The next decade will be won by the platform that runs the customer experience end to end, where AI does the bulk of the work and your team manages the exceptions. Not five tools and three vendors. One platform that runs it all."
While Probook’s funding and early results demonstrate a growing appetite for AI‑driven operational tools in the home‑service sector, the company still faces competition from established players like ServiceTitan. The partnership with ServiceTitan may help Probook navigate that challenge, but the company has not yet announced plans to develop a separate scheduling product that could directly compete with ServiceTitan’s offering.
Probook’s recent capital raise positions it to expand its platform across the United States, enhance its AI capabilities and pursue additional partnerships with private‑equity firms and large service operators. The company has not yet disclosed a timeline for new product releases or a detailed roadmap for scaling beyond its current customer base.
In summary, Probook has secured $40 million to accelerate the deployment of its AI operating system for home‑service businesses. The platform claims to consolidate scheduling, communication and operational workflows into a single system, and early adopters report increased revenue and reduced staffing needs. The company remains partnered with ServiceTitan and is targeting further growth through private‑equity relationships and broader market penetration.
