Problem

Robby addresses the gap between what home-service technicians observe inside a customer’s home and what the business ultimately turns into revenue. HVAC technicians routinely encounter aging equipment, safety issues, and repair or upgrade needs, but paperwork and documentation requirements distract them from servicing equipment and speaking with homeowners. At the same time, homeowners may lack the trust, education, or options needed to understand why a repair or replacement is necessary, leaving otherwise valuable opportunities as zero-dollar jobs.

The economic pain is measurable: Robby says HVAC technicians encounter roughly nine upsell opportunities per day that never get logged, and claims that capturing them can add $135,000 per technician annually. Its blog also says callbacks cost HVAC companies an average of $312 per return visit. The killer use case is therefore an in-home visit where a technician discovers aging equipment or another high-intent need, but lacks the time, information, or customer-ready explanation to turn that observation into a sale.

Product / Service

Robby is a vertical AI growth and documentation platform for home-service businesses. It combines customer, technician, and third-party data to surface dozens of high-intent opportunities each day, gives technicians contextual talking points for customer conversations, captures otherwise-lost insights through lightweight voice AI, and provides general managers with a command center for monitoring pipeline and driving revenue. Its website positions the core service as automating HVAC job documentation and paperwork, while its demo describes an opportunity dashboard that surfaces high-value jobs such as aging equipment.

The intended benefit is to increase close rates and recover revenue without forcing technicians or office teams to adopt an entirely new workflow. Robby uses a book-a-demo sales motion and is best understood as B2B SaaS layered onto existing home-service operations: the technician receives useful context at the job, the office receives more complete documentation and pipeline visibility, and the business gets a systematic way to identify and pursue repair, replacement, and upgrade opportunities.

Market

Robby competes in vertical AI for trades and field-service businesses, initially centered on HVAC but applicable to broader home services such as plumbing and pool service. The opportunity is a large, fragmented U.S. home-services market that a third-party YC-focused analysis estimates at more than $600 billion, with many SMB operators using field-service-management systems. Robby is a narrower revenue-intelligence and technician-assistant wedge rather than a full field-service-management suite.

The competitive set includes ServiceTitan and other CRM or field-service platforms adding AI, as well as more focused tools such as Hatch for home-services follow-up and Laxis. ServiceTitan is both an adjacent competitor and a potential platform risk because it could build or acquire similar functionality. Robby is not pre-revenue: YC says it has several paying customers, each uncovering six figures in additional revenue opportunities per week, and that it helped close $40,000 in new business within its first launch hour. YC lists the company as active in its Winter 2026 batch; the available evidence does not disclose ARR or total booked revenue, although a third-party YC tracker reports nine named customer logos and describes the traction as unusually strong for the batch.
