Robby Turns Every HVAC Service Call Into a Revenue Opportunity

The Macro: Home Service Companies Leave Money on the Floor Every Day

Home service businesses like HVAC, plumbing, and electrical companies have a unique advantage that most businesses do not: they send trained technicians inside customers’ homes multiple times a year. Every service call is an opportunity to identify additional work. An HVAC technician servicing a furnace can spot that the water heater is aging, the ductwork needs sealing, or the AC unit should be replaced before next summer.

But most technicians are not salespeople. They fix what they came to fix and leave. The business loses the upsell opportunity, and the homeowner is left with aging equipment that will fail eventually.

On the lead generation side, home service companies typically rely on HomeAdvisor, Angi, and local advertising. These channels are expensive and competitive. Meanwhile, the company is sitting on a goldmine of customer data: past service records, equipment ages, home characteristics, and seasonal patterns that could predict which customers need service next.

Robby, backed by Y Combinator, is an AI growth engine that attacks both sides of this problem. It generates new leads from existing customer and third-party data, and it arms technicians with context and talking points to increase close rates on every visit.

The Micro: A Command Center for Revenue

Vineet Jammalamadaka, Feroze Mohideen, and Joseph Schwarzmann built Robby as a single command center for home service revenue. The product has three phases: pre-job preparation that gives technicians customer context and equipment history, on-demand support during service visits with upsell opportunities and product recommendations, and automatic documentation that syncs to ServiceTitan.

The claimed results are strong: $135K additional revenue per technician per year, 15% fewer callbacks, and 92% recommendation rate. If those numbers hold across a typical home service company with 20 technicians, that is $2.7M in additional annual revenue.

The ServiceTitan integration is critical. ServiceTitan is the dominant field service management platform for home service companies. Any tool that does not integrate with it is dead on arrival in this market.

The company raised $500K from YC and works with established home service companies including Abe, Barrett, Blue Knight, and Minuteman. These are real companies with real revenue, not demo accounts.

Competitors include ServiceTitan’s own analytics features, Successware, and various CRM tools adapted for home services. But none of them combine lead generation from data analysis with real-time technician enablement in a single platform.

The Verdict

Robby has found a large, proven market with a clear pain point. Home service companies want more revenue per truck roll, and most lack the tools to achieve it.

At 30 days: what is the average increase in ticket size for service calls where the technician uses Robby’s recommendations?

At 60 days: how many leads is Robby generating per company from existing customer data, and what is the conversion rate?

At 90 days: is Robby expanding beyond HVAC into plumbing, electrical, and other home service verticals?

I think Robby is well-positioned. The home service market is enormous, fragmented, and underserved by modern software. An AI tool that demonstrably increases revenue per visit sells itself. The $135K per technician per year claim, if validated across multiple companies, makes Robby an obvious purchase for every home service business in the country.
