Avoca Hits $1B Valuation With $125M Round to Bring AI to HVAC and Trades

Avoca, a Y Combinator-backed startup building AI agents for plumbers, HVAC technicians, and roofers, has raised more than $125 million at a $1 billion valuation. The Series B round was led by Meritech and General Catalyst, with continued backing from Series A investors Kleiner Perkins and Amplify Partners.

The deal vaults a relatively low-profile vertical AI company into unicorn territory, and it marks one of the clearest signs yet that investors see the biggest near-term AI opportunity not in chatbots — but in the unsexy back offices of America's services economy.

What Avoca Actually Does

Avoca builds AI agents that answer the phone, schedule jobs, follow up on quotes, and run dispatch for service businesses. The customer base is exactly what you'd expect from a company that picked HVAC and plumbing as launch verticals: small and mid-sized contractors, regional franchises, and the sort of operators who run their entire business out of a truck and a CRM.

The platform handles inbound calls, texts, and chats around the clock. When a homeowner calls at 8 PM about a broken AC unit, Avoca's agent picks up, qualifies the lead, books the job into the contractor's existing dispatch software, and follows up the next morning if the technician's quote needs a nudge.

The company says it's grown from its first 10 customers to more than 800 today, largely through trade shows and word of mouth. Avoca is on track to book $1 billion worth of jobs in 2026 alone, and the platform is at "eight figures" in annual recurring revenue.

Why HVAC, Why Now

Avoca's pitch to investors is that the services economy is the biggest pool of fragmented, AI-ready demand in the US. The HVAC industry alone was worth roughly $50 billion in 2025, with some analysts projecting $75 billion by 2032. Plumbing, roofing, and electrical add tens of billions more.

The structural problem these businesses face is simple: missed calls. A typical HVAC contractor misses 20% to 40% of inbound calls during peak demand hours. Each missed call is a job that goes to a competitor — and in trades where margins per job range from a few hundred to a few thousand dollars, the lost revenue compounds quickly.

Hiring more dispatchers has historically been the answer, but labor is the single hardest cost line for service businesses to scale. AI agents that work 24/7, never miss a call, and integrate with existing field service management software fix the bottleneck without adding payroll.

The Founders and the Origin Story

Avoca was founded by Tyson Chen and Apurva Shrivastava, both MIT graduates, after what they've described as a chance encounter in Texas with a contractor who couldn't keep up with inbound demand. The pair started by manually answering calls for a single HVAC company, learning the workflow, and then building software that replicated it.

That hands-on origin story shaped the product. Unlike horizontal AI agent platforms, Avoca's system is tuned for the specific way a dispatcher in the trades thinks about a call — what the customer needs, which technician is available, what the truck inventory looks like, and how to upsell a maintenance contract without sounding pushy.

What Investors Are Saying

Leigh Marie Braswell, partner at Kleiner Perkins, framed the bet on Avoca around execution rather than just AI capability. "What excites me about Avoca is that they're applying AI where execution is the real bottleneck," she said. "Tyson and Apurva have built something that feels less like a tool and more like core infrastructure for how this industry operates."

That framing — AI as core infrastructure for an industry, not as a feature — is the thesis driving most of the recent capital flowing into vertical AI startups. Investors are increasingly skeptical of horizontal LLM wrappers and looking for companies that own a specific workflow end-to-end.

How Avoca Compares

Several startups are chasing the same prize. Rilla, Service Titan's AI add-ons, and a handful of newer entrants all target service businesses with various forms of AI automation. What sets Avoca apart, according to the round's investors, is how deep the platform goes — answering calls is the entry point, but the system also handles follow-ups, reactivation campaigns, technician dispatch, and post-job surveys.

The company's growth from 10 to 800 customers in roughly two years suggests the workflow integration is sticky. Service businesses don't switch software lightly, and an agent that's already plugged into a contractor's CRM, calendar, and payment system creates real switching costs.

What's Next

Avoca says the new capital will go toward expanding the agent platform into adjacent verticals — electrical, pest control, garage door installation — and deepening the product for existing trades. The company is also hiring across engineering, sales, and customer success, with plans to roughly double headcount over the next year.

A bigger question is whether Avoca attempts to expand beyond inbound communication. The natural next step is sales — agents that proactively reach out to past customers about maintenance contracts or seasonal services. That's a meaningfully different product, and one that several trades software companies are building toward simultaneously.

Bottom Line

Avoca's $1 billion valuation says less about the company than it does about where AI investment dollars are heading in 2026. Horizontal LLM platforms are facing margin compression and intense competition. Vertical AI applications — especially in fragmented industries with clear ROI from labor automation — are where investors see durable returns. If Avoca executes on its expansion plan, the $50 billion HVAC market alone could support a much larger company. The trades aren't a glamorous AI use case, but they may turn out to be one of the most lucrative.
