San Francisco's Broccoli AI, which builds AI agents for plumbing, HVAC and electrical contractors, has raised $52 million across its Series A and Series B, according to Fortune. Khosla Ventures led both rounds, with Y Combinator and Operator Partners also participating. The Series B was $30 million and the Series A, which had not been announced before, was $22 million, with the two rounds coming 9 months apart. Fortune also reported a $300 million post-money valuation, citing a person familiar with the matter, and Broccoli declined to comment on that figure.
For founders building AI products for industries far from Silicon Valley, the story is worth reading closely. Broccoli's path runs through a plumbing company in Sacramento, and the way it got there says a lot about how vertical AI gets built in 2026.
What Broccoli actually sells
Broccoli's agents answer inbound calls, book jobs directly into the scheduling software a contractor already uses, follow up on open estimates and renew service memberships, as Fortune describes it. The company's own site lists separate agents for customer service, reception, sales, open estimates and appointment reminders, with integrations for ServiceTitan, Salesforce, AccuLynx and Housecall Pro. Over the past 7 months, it has added roofing, pool care, garage doors, home improvement and exteriors to its original trades.
The company says more than 1,500 businesses now use it, including Ace Hardware Home Services, Mr. Electric and Any Hour Group. CEO Abhishek "AJ" Jain told Fortune that revenue has tripled since the Series A, and headcount has grown from 15 people a year ago to more than 150. Jain and cofounder Aditya Ketkar went through YC in the Winter 2022 batch and raised a $1.5 million seed afterward, per Fortune, which also notes that the company's San Francisco office shares a parking lot with Cognition.
If you've followed the rise of AI agents that can take real actions, Broccoli is a good example of what that looks like outside of software teams. The agent picks up the phone at 2 a.m., figures out whether a burst pipe is an emergency and books the job into ServiceTitan, which is the work that usually falls through the cracks at a small contractor.
The first customer became an executive
For early founders, the origin story in the Fortune piece is worth reading twice. Marcelle Flowers was trying to sell her Sacramento plumbing business, Armstrong Plumbing, when Broccoli approached her. She told Fortune she gave the founders 5 minutes. She was paying $5,000 a month for an answering service that booked jobs into her software 33% of the time, which was the kind of concrete pain a small AI team could measure and fix.
Flowers became Broccoli's first customer, then an adviser, then its COO, according to Fortune. The company's site now lists her as Chief Industry Officer. In a testimonial on that site she credits the founders with sitting with her team and learning the business before building anything. Jain described her to Fortune as "the soul of the company."
This pattern shows up again and again in vertical software. The founders who win usually find one operator who knows the industry cold and earn their trust before they write much code. We covered the mechanics of that in our guide to founder-led sales and landing your first 10 customers, and Broccoli is close to a textbook case.
3 lessons for founders building vertical AI
The first lesson is to price against the thing customers already pay for. Broccoli's pitch to Flowers was easy to evaluate because she had a monthly answering service bill and a booking rate she could compare. Jain told Fortune the AI does work equivalent to roughly 30% of a typical contractor's office staff and is "maybe good at like 80% of the tasks," with emergencies still going to people. Being upfront about the 20% it can't handle makes the 80% easier to buy.
The second lesson is to plug into the system of record instead of replacing it. Contractors live in ServiceTitan and Housecall Pro, and Broccoli writes jobs straight into those tools. That lowers the switching cost to almost nothing, which matters a lot in industries where the owner is also running jobs in the field.
The third lesson is that unglamorous markets can grow fast. Home services rarely shows up on demo day slides, yet Broccoli went from 15 to more than 150 people in a year. Guidewire's recent purchase of hyperexponential, which we broke down in our post on what the $1.7B deal means for AI startups, points the same way. Incumbents and investors are paying for AI that does specific, regulated or messy work in a single industry.
What it means for operators and job seekers
Fortune reports the new money will go toward hiring engineers and salespeople and speeding up product development. Broccoli's YC company page currently lists open roles across operations, engineering and product, including account executive, staff software engineer and senior product manager positions. For Bay Area engineers who want to work on voice agents with real customers, vertical AI companies like this one are worth a look alongside the big labs.
Jain framed the work in a way that runs against the usual fears about AI and jobs, telling Fortune the product is "making jobs." Whether that holds across the trades is a fair debate, and founders in this space should be ready to have it with customers.
Where Bay Area founders compare notes on this
AI-native companies were the subject of one of our October evenings. On October 21 we hosted Inside Native AI Companies with Gokul Rajaram in Redwood City, and you can still see the event page here. That evening was part of South Bay Renaissance, the effort Tribe coordinates to rebuild the startup and social scene across the Peninsula and South Bay in person, one founders' dinner and demo night at a time. If you're building in the Peninsula or the South Bay, our guide to where to meet founders in the South Bay and Palo Alto has more places to start.
If you want to keep talking about AI agents, vertical AI and which tools are actually working for small businesses, the AI Trends Tribe is where those conversations happen between events. And to hear about the next founder dinner, AI talk or demo night before it fills up, follow the Tribe Events calendar on Luma.
