Khosla Ventures Leads $52 Million Into Broccoli AI, Which Answers the Phone for Plumbers and HVAC Crews

While most AI funding headlines go to foundation models and data centers, one of the weekend's more revealing rounds went to the other end of the market. Broccoli AI, which builds phone-answering and scheduling agents for plumbing, HVAC and electrical contractors, has raised $52 million across two rounds — a $22 million Series A and a $30 million Series B — led by Khosla Ventures, with Y Combinator and Operator Partners participating, according to FinSMEs and Fortune. A source familiar with the company's financials told Fortune the valuation is $300 million post-money. The company itself has not confirmed the valuation.

The two rounds closed within roughly nine months of each other, on top of an earlier $1.5 million seed. The product targets the unglamorous first mile of the trades business: answering inbound calls around the clock, booking jobs, gathering pre-visit information about a property and its service history, following up on estimates that customers left unanswered, and renewing service memberships before they lapse. Contractors pay for it because a missed after-hours call is a lost job, and the average HVAC or plumbing company loses plenty of them.

Traction figures are company-reported: more than 1,500 businesses served, revenue tripled since the Series A, and a workforce of about 160 split between San Francisco and Utah, blending engineers from Microsoft, Amazon and Uber with veterans of the home services industry. Founders AJ Jain and Adi Ketkar previously built a Y Combinator-backed venture together. Broccoli has also expanded from its core three trades into roofing, pool care and home improvement.

The case study the company leads with: one multi-location national client reported a 29 percent revenue increase and a 36 percent reduction in overhead costs in their first year on the platform. Those numbers come from Broccoli's own marketing and should be read as such — no independent audit accompanies them, and client selection bias in vendor case studies is the industry norm.

The investment logic is the classic vertical AI argument. Horizontal SaaS has repeatedly failed in the trades because the market is fragmented by geography and specialty, the software is bought by owner-operators rather than IT departments, and the workflows — dispatch logistics, intake forms, estimate follow-up — are too idiosyncratic for generic tools. A model trained on plumbing intake calls, job tickets and technician scheduling encodes domain knowledge that a general-purpose assistant lacks, and the data flywheel compounds with every call answered.

Khosla Ventures has been among the most aggressive backers of that thesis, and the round fits a broader pattern of 2026 capital flowing into vertical agents for unsexy industries — IT and HR ticketing, insurance underwriting, medical billing — while horizontal agent platforms fight over the same enterprise budgets. The US home services market is measured in the hundreds of billions of dollars annually, and its administrative layer is still run on phones, paper and duct-taped software.

The open questions are the ones that decide every vertical AI company: retention, integration depth and whether the phone agent survives contact with an angry customer at 11 pm. Broccoli's revenue tripling and Khosla leading two rounds in nine months suggest the early signals are good. Whether AI agents become the default front office for the trades — or just a better answering machine — will be settled by contractors renewing, not by venture capital.
