EliseAI Raises $350M at $4B to Automate Housing, Healthcare

EliseAI has raised $350 million at a $4 billion valuation, doubling its worth in just over a year on the strength of AI agents that do the unglamorous work nobody else wants to automate. The New York-based company announced the round on September 29, 2026, with Andreessen Horowitz and Bessemer Venture Partners co-leading, TechCrunch reported.

The financing brings in the Ontario Teachers' Pension Plan as a new investor alongside existing backers Sapphire Ventures and Navitas Capital. Nearly all of the company's major existing investors followed on in the round, which consisted entirely of primary-market equity. CEO and co-founder Minna Song told Fortune there was no secondary sale for early investors or employees. It is the fourth time the company has raised capital from Andreessen Horowitz and Bessemer since 2023, according to reporting on the raise.

The new price tag nearly doubles the $2.2 billion valuation EliseAI carried after its $250 million Series E roughly thirteen months ago. Song credited execution rather than any single breakthrough for the climb, pointing to deeper expansion within housing and healthcare, more products per customer, and growing market penetration. Investors, she said, are rewarding the compounding effect of that work.

The boring corners of the economy are an agentic goldmine

EliseAI does not sell a general-purpose assistant to knowledge workers, and it does not build consumer chatbots. It embeds AI agents directly into the operating systems of housing and healthcare, the places where a ringing phone at 2 a.m. is either a tenant with a maintenance emergency or a prospective renter asking about a one-bedroom. As RecodeX Pro put it, the company works in the corners technology forgot: the calls, tickets, and paperwork that make up some of the most stubborn operating costs in the economy.

On the housing side, the agents handle leasing conversations, renewals, maintenance coordination, collections, and the steady stream of resident questions that arrive at all hours. On the healthcare side, they manage patient intake, referrals, scheduling, insurance verification, chart preparation, and follow-ups for specialty physician groups. The pitch is that nothing falls through the cracks in workflows where a dropped ball has real consequences for tenants and patients.

Scale is the part of the story investors seem to believe most. The company says its platform now touches roughly one in six apartments in the United States. More than 30 million Americans have interacted with it since the company's 2017 founding, and its housing and healthcare businesses together handle about five million calls a month. Those figures are company-reported and have not been independently verified.

By the numbers: five years of doubling

The revenue line behind the valuation looks unusually consistent. EliseAI said in June that it had crossed $200 million in annual recurring revenue, doubling revenue year over year for the fifth consecutive year. For enterprise software that is a rare streak, and it helps explain why the same two firms kept leading rounds instead of the company shopping for new marquee names.

The fresh capital will accelerate product development and expand the engineering, deployment, and sales teams across North America. The Commercial Observer reported that the company plans to establish San Francisco as a second engineering hub alongside its Manhattan headquarters. Song told the publication the company is hiring across engineering, deployment, and sales in New York, Boston, Chicago, Austin, and Toronto.

Apollo and the platform push

Earlier in September, EliseAI launched Apollo, an AI teammate built natively into the EliseAI environment. Rather than a standalone product, Apollo is designed to act across every role on a property team, assisting with leasing, maintenance, and renewals inside the same system that already runs those workflows. The framing matters: the value proposition is not a smarter chatbot but an agent that already knows the state of the building it is working in.

That embedded approach is the company's bet on how vertical AI agents win. A general assistant can draft a lease renewal email, but it does not know which units are turning over, which maintenance tickets are open, or what the renewal pipeline looks like next month. Apollo inherits that context because it lives where the work happens.

What the raise says about vertical AI agents in 2026

The round is another data point in a clear investor shift: from horizontal copilots toward agents that automate specific, high-cost industry workflows end to end. Reuters reporting on the raise noted the funding underscores growing investor interest in AI companies that take on complex, industry-specific administrative workloads. The Bank of America Institute found that AI spending growth among mid-sized firms peaked in August, with adoption concentrated in service industries such as healthcare and education for documentation, communication, and administrative tasks.

Song has said the company targeted housing and healthcare deliberately because they represent two of the largest expenses for American households. That choice also puts EliseAI in the most trust-sensitive corner of the agent economy. An agent that misroutes a maintenance request is an annoyance; one that mishandles patient scheduling or insurance verification is a liability. The same governance questions facing the industry, from data controls to auditability, apply here with the volume turned up. Recent industry moves toward formal AI self-regulation, like the accord signed with six AI CEOs this week, show how quickly trust infrastructure is becoming part of the enterprise AI conversation.

For now, the market is rewarding the vertical playbook. EliseAI has turned five years of doubling revenue into a $4 billion valuation without relying on a consumer breakthrough or a foundation-model moonshot. Its agents answer phones, schedule patients, and chase renewals in the background while the industry debates what agents should be allowed to do.
