EliseAI Raises $350M at $4B Valuation for Housing and Healthcare AI

EliseAI on Tuesday, 29 September 2026, said it raised $350 million at a $4 billion valuation. TechCrunch reported the round was co-led by Andreessen Horowitz and Bessemer Venture Partners and that the new valuation is double what EliseAI was worth at its Series E last August. Reuters reported participation from Ontario Teachers’ Pension Plan, Sapphire Ventures, and Navitas Capital, and said EliseAI was valued at $2.2 billion in a Series E round in 2025; Fortune puts that $2.2 billion round roughly 13 months before this one. Reuters and EliseAI’s GlobeNewswire release say the New York–based company will use the capital to expand its engineering, deployment, and sales teams and to establish San Francisco as a second engineering hub, while the release adds that the money will help automate more of its customers’ housing and healthcare operations.

Why housing and healthcare AI is drawing this capital

EliseAI automates administrative and operational work for landlords and health systems—leasing, maintenance, renewals, billing, patient scheduling, intake, and front-desk workflows. TechCrunch notes the company was founded in 2017, says its software is used by one in six U.S. apartments, and reports EliseAI passed $200 million in annual recurring revenue this summer. The GlobeNewswire release adds that more than 30 million Americans have interacted with EliseAI since founding. Those scale metrics explain why growth investors keep writing larger checks into vertical agent companies rather than only horizontal chatbots.

CEO and co-founder Minna Song told TechCrunch that housing and healthcare are two of the largest expenses for American households, which is why EliseAI embeds agents directly into those operations instead of selling a generic assistant. Earlier in September the company launched Apollo, an AI “teammate” built into the same platform that already runs leasing, maintenance, and renewals so it can act across property-team roles. On the healthcare side, Song described automation from first inbound call through referrals, scheduling, insurance verification, chart prep, and follow-up. That product story sits alongside broader enterprise agent packaging PromptCrates has covered, such as Meta’s Enterprise Platform under CJ Desai and workplace agent surfaces in Microsoft Copilot Home, Code, and Autopilot.

Fortune’s exclusive notes this is the fourth time since 2023 that a16z and Bessemer have backed EliseAI together, and that Ontario Teachers’ Pension Plan is a new investor in the round. The company moved this summer into a 109,000-square-foot Manhattan office in the former Tiffany & Co. building on Fifth Avenue, signaling a physical footprint that matches a multi-billion-dollar valuation narrative. Song was noncommittal on IPO timing, telling Fortune the focus is building the best business rather than a fixed public-market calendar.

Where the new money is supposed to go

According to Reuters and the company release, the money will expand engineering, deployment, and sales teams, with San Francisco named as a second engineering hub beside the New York headquarters. The release says that hiring spans EliseAI’s North American offices, and its company boilerplate lists existing teams in San Francisco, Boston, Chicago, Austin, and Toronto. For customers, the near-term question is whether Apollo and deeper healthcare intake automation ship faster, and whether deployment capacity keeps up with the one-in-six apartments installed base when every new property still needs integrations, training, and change management.

Investors are also underwriting a thesis that agentic automation in regulated, high-churn service industries can compound faster than consumer model apps. Housing operators care about vacancy days and maintenance SLAs; specialty physician groups care about referral leakage and insurance verification delays. If EliseAI can keep owning those workflows while model costs fall—Song’s public framing in the company blog is that intelligence is getting cheaper and life should too—then ARR growth can outpace token-price wars among frontier labs. That is a different bet from pure model-company fundraising such as the OpenAI raise chatter PromptCrates covered in OpenAI’s reported $30B raise at $1.4 trillion.

Diligence points for operators and rivals

Property and health-system buyers evaluating EliseAI after this round should ask three diligence questions. First, what data-residency and BAA terms apply when Apollo touches patient scheduling or insurance data. Second, how human oversight works when agents send resident messages or change maintenance priorities. Third, whether the $200 million ARR figure is concentrated in a few enterprise accounts or diversified across the apartment long tail. Competitors in proptech and healthcare RCM will watch whether San Francisco engineering capacity translates into faster connector coverage or only into sales headcount.

For the wider AI market, EliseAI’s jump to $4 billion is another data point that vertical workflow agents with measurable operating metrics can still raise large private rounds even as model labs dominate headlines. The story is less about a new foundation model and more about distribution inside the systems that already run apartments and clinics. Watch whether Apollo becomes the default interface for property teams and whether healthcare paperwork automation expands beyond specialty groups into broader ambulatory networks.
