EliseAI $350M Round Lifts Housing AI Startup to $4B Valuation

A larger round than the rumors suggested

EliseAI, a New York company that automates office work for landlords and specialty medical practices, has raised $350 million at a $4 billion valuation.12 Andreessen Horowitz (a16z) and Bessemer Venture Partners led the round. Ontario Teachers' Pension Plan, Sapphire Ventures and Navitas Capital also took part.11 Axios described the $4 billion figure as a post-money valuation.15

The final terms beat what had been reported earlier. In mid-August, Business Insider reported that a16z and Bessemer were negotiating to lead a $300 million round at a $3.7 billion valuation, and warned that the figures could change.2 When the round closed, both the amount and the price were higher.1617 For a late-stage AI company in 2026, that matters. A deal that grows between the leaked term sheet and the announcement usually means investors were competing to get in, not that the company had to cut its price to finish raising.

The round is entirely primary capital. CEO and co-founder Minna Song said all of the money goes to the company and none of it comes from existing shareholders selling stakes.516 Many recent mega-rounds have included large secondary sales that let founders and early employees cash out. That makes this structure worth noting: the full $350 million will go into running the business.

From unicorn to $4 billion in about two years

EliseAI's valuations over the past two years show how much investors now pay for vertical AI companies that are growing fast. In August 2024, a $75 million Series D led by Sapphire Ventures valued the company at more than $1 billion.89 A year later, a $250 million Series E led by a16z valued it at $2.2 billion. Reuters reported at the time that the valuation had doubled.3 The new round arrived about 13 months after that and nearly doubles the price again.513

The coverage does not all count the a16z relationship the same way. Fortune reports that this is the fourth time EliseAI has raised from a16z and Bessemer since 2023.5 An analysis from Dakota says a16z has led or co-led three rounds in a row.13 Both accounts support the main point: the biggest checks are coming from investors who already own a stake and know the business well. Song described it the same way, saying the existing backers had watched the company closely over the past year and chose to invest more.1

The round has no letter. One tracker lists it as an unlettered growth financing, not a Series F.17 Late-stage companies increasingly drop the letters, which can make them look like they are running out of the alphabet. The economics are the same either way: this is a late-stage growth round for a company that could plausibly be considered for an IPO.

The lead structure is also described a little differently. The company's announcement says a16z and Bessemer led, and lists Ontario Teachers' as a participant.11 Fortune's report, as syndicated, describes the pension fund as joining the co-leads.5 The safer reading follows the company's own announcement: a16z and Bessemer led, and Ontario Teachers' was the main new investor. Bessemer partner Sameer Dholakia is joining the board.12

The revenue behind the price

The valuation rests mainly on growth. In June 2026, EliseAI said it had passed $200 million in annual recurring revenue (ARR) and had doubled revenue year over year for five years in a row.11 It had crossed $100 million in ARR in early 2025, so the next $100 million took roughly a year and a half.23

Tech Funding News calculates that the round values EliseAI at about 20 times ARR at most, and notes that the multiple may now be lower because the revenue figure dates from June.16 Venture Capital Tracker reaches the same rough multiple but points out what is missing: ARR is not audited revenue, and the company has not disclosed gross margins, losses, cash burn or profitability.17 An analysis from Center Consulting adds more caveats. The "one in six apartments" claim is not defined, and the announcement includes no figures on AI accuracy, error rates or customer churn.18

Those caveats are fair. Still, a company that keeps doubling revenue at more than $200 million would normally justify a premium multiple even outside an AI boom. The stronger argument for the price is that the growth is coming with deep market penetration. The company says its software now powers one in six U.S. apartments.11 That is up from about one in twelve multifamily units at the time of the Series D, and roughly 10% of the market at the Series E.83 Dakota reports that about 70% of the 50 largest U.S. rental operators are customers.13 Tech Funding News says its AI agents handle about 5 million calls a month.16

Where the money goes

EliseAI says the money will pay for product development and for larger engineering, deployment and sales teams across North America. It will also make San Francisco a second engineering hub alongside its New York headquarters.12 The company moved this summer into a 109,000-square-foot office in Manhattan's former Tiffany & Co. building on Fifth Avenue.1 Venture Capital Tracker reads the San Francisco expansion as a move to compete for AI engineers with frontier labs and general-purpose AI startups, while keeping its main base close to real-estate and healthcare customers.17

On the product side, the company recently launched Apollo, an AI agent built to complete tasks across the whole platform, not just one narrow job.6 Dakota reports that Apollo passes binding or judgment-heavy decisions back to human staff.13 Coverage of Apollo's scope varies. Some accounts describe it mostly as a leasing follow-up tool and a way to look up information.207 Others present it as a general teammate that can take on any task.4 The difference matters because the pitch to investors depends on EliseAI moving from answering renters' messages to running whole operational processes. Yahoo Finance argues that if operators hand over complete tasks such as maintenance coordination and renewals, the industry conversation shifts from response times to how many staff a property needs on site.14

The healthcare bet

Healthcare is the second business, and the more uncertain one. EliseAI entered healthcare in 2023.8 A dedicated unit now automates the patient process for specialty physician groups, from the first phone call through referrals, scheduling, insurance checks, chart preparation and follow-up.11 Relve reports that the company works with more than 3,500 healthcare organizations.20 EliseAI was also recently named a co-development partner for agentic voice AI with Nextech, which sells software to specialty practices.12

Analysts mostly agree on the risks. Dakota points to long procurement cycles, compliance burdens, and integration with electronic health record systems that can slow deployment.13 Relve makes a similar point, arguing that integrations, security and proven return on investment will decide which vendors win.20 AI Press Room adds a structural concern on the housing side. Because EliseAI builds on top of property-management systems such as Yardi and RealPage, it depends on those platforms.4 Earlier criticism is worth remembering too. In 2024, TechCrunch cited reviews saying the chatbots sometimes failed to bring in human staff when they should have.9

What the round says about venture capital in 2026

The deal fits a pattern of investors writing fewer, larger checks to a small number of scaled AI companies. Yahoo Finance, citing Creti, reports that global proptech venture funding reached $4.53 billion across 231 deals in the first half of 2026. That is about 65% below the 2021–2022 peak, and mega-rounds took nearly half the capital.14 On its own, EliseAI's raise equals almost 8% of that half-year total.14

Dakota describes the round as a second wave of AI investment. After the first wave funded foundation-model builders, money is now moving to application companies with strong industry distribution and high switching costs.13 That framing holds up, with one qualification: investors are not rewarding vertical AI as a category. They are rewarding the few vertical players that have already won their market. EliseAI got into housing early, became part of how its customers operate, and is now trying to repeat that in healthcare. At about 20 times ARR, the price assumes it will succeed.16 The next 12 to 18 months will show whether Apollo and the healthcare business turn into revenue that supports the valuation.13

Song would not commit to an IPO, saying the company has no specific timeline.1 With $350 million in new primary capital and growth still near 100% a year, EliseAI has no near-term need to go public.
