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

A $350 million vote for vertical AI

On September 29, EliseAI, the New York company that automates administrative work for landlords and medical practices, announced that it had raised $350 million at a $4 billion valuation.8 Andreessen Horowitz and Bessemer Venture Partners led the round. Ontario Teachers' Pension Plan, Sapphire Ventures and Navitas Capital also took part.16 The new price is nearly twice the $2.2 billion valuation from EliseAI's $250 million Series E, which closed about 13 months earlier.1

The headline numbers are consistent across the coverage. The more interesting points are about how the deal is structured, how quickly the valuation rose, and what investors are paying for. Taken together, the reporting shows late-stage venture capital in 2026 rewarding a narrow kind of AI company: one that already has large, recurring revenue inside a specific industry. Promises about the future count for less.

The terms: all primary, mostly familiar names

CEO and cofounder Minna Song told Fortune that the round was made up entirely of primary capital. All of the money goes to the company, and no early shareholders or employees sold stock.1 That matters at a time when many large late-stage rounds include secondary sales that let insiders cash out. A fully primary raise suggests the existing investors would rather add to their stakes than reduce them. According to Fortune, nearly all of EliseAI's major existing backers joined the round.1

Outlets describe the investor roles somewhat differently. Fortune reported that Ontario Teachers' co-led alongside a16z and Bessemer.1 The company's own announcement, which Ontario Teachers' republished, names only a16z and Bessemer as leads and lists the pension plan as a participant.8 Most trade outlets follow the press release.1619 Either way, a large pension plan writing a check is a sign that money usually reserved for later-stage, lower-risk deals now sees EliseAI as a durable business rather than a speculative one.11

Accounts of how often the two lead firms have backed EliseAI also differ. Fortune called this the fourth time EliseAI has raised from the pair since 2023.1 Reuters' coverage of the 2025 Series E, however, said a16z led that round and Bessemer joined it.3 One funding tracker records Bessemer's first check as August 2025.5 One aggregator even claimed Sapphire led the Series E, which conflicts with Reuters' contemporaneous report.10 Reuters' account of a16z as lead is the most reliable. What matters for this round is that both firms decided to invest more after a year on the cap table, and that Bessemer partner Sameer Dholakia joined the board.117

The round also grew while it was being negotiated. In August, reports said EliseAI was in talks to raise about $300 million at a $3.7 billion valuation.10 It closed with more money and a higher price.18 In a market where many companies settle for less than they first sought, that suggests demand for the deal exceeded supply.

The valuation math

EliseAI said it passed $200 million in annual recurring revenue in June 2026, after doubling revenue every year for five straight years.15 On those figures the round values the company at about 20 times ARR. Tech Funding News treated that as an upper bound, because the revenue figure is several months old and the current multiple is probably lower.18 Private-market tracker Multiples.vc lists the round as a Series F. It records the 2025 round at about 22 times revenue and the 2024 unicorn round at about 10 times.5

On this reading, the valuation rose roughly in line with revenue. The multiple did not expand. Most of the jump from $2.2 billion to $4 billion reflects revenue doubling again, not investors paying a higher price for each dollar of revenue. Song said much the same, crediting execution, more products and deeper market penetration rather than any single catalyst.1 One analysis still pointed out that a multiple this high leaves no room for growth to slow. It argued that the new agentic product and the healthcare business need to produce meaningful ARR within the next 12 to 18 months.11

Some caution is warranted. One analysis noted that the ARR figure is self-reported, that the "one in six apartments" claim is never defined, and that the announcement gave no data on accuracy, error rates or customer churn.15 These caveats do not undermine the round, but they are reasons to treat the company's metrics as claims rather than audited results.

From $1 billion to $4 billion in about two years

EliseAI first reached a $1 billion valuation with a $75 million Series D in August 2024, led by Sapphire Ventures.18 The $250 million Series E a year later doubled that, and Reuters reported at the time that investors wanted "vertical AI" companies that build tools for one industry rather than general-purpose models.3 The latest round nearly doubles the price again. That makes three rounds in roughly two years, each larger than the last. Multiples.vc puts total funding at about $742 million across seven rounds.5

The company was founded in 2017 as MeetElise by Song and Tony Stoyanov, who is now chief technology officer. Neither founder came from real estate.18 Before building the product, Song worked as an administrative assistant at a New York residential real estate firm. There she saw property managers fall behind on rental inquiries and miss calls.19

What the business actually does

In housing, EliseAI's software covers the whole renter lifecycle: leasing, resident services, maintenance, billing and renewals.17 The company says it now powers about one in six U.S. apartments and that more than 30 million Americans have used its products.2 It also reports handling about 5 million calls a month.18 One industry newsletter reported more than 6.5 million units on the platform and said EliseAI is building its own property management system. If that happens, EliseAI would move from working inside incumbent software to competing with it directly.

This shift is important because, as Tech Funding News noted, EliseAI has so far run inside systems from vendors such as Yardi, RealPage and AppFolio. That has made it dependent on platforms it does not control.18 Building a property management system of its own would reduce that dependence, though it would also put EliseAI in competition with some of its integration partners.

In early September the company launched Apollo, which it calls an agentic AI teammate. Apollo works inside the systems property teams already use and completes tasks end to end instead of handing them back to staff.2 EliseAI started its healthcare business in 2023, selling to specialty physician groups. Its software automates inbound calls, referrals, scheduling, insurance verification and chart preparation.18 One report said more than 3,500 healthcare organizations use it.13 The company is also testing new voice capabilities with OpenAI.18

The new money will fund product development, larger engineering, deployment and sales teams across North America, and a second engineering hub in San Francisco.17 The New York headquarters is a 109,000-square-foot office in the former Tiffany & Co. building on Fifth Avenue.1

The wider funding picture

The round stands out in a proptech funding market that has become selective. According to a Creti report cited by Yahoo Finance, global proptech venture funding was $4.53 billion across 231 deals in the first half of 2026. That is roughly flat from a year earlier and about 65% below the 2021–2022 peak.2 Eleven rounds of $100 million or more took about half of that capital. EliseAI's single round equals nearly 8% of the first-half total.2

The pattern is clear: investors are putting large amounts into a few scaled AI platforms and less into early-stage companies.2 Analysts at Dakota described the round as part of a second wave of AI investment. The first wave went to model builders such as OpenAI and Anthropic. The second is going to application companies that have turned AI into steady revenue within a single industry.11 Axios put it more simply: investors keep funding AI that automates work in regulated industries.14

The risks

The risks are concrete. Multifamily demand depends on interest rates and occupancy. Healthcare brings long procurement cycles, compliance requirements and difficult integrations with electronic health records.11 Competition is also growing. Property-software incumbents are adding AI features, and AI-native rivals such as Funnel Leasing and Colleen AI target overlapping workflows. EliseAI's own research found that 76% of multifamily operators use more than one AI vendor.11

On balance, the reporting supports a positive view. A fully primary round that came in above its earlier target, with returning lead investors and a new pension backer, does not look like a bubble price. It looks like investors paying for revenue that has already doubled five years in a row. The real test is whether Apollo and the healthcare business can keep that pace now that the valuation leaves little room for a slowdown.
