EliseAI Raises $350M at $4B Valuation Doubling in One Year With a16z Backing

TL;DR

• EliseAI has raised $350M in a new funding round valuing the company at $4B, roughly double its $2.2B valuation from just over a year ago.
• The round was led by Andreessen Horowitz (a16z) with participation from existing backers including Bessemer Venture Partners and Sapphire Ventures, bringing total funding to more than $750M.
• The startup plans to use the capital to scale its AI agents for housing and healthcare, expand R&D and compliance infrastructure, and push toward profitability as investors bet big on vertical AI.

A $350M Bet on Applied AI

EliseAI has officially closed one of the largest AI funding rounds of the year. The New York-based company announced on Tuesday that it raised $350M at a $4B valuation, marking a dramatic leap from its $250M Series E in August 2025 which valued it at $2.2B.

The new round was led by Andreessen Horowitz, which also led the company's previous raise. Existing investors including Bessemer Venture Partners, Sapphire Ventures, and Navitas Capital participated, alongside new strategic backers. With the fresh capital, EliseAI's total funding now exceeds $750M since its founding in 2017 by Minna Song and Tony Stoyanov.

In a statement, the company said the round was oversubscribed amid surging demand for its domain-specific AI systems, with revenue more than tripling year-over-year and strong retention from large enterprise clients.

Why a16z Is Doubling Down

For a16z, the decision to lead back-to-back rounds came down to traction and timing. EliseAI has moved beyond pilot-stage AI to become core infrastructure for some of the largest property managers and healthcare providers in the U.S.

The firm's partners pointed to EliseAI's ability to automate high-volume, compliance-sensitive workflows — from answering renter inquiries and scheduling tours to handling patient intake, appointment scheduling, and follow-ups — while integrating directly with property management and electronic health record systems.

Unlike general-purpose chatbots, EliseAI's models are trained for regulated industries where accuracy, auditability, and 24/7 availability matter. Investors see that vertical focus as a moat, especially as landlords and health systems face persistent labor shortages and rising operational costs.

Where The Money Is Going: Housing Meets Healthcare

EliseAI said the $350M will be split across aggressive expansion in its two core verticals.

In housing, the company powers LeasingAI and ResidentAI for operators managing millions of units, including names like Greystar, Bozzuto, and Asset Living. The funding will scale its voice, text, and email agents that handle everything from lead qualification and tour booking to maintenance requests, renewals, and delinquency outreach.

In healthcare, its HealthAI platform has become the fastest-growing segment. The company plans to deepen integrations with major EHRs, expand HIPAA-compliant voice AI for front-office automation, and invest heavily in clinical workflow safety, monitoring, and human-in-the-loop safeguards.

Additional capital is earmarked for doubling its New York headquarters team, growing its engineering and AI research org, and expanding go-to-market teams to serve enterprise health systems and senior living operators.

What The $4B Valuation Signals For The AI Boom

EliseAI's doubling valuation in just one year underscores a major shift in the AI startup boom: money is flowing from foundation models to applied, revenue-generating AI.

While mega-rounds for model labs continue to grab headlines, investors are increasingly rewarding startups with clear ROI, net revenue retention, and deployment at scale. EliseAI claims its AI agents now handle tens of millions of renter and patient interactions per month, reducing response times from days to seconds and cutting front-office costs by up to 40%.

The raise also cements New York as a growing hub for enterprise AI, and puts EliseAI in an elite group of vertical AI unicorns now valued above $3B. Analysts say the company's trajectory will be a test case for whether specialized AI agents can sustain SaaS-like margins while navigating regulation in housing and healthcare.

What's Next

EliseAI says it is not pursuing an IPO imminently, but is focused on a path to profitability and continued product expansion. The company is exploring new use cases in insurance verification, collections, and resident health coordination, and hinted at potential acquisitions to accelerate its healthcare footprint.

With $350M in fresh capital and a $4B valuation, EliseAI now has both the runway and the expectations of a decacorn-in-waiting. The question is no longer whether AI agents work — it's how fast they can take over the front office of every apartment complex and clinic in America.
