EliseAI has raised $350 million in a fresh funding round that values the New York-based artificial intelligence company at $4 billion, a major increase from its $2.2 billion valuation about a year ago.
The September 29, 2026 funding round was led by Andreessen Horowitz, known as a16z, and Bessemer Venture Partners. Ontario Teachers’ Pension Plan joined as a new investor, while Sapphire Ventures and Navitas Capital, which previously backed the company, also participated. Fortune reported the financing is entirely primary capital, according to CEO Minna Song.
The new capital will support product development and help EliseAI expand its engineering, deployment and sales teams across North America. The company also plans to establish San Francisco as a second engineering hub alongside its New York headquarters.
The latest funding comes as investors continue to back AI businesses solving specific problems for established industries.
EliseAI has built a strong position in housing. Its technology automates activities such as leasing enquiries, resident communication, maintenance requests and lease renewals. The company has also expanded into healthcare, where its tools handle administrative processes including patient intake, appointment scheduling, insurance checks, referrals and follow-up.
The company said its platform now powers about one in six apartments in the United States, while more than 30 million Americans have interacted with EliseAI since it was founded. In June, EliseAI announced that it had crossed $200 million in annual recurring revenue, after recording five straight years of year-over-year revenue doubling.
That revenue milestone helps explain the stronger valuation. EliseAI is positioning AI as technology embedded in the daily operations of housing providers and healthcare organisations.

EliseAI Expands AI Automation Across Housing and Healthcare
Earlier in September, EliseAI introduced Apollo, an agentic AI product designed to carry out tasks across its platform. Instead of functioning only as a chatbot, Apollo is designed to work inside existing workflows and complete tasks according to each user’s permissions.
According to the company, Apollo can support activities across leasing, maintenance and property operations. EliseAI has also said that decisions requiring human judgement, including approving or denying applications and signing off on lease terms, remain with people.
This reflects a broader shift in enterprise AI. Businesses are increasingly moving from tools that generate text or answer questions towards systems capable of completing defined workflows. For EliseAI, that creates room to deepen its role in industries where administrative work consumes valuable staff time.
The company’s financial story has also changed quickly. EliseAI raised $250 million in its Series E round in August 2025 at a valuation of $2.2 billion. Before that, it raised $75 million in Series D funding in 2024, when its valuation reached $1 billion.
Why the New EliseAI Funding Matters
The latest $4 billion valuation also highlights the rise of vertical AI, where products are built around specialised workflows, regulations and operating needs within an industry.
For African businesses watching the global AI market, the EliseAI story offers a practical example of how automation can grow from an ordinary operational problem into a wider technology platform. Similar opportunities exist in customer service, healthcare administration, property management, finance and other sectors where repetitive processes consume time and money.
EliseAI’s approach is different from the race to build broad consumer AI assistants. The company has concentrated on areas where businesses already have large administrative workloads and where improvements can be tied to specific operational outcomes.
That focus has helped the startup build a customer base around housing and healthcare while expanding the number of tasks its AI systems can handle. Its latest fundraising shows that investors are continuing to place significant capital behind companies that combine artificial intelligence with specialised business processes.
With the new funds, EliseAI can increase its workforce, develop additional products and expand its engineering presence. The San Francisco hub will complement its New York headquarters as the company continues its next stage of expansion.
Back Story: How EliseAI Moved From Property Management to a $4 Billion AI Company
EliseAI was founded in 2017 by Minna Song and Tony Stoyanov. The idea grew from Song’s experience working as an administrative assistant at a residential real estate firm in New York, where she saw how much time property teams spent handling repetitive communication with tenants and prospective renters.
TechCrunch reported in 2024 that the founders began building AI software to automate those communications. EliseAI initially focused on housing, using AI to manage messages, calls, apartment tours, maintenance requests, lease renewals and related tasks.
The company later expanded into healthcare, applying a similar automation approach to administrative work in medical practices. Its development from a focused property management tool into a broader housing and healthcare AI platform has now produced another major funding milestone.
With $350 million in fresh capital and a $4 billion valuation, EliseAI is moving into its next phase with more customers, broader AI products and plans for a larger engineering footprint. The company will now have to turn that expansion into sustained growth while showing that AI can reliably handle increasingly important business operations.
