EliseAI, the New York–based AI company focused on automating complex workflows in healthcare and housing, has raised $250 million in a Series E round. The funding was led by Andreessen Horowitz (a16z), with participation from new investor Bessemer Venture Partners and existing backers Sapphire Ventures and Navitas Capital.
With this new capital, the company plans to expand its team across engineering, customer experience, sales, marketing, and strategy and operations. EliseAI is also growing its office hubs in New York, San Francisco, Boston, and Chicago.
Founded in 2017 by CEO Minna Song and CTO Tony Stoyanov, EliseAI began in the housing sector. Song, who studied computer science at MIT, worked as an administrative assistant at a New York real estate firm after college to better understand the industry’s challenges. There, she saw firsthand the inefficiencies in tenant communication and leasing.
The company’s early focus on automating property management tasks gained traction, and today EliseAI supports more than 600 owners and operators, including 75% of NMHC’s Top 50 Operators. Its technology powers automation for one in eight apartments in the United States, handling leasing inquiries, maintenance requests, tenant communications, and more. Clients include large operators such as Zillow Group.
In 2022, EliseAI expanded into healthcare, applying its AI platform to outpatient specialties such as dermatology and women’s health, where administrative costs and manual workflows remain a major burden. By integrating with electronic health record (EHR) systems, the company helps providers automate appointment scheduling, patient communication, and compliance tasks.
“Our mission is built on the belief that AI can dramatically improve how critical industries operate,” said Minna Song, co-founder and CEO of EliseAI. “For an average American, healthcare and housing represent approximately 40% of household spending. These two systems are notoriously complex, outdated, and painful to navigate. And we’re here to fix it with agentic AI. We’re excited to partner with both new and returning investors to supercharge our growth and accelerate solutions that reduce costs and increase efficiency in the industries that matter most.”
Since its $75 million Series D in August 2024, EliseAI has grown from 150 to over 300 employees and surpassed $100 million in Annual Recurring Revenue (ARR). The company has also launched new AI-powered products for both verticals.
In healthcare, EliseAI targets front-desk and call center operations, which contribute significantly to the U.S.’s more than $600 billion in annual administrative costs. Its automation platform streamlines scheduling, prior authorizations, and patient communication, with the company claiming it can cut overhead by up to 25%, reduce wait times, and lower call abandonment rates.
“EliseAI has transformed our OB GYN call center operations by streamlining complex workflows, reducing patient wait times, improving operational efficiency, and elevating the customer experience,” said Dr. Pierre Hage of Women’s Health CT – Obstetrics & Gynecology. “With EliseAI, we’re on the path to achieving 24/7/365 comprehensive practice management for our patients and staff.”
In housing, EliseAI continues to address labor shortages and high turnover which can exceed 40% annually in the sector with tools such as AI-Guided Tours, Lease Audits, a Fee Transparency Suite, and a Maintenance App. These products enable property managers to improve efficiency and resident experiences at scale.
“Customers consistently describe EliseAI as the most exciting software solution in the industry,” said Alex Immerman, partner at a16z Growth. “The company already powers 10% of the U.S. apartment market today, with a massive opportunity still ahead of them domestically and abroad as they begin to enter international markets. We’re thrilled to be leading Elise’s latest financing as they raise the standard for how people experience two of life’s most essential services: housing and healthcare.”
EliseAI’s strength lies in building deeply integrated vertical solutions rather than horizontal products. “The difference with EliseAI is that we’re a vertical AI company, not a horizontal one,” she explained in a podcast interview. “Horizontal companies solve one sliver of a problem across industries. Our approach is to go ten layers deep into every problem, so we can actually solve it end to end.”
She stressed that true impact requires reliability and integration into the physical world. “If you report a broken sink, a typical AI might just submit a ticket. Our AI goes further: it coordinates the workforce, manages resources, integrates with compliance systems, and ensures the problem is fixed. Sometimes that even means unlocking doors to let people in.”
Song noted that growth has been hard-won in industries slow to adopt new technology. “There’s no ‘app store’ to go viral on in property management. Growth has been blood, sweat, and tears: outbound sales and a lot of work. But we’ve also built strong partnerships,” she said. “Now, if a company offers marketing software or insurance products, they can plug into EliseAI and our system will deliver it directly to residents and customers.”
