Enterprise software maker EliseAI, based in New York, has raised $250 million in Series E funding. The funding round was led by Andreessen Horowitz with participation from Bessemer Venture Partners and Sapphire Ventures, pushing its valuation to over $2.2 billion. This doubles its valuation from last year, when it raised $75 million in Series D funding. 

The fresh capital marks a milestone for EliseAI, which has surpassed $100 million in annual recurring revenue (ARR) earlier this year. With the new funding, EliseAI plans to double its 300-person workforce within the next year, adding roles across its offices in New York, San Francisco, Boston, and Chicago.

The capital will fuel product innovation and accelerate growth in both real estate and healthcare verticals. For investors, EliseAI represents the potential of industry-specific AI platforms that solve deep operational challenges rather than relying on broad, general-purpose models.

How was the idea born? 

EliseAI was founded in 2017 by CEO Minna Song, who met the other co-founder, Tony Stoyanov, while they were studying at Cambridge. After graduation, Song was an administrative assistant at a residential real estate firm in New York City. There, she saw the inefficiencies in the rental and leasing industry, especially around messaging current and prospective tenants.

The company first gained traction in the housing industry, tackling persistent communication inefficiencies between property managers and tenants. Its software now supports clients such as Zillow Group and other major rental managers.

Today, EliseAI powers automation for one in eight apartments in the United States, streamlining leasing inquiries, maintenance requests, and tenant communications. The company’s dominance in real estate remains its largest revenue driver, giving it a strong base from which to expand into new sectors.

Expansion into healthcare

In 2022, EliseAI expanded its platform to healthcare, recognising similar challenges in communication and administrative burdens. The company is particularly focused on outpatient specialities, including dermatology and women’s health, where practices face rising operational costs and manual workflows.

By integrating with electronic health record (EHR) systems, EliseAI helps automate appointment scheduling, patient communications, and compliance tasks. This reduces staff workload while improving patient experience. Early traction in healthcare suggests a significant growth opportunity, given the sector’s scale and complexity.

Generative AI integration

EliseAI’s technology has also evolved with the advent of generative AI, enabling it to handle more complex customer inquiries and workflows. By integrating with leading large language models, including those from OpenAI, EliseAI can manage nuanced interactions that previously required human staff.

This integration moves beyond simple chatbot responses to comprehensive workflow automation, bridging customer communication, backend systems, and compliance requirements. The result is an AI-driven solution that transforms customer service from a cost centre into a scalable, efficient operation.

What’s next?

With strong traction in real estate and fast-growing healthcare adoption, EliseAI is positioning itself as a leader in vertical AI. The new funding will allow the company to deepen its real estate presence, expand healthcare offerings, and continue hiring aggressively to support innovation.

As businesses across industries face rising demand for automation, EliseAI’s practical approach has turned it into an essential productivity tool. Rather than experimenting with AI, enterprises are embedding EliseAI’s solutions directly into their core systems to drive efficiency and improve customer experience.
