BOSTON & TEL AVIV, Israel–(BUSINESS WIRE)–Eleos, the leader in AI for behavioral health, today announced a $60M Series C funding round led by Greenfield Partners, with participation from existing investors such as F-Prime Capital, Eight Roads, Menlo Ventures and ION — and new ones, including the Michael & Susan Dell Foundation, Union Tech Ventures and Centerstone. This round brings Eleos’ total funding to over $120M.

Coming on the heels of its recent Series B, this preemptive round reflects Eleos’ rapid ascent as the most widely deployed enterprise-grade behavioral health AI solution on the market. By going deep into a particular care domain, Eleos has enabled AI Agents to transform care and liberate providers from administrative burdens. The company will use the fresh capital to expand its offerings, grow its commercial team and push into underserved segments of behavioral healthcare — particularly substance use disorder (SUD) treatment centers. Post-acute behavioral healthcare, an $11B market historically underfunded by health tech, is a core focus of Eleos’ growth strategy.

The Series C announcement coincides with the company’s launch of a powerful new clinical documentation improvement (CDI) product, Eleos Compliance. Developed with guidance from legal and regulatory experts retained by the National Council for Mental Wellbeing, Eleos Compliance gives behavioral health organizations near-instant review of every submitted progress note. Leveraging agentic AI — the next generation of AI that proactively surfaces insights — Eleos Compliance flags potential documentation errors before they can trigger costly fines or payment clawbacks. This proactive approach simplifies the appeals process and supports ongoing accreditation efforts.

“From day one, Eleos has been committed to empowering clinicians — not replacing them — and expanding their capacity,” said Alon Joffe, Co-Founder and CEO of Eleos. “By building on our agents for clinical documentation and patient engagement, our new Compliance product is the next step in our mission to free up clinicians’ time and energy to focus on care rather than administrative bottlenecks. With this round of funding, we’re doubling down on the development of intelligent AI systems that drive efficiency and help providers capture the revenue they need to thrive and reach more people in need.”

Eleos tripled its annual revenue over each of its first three years in business, doubling its revenue in 2024. With more than 120 customer organizations in over 30 states across the U.S., Eleos is the most-deployed AI platform in behavioral health today. The investment from Greenfield will fuel expansion of Eleos’ product offerings and market penetration. Eleos also plans to add more senior leaders and more data and engineering talent on the back of this latest funding round.

“We’re proud to back the phenomenal team at Eleos as they revolutionize the behavioral health space — a market of immense importance and scale which is facing severe challenges,” said Shay Grinfeld, Managing Partner at Greenfield Partners. “Their transformative product alleviates the overwhelming administrative burden faced by providers, empowering them to focus on delivering exceptional care. Eleos’ innovative use of AI is reshaping the way behavioral healthcare is provided, and we are excited to be part of their journey.”

Eleos uses the largest dataset of real-world treatment sessions to power proprietary behavioral health AI technology and is the first behavioral healthcare company to leverage multimodal large language models (MM-LLMs) to process multiple data input types simultaneously. A recent randomized controlled trial (RCT) found Eleos improved progress note submission times by more than 80% while doubling client engagement and improving care outcomes by a factor of 3-4x when compared to treatment as usual (TAU).

“Eleos has been exceptional in supporting our team since day one,” said Prasad Kodali, Chief Information Officer at Centerstone, a multistate nonprofit health system specializing in mental health and substance use disorder treatments. “They’re in a league of their own compared to other tech vendors I’ve encountered. Their focus goes beyond just providing a great product — they’re deeply committed to making sure the users of their platform are happy. It’s clear that they’ve built their solution with the end user’s needs at the forefront, and their care for the experience they deliver is extraordinary.”

On February 19, 2025, Eleos will host a webinar presenting a detailed overview of Eleos Compliance as well as other product enhancements. Learn more and sign up here to register: New Year, New AI Advancements with Eleos Documentation and Compliance.
