Brook.ai Secures $28 Million in Series B Funding, Led by UMass Memorial Health and Morningside, to Accelerate Next Phase of Growth and Innovation in Remote Care

SEATTLE, Oct. 16, 2025 /PRNewswire/ -- Brook.ai is making remote care an integral part of U.S. healthcare, extending continuity of care outside the traditional practice setting and delivering measurable improvements in patient outcomes. The company's success has prompted new investment led by UMass Memorial Health and Morningside, accelerating Brook's national expansion through a $28 million Series B to further its equitable, accessible care model.

"At UMass Memorial, we've seen firsthand how Brook's remote care model improves patient outcomes and supports population health. That's why we're proud to lead this investment and expand our use of the platform, helping scale a solution that delivers continuous care at a critical moment for health systems," said Eric Dickson, MD, President and CEO, UMass Memorial Health. "Our goal is to back models that expand access, improve equity, and strengthen the sustainability of care for our patients and community."

Brook has achieved positive health outcomes with its partners, including reducing congestive heart failure (CHF) readmissions by 90% and achieving an 80% increase in controlled populations with hypertension in as little as six weeks.

This investment in Brook comes at a pivotal time as the company experiences significant growth. Always-on, personalized care with Brook's platform has driven increased patient satisfaction and strong patient engagement— reflected in an 82% retention rate and Net Promoter Score of 66, placing Brook in the "excellent" category — and has fueled 204% patient growth over the past year, underscoring its growing value to patients and providers nationwide.

"Outcomes-focused support makes a real difference for patients and providers, and what really sets Brook apart is that people actually use our platform at home, every day. That engagement drives better outcomes and growth, as shown by the ongoing expansion we see with our customers and investors," said Oren Nissim, CEO, Brook.ai. "Our partnership with UMass Memorial and Morningside in our latest investment round allows us to expand our outcomes-driven model to more health systems at a moment when it's needed most."

"Brook's ability to deliver robust clinical outcomes while also creating clear benefits to its health system partners has created a truly differentiated platform, and we are proud to be co-leading with UMass Memorial on this investment," said Stephen Bruso of Morningside. "This round will enable Brook to continue scaling its commercial activities while also expanding its clinical reach to become even more impactful to our partners."

Brook's remote care solution comes at a critical time for healthcare providers, as reimbursement models and care-at-home adoption accelerate toward 2026. It addresses urgent system-wide challenges, including workforce shortages, rising chronic disease, and mounting costs — by delivering outcomes-driven remote care that health systems can implement quickly.

"Our solution addresses the key barriers to adoption, allowing providers to implement remote care without the burden of building infrastructure, hiring staff, or managing complex billing processes," added Nissim.

Brook's platform is designed for easy adoption — health systems can be up and running in 30 days, with no capital expenditure required.

The Series B funding will be used to:

• Expand services for additional patient populations and conditions
• Increase product and engineering headcount, with a focus on safe AI development
• Product enhancements to support higher engagement and better outcomes
• Expand operations to support growth
