Sibel Health: $30 Million (Series C) Secured By Northwestern University Spinout For Advanced Monitoring Solutions For Patients

By Amit Chowdhry • Mar 21, 2025

Sibel Health, a medical technology spinout of Northwestern University, announced the closing of $30 million in new equity financing and its 7th FDA 510(k) clearance. The equity funding was led by Sibel’s existing investors, the Steele Foundation for Hope and Dräger, to accelerate the commercial deployment of the ANNE One monitoring platform.

The Steele Foundation for Hope previously led Sibel’s Series B funding round, adding $20 million investment. And Dräger, an international medical and safety technology leader, previously led Sibel’s Series A round, contributing $10 million more in funding.

Enabled by advanced clinical-grade wearable sensors, the ANNE One platform provides wireless monitoring of all vital signs for patients 12 years and older. This funding is timed to Sibel’s newest FDA 510(k) clearance, which enables alarms and alerts along with a powerful central station.

Last year, Sibel Health was awarded a $17.5 million award grant from the Gates Foundation. Sibel Health and Dräger Denmark were recently selected by the Capital Region of Denmark to provide continuous wireless monitoring in multiple Copenhagen area hospitals. This month, Sibel Health also announced that Northwestern Medicine has acquired ANNE One systems to evaluate improvements to nursing workflow and patient sleep quality with wireless sensors.

KEY QUOTES:

“Given the very challenging financing environment, we are ecstatic to see our existing investors fund our entire round given their confidence in our product roadmap and growth trajectory.”

“Without interoperability of medical devices, particularly vital signs monitors like ours, we cannot capture the broader care context and realize the full potential of AI to detect patient deterioration earlier.”

– Steve Xu MD, cofounder and CEO of Sibel Health

“We are especially proud of the fact that our sensors are FDA-cleared under the IEEE SDC 11073 standard, which supports open and secure communication between medical devices, replacing traditional proprietary networks. Interoperability is the future, and our hospital partners are increasingly demanding it.”

– Jong Yoon Lee, CTO and co-founder of Sibel Health

“We are pleased to further strengthen the cooperation between Dräger and Sibel through this investment. The possibility to integrate wireless, wearable sensors into the digital acute care ecosystem via the new connectivity standard ISO/IEEE 11073 SDC is an important milestone towards the future of patient monitoring along the entire patient care journey.”

– Toni Schrofner, Chief Officer of the Medical Division at Dräger and Sibel board member
