Summary: Sibel Health secured $30 million in funding and its seventh FDA 510(k) clearance for the interoperable ANNE One vital-sign monitoring platform, accelerating its adoption in hospitals.
Key Takeaways:
- Sibel Health closes a new $30 million dollar Series C financing round led by the Steele Foundation for Hope with significant participation by Dräger.
- New FDA 510(k) clearance positions Sibel for commercial expansion in medical monitoring.
- Northwestern Medicine purchases Sibel systems to evaluate nurse workflow improvements and patient sleep quality with wireless wearable sensors.
Sibel Health has closed $30 million in new equity financing and achieved its seventh US Food and Drug Administration (FDA) 510(k) clearance. The equity financing was led by Sibel’s existing investors, the Steele Foundation for Hope and Dräger, to accelerate commercial deployment of the ANNE One monitoring platform.
“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,” says Steve Xu, MD, cofounder and CEO of Sibel Health, in a release. The Steele Foundation for Hope previously led Sibel’s Series B round, adding an additional $20 million investment. Medical and safety technology company Dräger previously led Sibel’s Series A round, contributing $10 million more in funding.
Enabled by wearable sensors, the ANNE One platform offers wireless monitoring of all vital signs for patients 12 years and older.
This financing is timed to Sibel’s newest FDA 510(k) clearance enabling alarms and alerts along with a central station.
“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,” notes Jong Yoon Lee, CTO and cofounder of Sibel Health, in a release.
“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,” adds Xu.
Toni Schrofner, chief officer medical division at Dräger and Sibel board member, says in a release, “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.
In early 2024, Sibel Health was awarded a $17.5 million dollar award grant from the Gates Foundation. Later in 2024, Sibel Health and Dräger Denmark was selected by the Capital Region of Denmark to provide continuous wireless monitoring in multiple Copenhagen area hospitals.
In March of 2025, Sibel Health, a spinout of Northwestern University, is proud to also announce that Northwestern Medicine has acquired ANNE One systems to evaluate improvements to both nursing workflow and patient sleep quality with wireless sensors.
