Ambrosia Systems

Ambrosia Systems and the RIZZ non-invasive monitoring ring

Ambrosia Systems, Inc. is a medical technology company founded in San Francisco in 2016. Its work focuses on developing continuous glucose monitoring (CGM) and metabolic wellness devices and platforms. Its most recent product, RIZZ, is presented as the world's first non-invasive CGM ring: a single device that tracks glucose, sleep, stress, heart health, activity, oxygen levels, and skin temperature without pricks or adhesive sensors, delivering real-time insights.

Products and platform

The company's catalog combines hardware and monitoring apps:

• RIZZ: a non-invasive smart CGM ring that adds general wellness and metabolic health metrics. The company describes it as a premium device aimed at glucose optimization and physical recovery.
• BluCon: an affordable clinical-grade CGM device for insulin-dependent users.
• LinkBluCon App: a monitoring app compatible with FreeStyle Libre 2 Plus and Libre 3 Plus sensors. It is offered via annual or monthly subscription.
• NightRider BluCon: a component of the BluCon ecosystem for overnight glucose readings.

The platform supports multiple CGM systems, including FreeStyle Libre and Dexcom, and is sold with subscription options. The site also mentions a developer API.

Comparison with other wearables

The company publishes a comparison between RIZZ and the Oura Ring and WHOOP rings. According to that table, RIZZ is the only one of the three that includes non-invasive real-time glucose tracking, food insights, recovery and sleep score, continuous AI-driven stress index, activity and calorie tracking with metabolic data, and temperature, SpO₂, and heart rate measurement. Oura Ring and WHOOP are marked as lacking glucose tracking and food insights. The comparison also notes that RIZZ does not require a mandatory subscription, while the other two do, and that its primary focus is general wellness, metabolic wellness, glucose optimization, and fitness recovery, compared with Oura's general wellness and WHOOP's fitness recovery. In terms of form factor, RIZZ and Oura Ring are smart rings, while WHOOP is a wrist band.

Target audience

The device targets five profiles: health and wellness enthusiasts; individuals focused on metabolic health; professionals seeking work-life balance; athletes and fitness lovers; and people looking to monitor glucose without pricks or sensors. The company also mentions healthcare providers, patients, payers, app developers, and employers among its users, and offers a demo through a contact form that asks for the interested party's role.
