The Nightscout Foundation

What The Nightscout Foundation does

The Nightscout Foundation is a US-based 501(c)(3) nonprofit organization (Tax EIN 47-2130306), established in 2013 in Littleton, Colorado, that supports open-source diabetes management technology for people with Type 1 Diabetes. It is entirely volunteer-run with no paid staff. The foundation anchors the #WeAreNotWaiting movement and supports four interconnected open-source projects: Nightscout (real-time CGM data monitoring and web visualization), Loop (iOS-based automated insulin delivery), Trio (iOS OS-AID based on OpenAPS), and AndroidAPS (Android artificial pancreas system). These tools collectively form a DIY automated insulin delivery ecosystem that users self-build and operate on their own smartphones, predating commercial equivalents like Omnipod 5.

The foundation's business model is donation-based, with no products sold for profit. Revenue streams include direct donations ($10 to $1,000), monthly recurring subscriptions ($5 to $500/month), HackDiabetes conference sponsorships ($15 to $50,000), merchandise (Sport-Tek shirts at $50, stickers at $10), and affiliate donation programs through Amazon Smile, Brave Rewards, and Bravelets. Go-to-market is community-led through Facebook groups (Looped Group, CGM in the Cloud, Loop and Learn), annual hackathons, and peer-to-peer word-of-mouth among the global T1D community. Hosting costs are estimated at $10 per user per month, suggesting some users directly sponsor their hosted Nightscout instances.

The foundation serves two primary customer segments: individuals living with insulin-dependent Type 1 Diabetes who need continuous glucose monitoring and automated insulin management, and parents/caregivers who require remote monitoring capabilities for children with T1D. A secondary segment comprises DIY diabetes technology developers and volunteer engineers who contribute code, documentation, and hackathon projects. The foundation's value proposition centers on providing free, open-source alternatives to commercial diabetes management systems, emphasizing community-driven innovation, flexible control, and caregiver peace of mind through real-time remote glucose monitoring.
