Open Wearables Initiative

What Open Wearables Initiative does

The Open Wearables Initiative (OWEAR) is an industry collaboration founded in 2020 and based in Cambridge, Massachusetts, that operates as an open-source health intelligence platform for digital medicine. Its core function is to serve as a community hub for the indexing, distribution, and formal benchmarking of open-source algorithms that process wearable and sensor-generated health data into validated digital measures. The platform comprises four principal products: a searchable Open Algorithms Database with standardized metadata schemas linking to public source-code repositories (e.g., GitHub, Synapse.org), an Open Data Sets repository including gold-standard datasets for independent algorithm evaluation, an Emerging Standards Program that identifies de facto industry-standard algorithms (GGIR being the inaugural catalog with 300+ published references), and an Algorithm Benchmarking program covering gait and sleep measurement in its Phase One pilots. A unified API connects major wearable providers, and sleep/resilience scoring algorithms are MIT-licensed at no per-user fee.

Technically, OWEAR does not build the underlying algorithms but curates, benchmarks, and standardizes them through community contribution and neutral evaluation. The platform architecture rests on three functions: (1) a community hub for digital health algorithms with a standard metadata schema for discovery; (2) a community hub for digital health data with transparency-promoting open datasets; and (3) a formal benchmarking program where performance metrics are publicly exposed for all submissions — even proprietary ones — and evaluation queues remain open for continuous head-to-head comparison. The OWEAR co-founder Geoffrey Gill is also President of Shimmer Americas, providing a foundational link to wearable sensing technology and donated staff time for catalog maintenance.

The business model is non-commercial by design. OWEAR is MIT-licensed with no per-user fees at any scale, and revenue is explicitly not the primary objective. The initiative is sustained through in-kind contributions from member organizations — particularly Shimmer Research — and through the voluntary participation of pharmaceutical companies (Johnson & Johnson, Pfizer, Eli Lilly, Merck, Novartis), research institutions (Sage Bionetworks, CTTI), technology providers, and standards bodies (IEEE). Its go-to-market is community-led and event-driven, relying on industry conference presentations (e.g., DPHARM), PR through healthcare media, a direct-access website (owear.org), and grassroots developer relations via public repositories. Customer segments include clinical research organizations and pharma companies seeking validated digital endpoints for trials, academic researchers, clinicians needing transparent and verifiable algorithms, and digital health developers building on the unified wearable API.

Revenue model

1. Open-Source Platform Access: The platform operates as a free, open-source resource with MIT licensing and no per-user fees at any scale. Revenue is not the primary objective; instead, OWEAR serves as a collaborative initiative to promote digital medicine through open sharing of algorithms and datasets.
2. Industry Collaboration Services: OWEAR operates as a collaboration platform without direct monetization. The initiative is sustained through member contributions, donations of time and resources from founding organizations like Shimmer Research, and industry participation.
