ROOK is a business-to-business health data infrastructure company that provides a single API and SDK layer for accessing data generated by wearables and other health data sources. Its flagship product, ROOK Connect, replaces individual per-device integrations with one interface, and the company states it covers 400+ wearables, with API-based and SDK-based sources including Apple Health, Health Connect, Android, Dexcom, Fitbit, Garmin, Oura, Polar, Whoop and Withings. Alongside wearables, the company markets a Lab API, a Medical Device API, a Medical Records API and a Health Monitoring System, positioning the platform as infrastructure for a continuous health record.

A central part of ROOK's offering is data processing: harmonization for comparability, deduplication, standardization to fill gaps, and normalization to unify scales across brands that label equivalent metrics differently (for example, Oura's "total sleep time" versus Garmin's "time in bed"). Additional components include a webhook for real-time updates, a connection page for end-user device linking, a no-code Extraction App, a ready-to-use ROOK App that collects data from SDK-based sources and shares it with a client system via QR code, and ROOK Score, a proprietary 0-100 health score derived from data collected through ROOK Connect. The company states it is HIPAA and GDPR compliant, references FHIR compliance, anonymizes and encrypts health data, and will sign a business associate agreement.

ROOK serves health and wellness apps, insurers, healthcare providers, fitness platforms, corporate wellness programs, gyms and fitness clubs, gaming companies and pharmaceutical clinical trials. Named customers and partners include Trainingym, Gentherm, PEAR Health Labs, NASM, Novos Lab, Physmodo and Advanta Health Solutions.

Founding story

ROOK's founders are biomedical engineers with experience in medical devices and hardware-software integration for fitness, wellness and health applications, some of whom led clinical research teams at Novartis and Roche. The company started as a heart rate monitoring platform for coaches and gyms before concluding that apps needed a better way to connect to health data, which led to the API business.

Business model

B2B SaaS. ROOK sells API and SDK access to health data infrastructure to companies that embed wearable and health data into their own applications, with published pricing tiers and tailored arrangements for large-scale or unique requirements. An investor memo describes the offering as "Health-data-as-a-Service" delivered by API and charged per active user.

Subscription/usage-based access to the API, described by an investor memo as charged per active user; the company publishes a pricing page and offers custom pricing for large-scale deployments.

Traction

The company reports more than 5 million connected devices, roughly 12 months of developer time saved and about 30% engagement lift for customers. Named clients and partners include Trainingym, Gentherm, PEAR Health Labs, NASM, Novos Lab, Physmodo and Advanta Health Solutions, whose CEO credits ROOK with tracking 10x more activity types across data sources. An investor memo written around the pre-seed round stated that the company launched its commercial product in August 2022 after completing Techstars and had grown to an undisclosed level of enterprise contracts, which the investor characterized as the fastest revenue growth it had seen from a seed-stage company.

Latest developments

Following its March 2023 pre-seed round and rebrand, the company expanded its product line beyond the wearable API to include a Lab API, Medical Device API, Medical Records API and a Health Monitoring System, and states coverage of 400+ wearables and more than 5 million connected devices.
