W2E is a "legal-tech" consultancy house for architecting and renewing customers' digital identity, access and authorisation solutions with latest IdM technologies - OpenID Connect, OAuth2, self-sovereign identity solutions. Our founders and recruits have typically 20-25 years of experience in software architecting, system design and development with privacy-enhancing technologies (PETs) such as PKI and encryption. As a concrete software product,W2E provides a transparent, privacy-preserving authorisation service for wearable vendors' data APIs. Our SaaS product is an API the customer integrates with. Why would such API be commercially necessary? After 10 years of growing device market, wearable vendors on the consumer market provide their data in varying formats, and each API requires one-to-one plumbing for getting user-authorised access to data. This makes software integrations a costly element over time. With W2E as a multi-API "proxy" the customer needs just a single API integration and is provided with a modern, scalable API with notification support. Activity and vital signs information is served out in HL7 FHIR format - converted from the proprietary data formats of the vendors.
