What WeFitter does
WeFitter is a Netherlands-based B2B API platform that enables digital health, fitness, corporate wellbeing, e-health, and insurance companies to integrate 300+ wearable and fitness app data sources, gamification features, and AI-powered health insights through a single REST API. Founded around 2015 and headquartered in Groningen, the company operates under the legal entity E-Vitality B.V. as a product within Phaitality, a Dutch AI/ML firm focused on preventive healthcare. Core technology combines a Connections API aggregating and deduplicating health data from Apple HealthKit, Samsung Health, Garmin, Fitbit, Google Fit, Strava, Oura, Whoop, Polar, Huawei Health, and others; a Gamification engine supporting individual, team, global, goal, streak, and leaderboard challenges with badges, levels, and point models; an AI module delivering individual profiling, personalized recommendations, and a Bio Age score developed with Amsterdam UMC; and an administrative Dashboard for configuration. The architecture is REST-based with webhooks and event endpoints for integration, and includes mobile SDKs and a self-serve developer portal.
WeFitter monetizes through subscription-based API licensing and tiered onboarding services (Basic and Premium packages), with quote-based enterprise pricing and multi-year contracts. Go-to-market combines a self-serve developer portal targeting SMBs and individual developers with direct enterprise field sales, supported by content marketing (blog, whitepapers), industry events (FIBO, 4YFN), partner referrals, and a partner ecosystem. The company maintains ISO 27001, NEN, and GDPR certifications, with data processing agreements and EU regulatory compliance serving as trust signals in regulated healthcare and insurance markets.
The customer base spans corporate wellbeing, digital fitness, e-health, and insurance segments and includes Bupa, Sanitas (Bupa subsidiary serving ~2M customers across 5 hospitals and 20+ health centers), Champ, MyVitale, HealthBlocks, Abel Health, and 123habit. WeFitter is active in 30+ countries with 4+ focus markets, and reports aggregated platform scale of 16.3 billion steps, 6.5 billion kcal, and 7.6 billion km of distance tracked. Notable non-traditional deployments include a Web3 live-to-earn partnership with HealthBlocks and a tripartite corporate wellbeing initiative with 123habit and Dutch pension administrator PGGM&Co targeting healthcare workers.
