What Medi GmbH does

medi³ GmbH operates a single-location therapy, sports, and back center at Burgfreiheit 4 in Alfeld (Leine), Lower Saxony, Germany, combining licensed physiotherapy with health-oriented fitness training under one roof. The company was founded in 2009 and is privately held by managing directors Melanie Witteweg and Curd-Werner Kelm, with approximately 45 employees and no disclosed external funding.

The service portfolio spans eight core areas: physiotherapy (manual therapy, PNF, KGG, MTT, medical massage, lymph drainage, CMD, pelvic floor training), medical fitness training on a Milon circuit and Five back-and-joint system, Rehasport and functional training, §20-certified prevention courses covered by statutory health insurers, a Five back-and-joint center, Polar-monitored cardiovascular training, T-RENA/RV-Fit rehabilitation follow-up (as an approved Deutsche Rentenversicherung partner), and BGM/BGF corporate health management. Supporting modules include group courses (Yoga, Tabata, Indoor Cycling, Pilates, fascia), diagnostics via MediMouse and Tanita, and wellness/massage services. The technology stack consists of branded fitness and diagnostic hardware (Milon, Five, CubeSports, Technogym, Polar, MediMouse, Tanita, AernoviR air purification) integrated with manual clinical workflows rather than a software platform.

Revenue is generated through multiple recurring and fee-for-service streams: insurance-billed physiotherapy and Rehasport (gesetzliche and private Krankenversicherung), recurring medical fitness memberships, insurance-covered §20 prevention courses, institutional T-RENA/RV-Fit referrals from Deutsche Rentenversicherung, corporate BGM/BGF contracts (e.g., Weisig Maschinenbau / WEIRO), and self-pay group courses and wellness services. Distribution is entirely physical and local via the Alfeld studio, supplemented by the Hansefit partner network and insurance-driven referral channels; promotional pricing (e.g., 66-day introductory memberships) supports customer acquisition. Marketing relies on the company website, Instagram (@medi3_alfeld), email, local press, community events, and on-site corporate health days.
