What keller medizin-technik gmbh does

Keller Medizin-Technik GmbH is a German specialty medical device distributor founded in 1984 and headquartered in Weinheim, Germany. The company operates as the exclusive German distributor for Grason-Stadler (GSI), complemented by distribution rights for Synapsys, Inventis, Madsen/Otometrics, and Vivosonic. The founder-owned business (Inhaber Ulrich Keller) has operated for over 40 years, serving ENT physicians (HNO-Ärzte), hearing aid acousticians (Hörakustiker), hospitals, clinics, and medical practices primarily in Germany.

The portfolio covers the diagnostic chain in audiology and neuro-otology: audiometers (GSI 18, GSI Pello), tympanometers (GSI TympStar Pro, GSI Allegro, Inventis Timpani), otoacoustic emission systems (GSI Corti, GSI AuderaPro), BERA/AABR newborn hearing screening (GSI Novus), and vestibular diagnostics (Synapsys V-HIT), plus consumables such as Sanibel ear tips, electrodes, batteries, and recording paper. Devices sold by Keller embed manufacturer-developed signal processing logic, including automated Pass/Refer screening algorithms in OAE and AABR systems.

Revenue mechanics are split across three streams: (1) direct enterprise field sales of capital equipment (devices in the €1,000-€2,000+ range), (2) a B2C/B2B e-commerce shop for consumables and accessories starting at roughly €10, and (3) recurring after-sales services covering repair, maintenance, calibration, installation, and remote maintenance across the installed base. Pricing tiers, consumables replenishment, and multi-year service contracts create a mix of episodic hardware revenue and recurring service and consumables revenue, although no financial breakdown is disclosed.
