RJ-LASER

What RJ-LASER does

RJ-LASER (legal entity Reimers & Janssen GmbH) is a German medical device manufacturer founded in 1982 in Waldkirch, Germany, specializing in therapeutic laser systems for non-invasive pain treatment and tissue stimulation. The company operates from two locations — a Waldkirch headquarters and a Berlin office handling sales, manufacturing, development, purchasing, and service — and employs between 1-10 people. Its three core product lines are: (1) the LaserPen, a portable spot laser originally developed in 1985 and still in production 35+ years later; (2) the Physiolaser, a modular Class 3B system with plug-and-play interchangeable probes (Single Probe, LightNeedle with 90-degree beam-deflecting micromirrors, and Cluster Probes for joint and area therapy); and (3) the LightStream, a high-end Class 4 system launched in 2017 featuring a Base Station with an indications library for personalized treatment plans, a 1.5-15W HighPower Laser, Bluetooth connectivity, touchscreen, and a mobile app for remote maintenance and anonymized treatment data collection. All products are EU MDR 2017/745 certified and ISO 13485 compliant, with each device hand-assembled and tested in Germany before shipment.

The company's revenue model is primarily hardware sales of Class 3B and Class 4 medical laser devices through direct inquiry-based sales and a network of 20+ international distributors in 40+ countries (including Gold Partners GSDtec in Taiwan and Karl Blum in Germany). Secondary revenue streams include professional education seminars through the RJ-Laser Academy (149 EUR per attendee, 9-10 CME credits) and a research data-collection initiative tied to the LightStream system. RJ-LASER targets a horizontal customer base of medical practitioners — primarily general practitioners, orthopedists, pain therapists, and physiotherapists — with additional reach into veterinarians, dentists, and naturopaths, citing a cumulative installed base of more than 10,000 doctors and therapists worldwide. The company is privately held by its founders and management (Josephus Janssen, H. Werner Reimers, and Heiko Sachse), with no disclosed external institutional investors or funding rounds.
