From Lab Idea to Field Revolution

Born from a shared frustration with expensive and inaccessible diagnostics, SpiroFit began as a research initiative between sports scientists and engineers — now trusted by professionals across Europe.

2004

Foundation of Sendsor GmbH

Sendsor GmbH is founded and positioned as a medtech company focused on respiratory health. From the beginning, the mission is clear: to develop diagnostic and therapeutic technologies for real-life applications in pulmonary medicine and provide respiratory competence.

2010

CO₂ Sensor Breakthrough

Additional patents are registered, most notably the core patent for a novel CO₂ sensor. This sensor technology, in its evolved form, becomes a central component of the SpiroFit system.

2024

Second Generation & International Expansion

The second-generation device is introduced. With improved hardware and software, SpiroFit enters new markets across Europe and the U.S., bridging performance analytics and lab-grade precision.

2004

Patent for Flow-Based Spirometer

A patent is filed for a spirometer with a replaceable flow tube. The technology is later adopted and distributed by the medical device company PARI – a milestone in making Sendsor’s innovations clinically relevant.

2017

Market Debut & First Sales

SpiroFit is unveiled at FIBO in Cologne and launched to early adopters. The first generation is distributed to pilot users and later sold in the German-speaking market. Customer feedback plays a key role in improving the product and guiding its roadmap.
