Inogen Inc

Founded in 2001 and headquartered in Goleta, California, Inogen develops and manufactures portable oxygen concentrators and respiratory health products for patients requiring long-term supplemental oxygen therapy. The company's primary offerings include the Inogen One and Inogen Rove lines of portable oxygen concentrators designed for ambulatory use, the Rove 4 model, stationary Inogen At Home concentrators, the Simeox airway clearance system, and related accessories including batteries. These devices serve patients with chronic respiratory conditions across the United States and international markets.

The company operates through a dual revenue model combining product sales with a direct-to-patient rental business. Inogen manufactures and sells its respiratory devices through distribution channels while also renting products directly to end users, creating recurring revenue opportunities. The company competes in the portable oxygen concentrator segment, where product portability, battery life, and noise level are key differentiating factors.

With a market capitalization of approximately $0.2 billion, Inogen operates as a mid-sized medical device manufacturer with global distribution. The company serves a patient population dependent on supplemental oxygen therapy, a market driven by aging demographics and the prevalence of chronic obstructive pulmonary disease and other respiratory conditions.
