Read full description
Inogen's business model is based on a direct-to-consumer sales and rental model, which allows the company to bypass traditional durable medical equipment providers and build relationships directly with patients. The company also sells its products through a network of distributors and home medical equipment providers.
Inogen operates in the home medical equipment market, which is a large and growing market driven by the aging population and the increasing prevalence of chronic respiratory diseases. The company's target customers are patients with chronic obstructive pulmonary disease (COPD) and other respiratory conditions that require long-term oxygen therapy.
