What is the Inogen Founding Story?
The Inogen company history began in 2001, with its founding in Goleta, California. The vision for the Inogen company was sparked by three University of California Santa Barbara students: Alison Bauerlein, Brenton Taylor, and Byron Myers. Their entrepreneurial journey was deeply personal, inspired by Alison Bauerlein's grandmother, Mae Krier, who lived with COPD. Mae's firsthand experiences with the cumbersome nature of traditional oxygen therapy, including heavy tanks and frequent refills, highlighted a significant unmet need in the market for more portable and user-friendly solutions.
Recognizing this gap, the founders set out to develop a revolutionary portable oxygen concentrator. Their initial business model focused on creating a pulse dose oxygen machine that would offer patients greater freedom and independence. This commitment to innovation marked the early development of the Inogen company. The team's technical expertise and entrepreneurial spirit, coupled with a strong personal connection to the problem they aimed to solve, fueled their dedication to this venture.
The Inogen founding story is a testament to identifying a critical market need and developing a solution. The first product, the Inogen One Portable Oxygen Concentrator, launched in 2004, represented a significant leap forward. It offered a battery life of 2 to 3 hours, a substantial improvement over stationary concentrators that relied on continuous wall power. This groundbreaking innovation was recognized early on, with the initial prototype securing first place in a business plan competition hosted by UC Santa Barbara's Technology Management Program. The company's early stages were bolstered by venture capital, with a Series C funding round in 2004 successfully raising $15 million, which was instrumental in driving initial product development and market launch, laying the groundwork for the Inogen company's future growth and expansion.
The Inogen company was founded by three university students motivated by a personal connection to respiratory care needs. Their goal was to create a more portable and convenient oxygen therapy solution.

What Drove the Early Growth of Inogen?
Following the successful introduction of the Inogen One in 2004, the company entered a phase of substantial early growth. This period was characterized by the establishment of its foundational product line and the pioneering of a direct-to-consumer sales approach. The initial Inogen One, though limited in battery duration, represented a significant advancement, offering unprecedented mobility to individuals requiring oxygen therapy compared to traditional stationary units. This early success fueled continuous product development focused on enhancing user experience and portability.
The Inogen One, launched in 2004, marked a critical turning point in portable oxygen therapy. It provided users with a level of freedom previously unavailable with stationary oxygen systems. This innovation laid the groundwork for the company's future trajectory in respiratory care.
Building on the initial success, the Inogen One G2 was introduced as a significant improvement. It increased pulse flow settings from 5 to 6, extended battery life to approximately 8 hours, and achieved reductions in both weight and operational sound levels, enhancing user convenience.
A major milestone in the company's expansion was its Initial Public Offering (IPO) on NASDAQ in 2014, which successfully raised approximately $86 million. This capital provided the necessary resources to scale operations, broaden sales channels, and invest further in research and development initiatives.
The release of the Inogen One G3 in 2012 was another key development, weighing just 4.8 pounds and offering up to 8 hours of battery life, quickly becoming a popular choice. The company also expanded its offerings to include stationary solutions like the Inogen At Home Concentrator.
The direct-to-consumer model historically contributed to higher gross margins and facilitated direct relationships with patients, providing valuable insights into user needs. The company also established an international presence, distributing products in 65 countries through various partnerships.
By the close of 2024, the company reported total revenue between $334.5 million and $335.5 million, representing a 6% increase year-over-year. This growth was largely propelled by robust double-digit expansion in its business-to-business revenue segment, indicating successful market penetration and strategic partnerships.
