Financiers named in the round included TVM Capital Life Science, Yonjin Ventures, SV Health Investors, Ascension Ventures, First Analysis, Blue Heron, and Intersouth Partners.

The company announced an oversubscribed $53 million Series D preferred stock equity financing on September 9, 2024, co-led by TVM Capital Life Science and Yonjin Venture, with participation from existing investors including SV Health Investors, Ascension Ventures, First Analysis, Blue Heron Capital, and Intersouth Partners.

CEO Wendelin Maners highlighted the investment as validation of the RejuvenAir platform's potential in an underserved patient population, noting its unique ability to address the underlying cause of chronic bronchitis, unlike existing drugs or devices. Dr. Marengere emphasized confidence in the team's vision and upcoming pivotal study data, while Dr. Mao noted the technology's significant global impact on chronic bronchitis patients.
