The company you have never heard of makes the toothpaste, painkillers and vitamins you buy without thinking. Here is how GSK's cast-off brands became a £30 billion bet on self-care.
SaNOtize Research and Development Corp.
SaNOtize Research and Development Corp. is a Vancouver-based pharmaceutical and medical-device company that harnesses nitric oxide (NO), a naturally occurring antimicrobial molecule, to prevent and treat viral, bacterial and fungal infections. Its patented Nitric Oxide Releasing Solution (NORS) platform powers a Nitric Oxide Nasal Spray (NONS) sold internationally under brands including Enovid, VirX and FabiSpray, along with a pipeline addressing COVID-19, respiratory viruses, sinusitis, wound infection and onychomycosis.
Apreo Health
Apreo Health is a clinical-stage medical device company in Menlo Park, California developing the BREATHE Airway Scaffold, a bronchoscopically delivered, self-expanding nitinol implant that relieves lung hyperinflation in patients with severe emphysema. Unlike existing valve and surgical treatments that collapse or remove lung tissue, the scaffold gently tents open damaged airways to release trapped air while sparing healthy tissue, aiming to expand who can be treated. The company raised a $130M Series B in August 2025 to run its pivotal BREATHE-3 trial and prepare for early commercialization.
Samay
Samay (formerly Respira Labs) is a San Francisco Bay Area medtech company building Sylvee, a wearable chest patch that pings the lungs with sound waves and uses AI to detect COPD and predict flare-ups before they turn dangerous. Founded by physician-inventor Dr. Maria Artunduaga, the company turns a $40 acoustic sensor into a continuous, at-home alternative to hospital pulmonary function tests, aiming to catch the invisible early signs of lung disease that standard tools miss.
resbiotic
resbiotic is a physician-founded microbiome health company building clinically tested probiotics, prebiotics, postbiotics, and bioactive botanicals around its Gut-X Axis platform - the idea that the gut talks to the rest of the body. Its flagship resB Lung Support is positioned as the first clinically tested probiotic targeting the gut-lung axis for respiratory health. Founded in 2020 by physician-scientist Dr. C. Vivek Lal out of microbiome research at the University of Alabama at Birmingham, the company sells direct-to-consumer and through retail including Walmart and GNC, and has raised roughly $20.6M to date.
