Chad Andresen on Lunosa’s Injectable Neurostimulator and Lessons from Stimwave

Neural Implant podcast - the people behind Brain-Machine Interface revolutions

In this episode, we sit down with Chad Andresen, Chief Business Officer of Lunosa, to explore a groundbreaking approach to treating obstructive sleep apnea. Lunosa is developing a self-expanding, injectable neurostimulator that aims to replace invasive facial surgeries with a minimally invasive, high-impact solution — tapping into a $10 billion market. Chad also reflects on his time at Stimwave, a pioneering neuromodulation company that saw both innovation and controversy. He shares insights from testifying against Stimwave’s former CEO, lessons learned from the company’s collapse, and how those experiences shape Lunosa’s vision and execution today.

Top 3 Takeaways:

• User feedback can vary drastically by region — while patients in Mexico and Europe reported positive results, U.S. participants were far more critical and vocal, revealing major usability issues that had been previously overlooked.
• A major red flag in a startup is when experienced, well-tempered professionals leave quickly and repeatedly — it often signals deeper cultural or leadership issues that young founders may overlook until it's too late.
• Lunosa developed a novel “nerve net” implant that works like a fishing net—capturing multiple nerve branches responsible for tongue movement in sleep apnea—offering selective stimulation to activate helpful muscles while avoiding unwanted ones.
