Stacie Ruth left mega conglomerate Philips when she ran into the chance to revolutionize drug delivery via nebulizers, and co-founded AireHealth. Along the way she realized that changing care for patients with respiratory conditions was actually a bigger problem and opportunity. In April she met Nirinjan Yee from Breath Research who had built an AI system that took lung sounds to predict exacerbations. Last week they merged their companies, and I spoke to them about what the new AireHealth will be doing. —Matthew Holt
