StrokeDx is a medical device company developing a next-generation, rapid, and portable stroke detection technology that uses small handheld sensors to detect ischemic and hemorrhagic strokes by measuring blood flow in the brain. Their device offers a low-cost alternative to traditional CT and MRI machines, enabling faster stroke triage and treatment initiation. The company combines novel sensor technology with machine learning and AI algorithms to generate predictive imaging of stroke location within minutes. StrokeDx has raised over $7.65 million in capital, has 4 employees, 5 partners, and has published 3 scientific publications. The company is led by co-founders with strong medical and engineering backgrounds and aims to transform stroke care accessibility globally, especially in resource-constrained environments.
