The Ultrasound Machine Wants to Become a Stethoscope
Exo squeezed three ultrasound probes, real-time AI and the paperwork of a hospital imaging program into one pocket-sized system. The harder trick is making bedside scanning routine rather than exceptional.

Us2.ai
Us2.ai is a Singapore-based medtech company that builds FDA-cleared, CE-marked AI software to automate echocardiography (cardiac ultrasound) analysis and reporting. Its vendor-neutral platform - branded the AI Echo Copilot - turns raw DICOM echo studies into fully editable, structured clinical reports in seconds, detecting conditions such as heart failure, aortic stenosis, pulmonary hypertension and cardiac amyloidosis. Founded in 2017 as eko.ai and rebranded to Us2.ai in 2021, the company aims to widen access to expert-level cardiac diagnostics across hospitals, echo labs and clinical-trial core labs worldwide.
Pocus
Pocus is an AI-powered product-led sales and revenue intelligence platform that helps go-to-market teams turn scattered product usage, CRM, and intent data into prioritized action. Founded in 2021 by Alexa Grabell and Isaac Pohl-Zaretsky, the San Francisco company tells sales reps which accounts to work, who to contact, and what to say by surfacing high-intent buying signals and generating AI account plans. Used by product-led companies including Asana, Canva, Miro, Monday.com and LaunchDarkly, Pocus raised $23M in seed and Series A funding backed by a16z and First Round Capital, and was acquired by Apollo.io in March 2026 to power Apollo's AI-native GTM operating system.
Amin Nikoozadeh
Amin Nikoozadeh is the founder and CEO of Vave Health, a San Jose company building affordable, wireless handheld ultrasound. A Stanford-trained electrical engineer who spent years shrinking an entire imaging system onto the tip of a 3mm catheter, he started Vave in 2015 after confronting a stark fact: roughly two-thirds of the world's population has no access to medical imaging. The company's pocket-sized probe earned FDA 510(k) clearance in 2019 and now powers millions of scans across hospitals, medical schools, and underserved clinics.

Patricia "Trish" Henwood, MD, FACEP is an emergency physician who runs quality and safety across an 18-hospital system as Executive Vice President and Chief Clinical Officer of Jefferson Health in Philadelphia. Before the C-suite, she carried a portable ultrasound probe into an Ebola treatment unit in Liberia and built training programs that put imaging in the hands of clinicians in Rwanda, Uganda, Tanzania and beyond. She founded the nonprofit PURE to bring point-of-care ultrasound to resource-limited settings, published her bedside Ebola work in the New England Journal of Medicine, and now applies the same systems thinking to closing care gaps for vulnerable populations at home.
