Stacie Arechavala
Stacie Arechavala is a biomedical engineer and the cofounder and CEO of Selera Medical (YC W24), a San Francisco medical device startup she started in 2023 with Kevin Bui after the two met as fellows at Stanford Biodesign. She trained at the University of Miami and Duke, developed cardiovascular devices at Medtronic, and built low-cost devices for underserved communities before turning her attention to heart failure care. Her guiding line: innovation can change the world, but design is what makes it happen.
Shreya Mehta
Shreya Mehta is the President and CEO of Zenflow, a South San Francisco medical device company she co-founded in 2014 out of the Stanford Biodesign Innovation Fellowship. A biomedical engineer and former FDA reviewer, she spent a decade building the Zenflow Spring System, a minimally invasive, reversible implant that props open the urethra to relieve symptoms of benign prostatic hyperplasia (BPH). She started as CTO before stepping into the CEO seat, closed a $24M Series C in November 2024, and helped guide the company to FDA approval.

A mechanical engineer trained at Penn and Stanford, he spent nearly a decade building InterVene, a medical-device startup, before turning his attention in 2020 to a problem hiding in plain sight: the disappearance of clean, accessible public bathrooms. Throne's solar-powered, sensor-equipped units deploy in under two hours, are free to use, and have logged more than a million uses across 20-plus cities. In October 2025 the company raised an initial $15 million Series B led by Brentwood Associates.
