Nanosensors Startups funded by Y Combinator (YC) 2026

We are developing a new paradigm for consumer health tech wearables by replacing a 100lb optical instrument with an area of silicon smaller than a postage stamp.

Vena Vitals makes a small sticker that monitors blood pressure continuously. We've shown that it works in the operating room and is as accurate as the best tools doctors have today, at a fraction of the cost. We're a team of health tech scientists with multiple past startups and exits, and we've built products that have scaled to over 2M users.
