Schiller Bikes (Schiller Sports, Inc.) is a Mill Valley, California company that makes the S1-C, a premium human-powered water bike. Built on a corrosion-resistant anodized aluminum catamaran frame with a Gates Carbon Drive belt, a proprietary gearbox and a retractable propeller, the bike lets a rider pedal across lakes, coastlines and open water at over 10 mph. Founded by Jessica Schiller after she became the first person to bicycle across San Francisco Bay in 2013, the company built a small, design-led business around a niche it largely invented: a real cycling experience on the water for fitness, exploration and fun.
Tenon Medical is a Los Gatos, California medical device company that built the Catamaran SI Joint Fusion System, a patented, less-invasive way to fuse the sacroiliac joint with a single titanium implant placed along an inferior-posterior trajectory. Founded in 2012 and public on the Nasdaq since 2022 (TNON), Tenon targets the often-overlooked SI joint, a frequent and hard-to-diagnose source of chronic lower-back pain. In 2025 it expanded into a multi-product sacro-pelvic platform by acquiring the SiVantage SImmetry technology portfolio.
