Gaining Momentum

Tozuda is a legitimate hardware startup (est. 2014) offering a patented, mechanical head impact indicator. While the technology has high real-world utility for safety and has secured >$500k in funding and B2B pilots, the submission's claim that "most people have used my product" is a significant exaggeration. The project fits the 'Small but promising' calibration tier (100-250) due to verified product existence and funding, despite the low-quality submission and niche actual traction.

Description
Tozuda's Head Impact Indicator is a device that indicates when a hit may cause a head injury with a simple change in color. Our patented technology attaches to the back of your favorite helmet or hardhat. The chamber will change colors from clear to red when a user gets hit at a dangerous acceleration. It's so simple to use, all you have to remember is \"If it's RED, check your head!\" What matters most with a head injury is knowing when to act in order to get an evaluation from a licensed medical professional. Tozuda is an objective tool for users to know when to stop their activity and go get checked out or if they are clear to keep riding after a stumble. This is the perfect tool for parents, coaches, individual recreational athletes, and on the Jobsite. We have two settings for youth and adults and this product is available now on our website, www.Tozuda.com
