Designing a fingerprint-access 9mm pistol from the ground up.

Kai Kloepfer is the founder of Biofire Technologies, a startup building the next generation of the firearm. By incorporating advanced biometric safety technology into a handgun, he hopes to help save thousands of lives a year and disrupt an industry that has lost its drive to innovate. His technology, a smart gun, is a custom handgun incorporating a fingerprint sensor so that only the owner or authorized users can fire the weapon.

He has been working for 4 years to help spread the word about smart guns, and present them as a viable option. This has included feature coverage in the Wall Street Journal, NYT Sunday Edition, CBS Evening News, Vice, and viral videos with 30m+ views. He was also selected as a 2017 Forbes 30 under 30 in Consumer Tech for his work with Biofire.

Nobody has made the gun world’s Tesla, at least not yet. For the mindset that requires, a teenager might just be the man for the job.

Kai’s work started with a high school science fair project, which went on to become the top engineering project by an American student at the 2013 Intel International Science and Engineering Fair. Kai’s biometric technology placed him in a group of the top 34 out of 7 million high school students around the globe.

Then he won a $50,000 grant from the Smart Tech Challenges Foundation to refine the technology.

He has since received additional grants, donations and private investment, and is currently raising a seed round for Biofire.

Read the media coverage about Kai’s invention.

“Kloepfer designed a smart handgun that fires only when a finger it recognizes is on the grip. More than 1,000 fingerprints can be authorized per gun, and Kloepfer says the sensor is 99.999 percent accurate.

A child can’t fire the gun. Neither can a thief — important here in a country in which more than 150,000 guns are stolen annually.

Kloepfer’s design won a grand prize in the Intel International Science and Engineering Fair. Then he won a $50,000 grant from the Smart Tech Challenges Foundation to refine the technology.”
