Hy-Conn was a quick-connect hose fitting that snapped onto hydrants in seconds. It worked perfectly. Firefighters loved it. And when the founder pitched it on Shark Tank, Mark Cuban offered $1.25 million for full ownership — plus a three-year job contract. But after the show… the deal fell apart. The founder didn’t like the fine print and backed out. Hy-Conn could’ve changed every fire department in the U.S. — but without funding, it stalled. A brilliant idea… just not the right partnership.
