Tech. Sgt. Tom Burden, a weapons mechanic assigned to the Ohio Air National Guard’s 180th Fighter Wing, swapped his military uniform for a dark blue jumpsuit emblazoned with the Grypmat logo across the shoulders as he mingled with more than a hundred friends, relatives, entrepreneurs and investors at Rev1 Ventures in Columbus, Ohio. They stood together in small groups, discussing his invention while waiting for the newest episode of Shark Tank to air. Some speculated on the upcoming show. Would Burden get a deal? If he did get a deal, would it be what he wanted? Which shark would show an interest in his business? Would he even accept a deal if one was offered? Others speculated on the potential of his promising future; private jets, mansions, yachts and other various trappings of success. Some talked about their own inventions and Burden’s example of entrepreneurial spirit, dogged determination, and dauntless courage. Others spoke hopefully about investment opportunities with Burden’s self-built company.
