David Money is a construction worker who first competed in American Ninja Warrior 2 and he beat the qualifier in 40.52 seconds, which was good enough to earn 2nd place. In the Semi-Finals however he failed on the Salmon Ladder like many that day and did not advance to boot camp.
In American Ninja Warrior 3 David returned and easily progressed through the first four obstacles, but he missed the second bar modified Jumping Bars and failed.
In American Ninja Warrior 4 David started strong, but started to lose stamina on the Devil Steps and he didn't have enough energy to scale the Soritatsu Kabe. Despite this, his time past the Devil Steps was good enough for 30th place. In the Semi-Finals, David cleared the Devil Steps at a more steadier pace and because of this he managed to get up the Soritatsu Kabe that beat him in the qualifier and he even beat the Salmon Ladder that took him out in American Ninja Warrior 2, but he didn't have enough strength to get past the Arm Rings and he placed 17th overall. David was however, selected as one of the ten wildcards to compete in Las Vegas. During his run he started strong, but struggled on the Soritatsu Kabe and he took long pauses before the Half-Pipe Attack and the Spin Bridge, causing him to time out on the Rope Ladder about halfway up. Nevertheless, he was satisfied with his performance.
