Luck may have been what got Ring founder Jamie Siminoff cast for Shark Tank, but preparing for the pitch that supercharged his company required nothing short of Olympic-level preparation.

It had barely been a year since his company, DoorBot, had released its first iteration of a video-enabled doorbell, but that didn’t stop Siminoff from taking a leap of faith and applying to be featured on Shark Tank.

Out of the 30,000 or more people that applied to be on the popular business reality series that year, Siminoff said he was lucky enough to make the cut—and then also lucky to make it on air. Yet, making the most of his pitch was something else entirely, he told Fortune.

“We did get lucky, but lots of people get lucky and don’t take advantage of the luck,” Siminoff said.

For him, going on the show was just one of many pivotal moments in which he jumped in headfirst to take advantage of an opportunity that would later help make Ring the $1 billion success it is today.
