One man’s marine navigation app is riding a new wave of success. This all comes after his daughter posted a 12-second TikTok video of her father Jeff Foulk at a boat show in Chicago. No one was taking the time to look at his flyer in person, but online, those 12 seconds have been seen by almost 23 million people. A sad dad is no fun. But to Megan Foulk, 20, her dad’s sadness proved to be a business opportunity.
