The problems is I have no contacts in the business so I have no way of knowing what users actually need, and whether they would even be open to using insights from an app. Normally that would be the end of it, because I have zero experience in marketing to that sector. But I'm wondering if there's a way for me to get in contact with people in the restaurant industry and see if they'd be interested.
Are there any strategies for making contacts in domains outside of your own? How can you find people to work with you who aren't in tech?
In times of COVID-19 this does not apply, but if you go to a Subway franchise, a cafe or any kind of restaurant during off hours you might meet the owner or a manager. For years I've gone to the food court at the Subway at the mall and talked with the owner about business and life.
