In this episode of Parenting Aces, host Lisa Stone welcomes Darren Hornig, founder and CEO of QuartzApp, a revolutionary new app designed to simplify the process of finding and booking tennis courts—along with pickleball, padel, squash, racquetball, and badminton facilities—anytime, anywhere. Hornig shares his personal tennis journey, rooted in a family legacy and inspired by legends like McEnroe and Borg, and explains how QuartzApp emerged from a deep frustration with the fragmented, inefficient system of court discovery and booking. The app acts as an 'Expedia of racket sports,' offering real-time availability, pricing, maps, and user reviews across 1,800 courts in the U.S. and Canada, with plans to scale to 10,000+ by 2026. It’s especially valuable for junior tennis families traveling to tournaments, offering instant access to courts for warm-ups, practice matches, and casual play—no more last-minute Google Maps hunts. Hornig emphasizes the app’s win-win model: clubs gain revenue from underutilized court time (up to 40% idle), while players enjoy convenience, flexibility, and dynamic pricing. The app also integrates future features like tournaments, lessons, clinics, and pro shop discounts, with a strong focus on inclusivity through partnerships with the Johnny Mac Project to support underprivileged youth. Lisa concludes by praising the app’s intuitive design and life-enhancing potential, calling it a game-changer for tennis families and coaches alike.

Introducing QuartzApp: The Future of Court Booking
“How has nobody thought of this and done this before now? But Darren to the rescue, he has created an all-in-one app where you can search available courts. You can book and pay for the courts. And then all you have to do is show up and play.”
Darren Hornig’s Tennis Journey and Vision
Hornig shares his lifelong connection to tennis, rooted in a family legacy and inspired by 70s legends, and explains how his personal experience led to creating QuartzApp to modernize the sport’s accessibility.
How QuartzApp Works: From Search to Booking
“It's a simple interface. You put in where you're located, what day and time you want to play, what sport you want to play... press search and it shows you all the courts very easily in a display but also in a map view with price and availability.”
Solving the Court Access Problem for Traveling Families
“When I was traveling with my son, we would open Google Maps and expand, expand, expand until we saw the tennis courts pop up on the map and drive there and hope that we were going to be able to get on a court right before a match.”
The Business Model: Win-Win for Clubs and Players
“The math is easy. The court's empty. What would you rather have? 75.80 cents on the dollar or zero cents on the dollar?”
“If there's a fountain of youth out there, it's racket sports. And if you play racket sports, you could do it on Quartz app.”
