CROSSNET is a backyard/beach game that combines four square and volleyball .  It was founded by Greg Meade , Chris Meade, and Michael Delpapa.  CROSSNET has been featured in Future Sharks . 
Beginnings and Development
After Michael came home for the summer from graduating college, he met up with Greg and Chris to brainstorm business ideas.  Greg suggested that there was a need for higher quality beach and backyard games.  Growing up, they all enjoyed playing four square together, and Michael inquired Greg of what he thought about four square volleyball.  From that idea, CROSSNET was born. 
Upon meeting with a patent attorney, they were informed that there was already a patent on the product idea.  They cold-called the patent holding and made a deal to obtain the rights to it.  After taking over a year to obtain a patent, they began the process of creating rules, designing and manufacturing the game, and make adjustments from feedback.  Their efforts took well over a year. 
The playing field is set up into four squares.  The player in square 4 serves from out of bounds to the player in square 2 who then can return it to any player.  Whoever is eliminated must return to square 1 and everyone rotates clockwise.  You can only earn a point if you are in square 4 and whoever gets to 11 first (or wins by 2) wins the game. 
Growth and Success
CROSSNET grew by establishing a physical presence on the beaches of Florida as well as having active Facebook and Instagram accounts.    In order to successful promote itself, CROSSNET attempted to create engaging ads on those platforms as well.  As of April 2018, CROSSNET had over 10.7k followers on Instagram .  The game is currently popular on the beaches of Florida and San Diego . 
In the future, CROSSNET plans to expand to a global scale.  Later in 2018, an indoor model for CROSSNET is set to be released that is targeted towards black tops, gyms and schools to use.  The founders envision CROSSNET to become commonplace on every major beach, have tournaments hosted across the world, be sold in retail stores, and become incorporated in physical education curriculums.
