You could call them haunted house specialists, but that wouldn’t do them justice. These guys at Ten Thirty One Productions take the idea of a haunted house and make it completely immersive. With their highly skilled special effects and make-up team, they make sure that the haunted events are something for their customers to remember. Ranging from the “Haunted Hayride” to their “Ghost Ship” attraction, it’s no wonder Ten Thirty One Productions is one of the most successful Shark Tank productions. They’ve made over $2 million with their idea and are expanding their team to bring the experience nationwide.
