Tia Castle owes her business epiphany to Justine Musk.

In an online thread in 2015, the ex-wife of billionaire Elon Musk responded to the question: What does it take to become a billionaire? Justine Musk advised that one should become a master of two worlds that can be brought together to “make idea babies that no one has seen before.”

Castle had an idea for a TV show focused on luxury real estate, and Musk's words of wisdom helped her realize she could combine her expertise in television production and real estate to create a successful product.
