I may not be 100% correct, but...................
Some years ago, the Jacuzzi brothers, there were 3 or 5, I can't remember, had a falling out and each went into business for themselves. Funny thing, they each used their last name in the name of ther new company.
Jacuzzi Brands Inc's, Jacuzzi bath divisions, manufactures jetted bath tubs, NOT Jacuzzi portable spas.
