Season 4
Season 4 was when the classic shark lineup locked in. Kevin O’Leary, Daymond John, Mark Cuban, Barbara Corcoran, Lori Greiner, and Robert Herjavec were all regulars now, and there were no guest sharks this season. Just the main six going at it for 26 episodes.
This is the season that gave us Scrub Daddy, which went on to become the single most successful product in Shark Tank history. Lori invested and the rest is cleaning sponge history. Drop Stop was another big one, that thing that fills the gap between your car seat and the center console.
Other notable products include Freaker USA Koozies which were these one-size-fits-all drink insulators, the HoodiePillow which was exactly what it sounds like, and Nuts 'N More doing protein-packed peanut butter. The show was pulling in around 6-7 million viewers an episode at this point and clearly hitting its stride.
