BrilliantPad

BrilliantPad is an automatic, self-cleaning indoor dog potty. The device sits like a tray on the floor, and after a dog uses it, the machine wraps up the soiled pad and rolls a fresh, clean surface into place, sealing away the waste so owners are not handling dirty pads by hand. It was created by Alan Cook, an inventor and entrepreneur who set out to solve the unpleasant, repetitive chore of changing puppy pads for small dogs and apartment-bound pets.

Cook entered Season 9 asking for 500,000 dollars for 5 percent. He showed how the automated roll-and-wrap mechanism worked, positioning it as a genuine convenience product for busy pet owners. Lori Greiner, a strong fit for clever consumer gadgets, made a deal. During the negotiation the structure shifted toward a per-unit royalty alongside equity rather than a straight cash-for-shares arrangement.

The product stood out because it automated one of the least pleasant parts of dog ownership, which is exactly the kind of practical problem Shark Tank viewers respond to. A working demonstration of the machine sealing away waste and laying a fresh pad made the value obvious on screen, and Greiner's interest signaled retail potential.

The handshake with Greiner did not finalize after the show, a common Shark Tank outcome, but Cook kept building the business independently. He refined the product over time with more absorbent pads, spill-resistant tray edges, and improved automatic advancement, and later added a smart, app-connected model so owners could trigger a fresh pad hands-free.

As of 2026 BrilliantPad is still operating and selling directly to customers. It has continued iterating on its lineup, including the app-enabled BrilliantPad Smart, and remains an active pet-product brand. That makes it one of the Season 9 deals that turned into a durable company even though the on-air investment did not close.
