First into the tank are Ben and Ariel Zvaifler of PupBox, seeking $250,000 for 10 percent equity.

PupBox makes raising your furry friend much easier with their monthly subscription box. The boxes include training tips, meaty treats, toys, essential accessories and chews. Based on your puppy’s profile, customized items are selected for each box. The inspiration for the box came from wanting a better way to train puppies and help them better learn the essentials of puppyhood. Their most popular subscription box, for three months, costs $102 total.

After delivering a puppy to each shark, Lori Greiner questions how long the puppies really need the products included in the box, however, they also have adult dog boxes. They have done $580,000 in sales based mostly through social media and are expected to do more than $2 million next year.

Kevin O’Leary thinks their valuation is too aggressive, but they believe their predictions are attainable. Mark Cuban goes out since he’s not a fan of subscription businesses. O’Leary offers $250,000 for 20 percent, while Daymond John offers $250,000 for 25 percent, citing his doggy connections.

Robert Herjavec likes the idea and offers $250,000 for 15 percent, but he wants an immediate answer. They question whether any sharks would partner up, which John quickly declines given the amount of value he could bring to the business. Ultimately, they accept Herjavec’s offer because the don’t want to give up that much equity.

Each week on “Shark Tank,” budding entrepreneurs have the opportunity to pitch their emerging business to six multi-millionaire and billionaire investors, known as sharks: Mark Cuban, owner of the Dallas Mavericks; Daymond John, fashion mogul and founder of FUBU; Kevin O’Leary, self-proclaimed Mr. Wonderful and founder of O’Leary Financial Group; Barbara Corcoran, real estate maven; Lori Greiner, queen of QVC; and Robert Herjavec, technology guru and founder/CEO of the Herjavec Group. Venture capitalist Chris Sacca is also slated to appear as a guest shark this season.

“Shark Tank,” which is based on “Dragons’ Den,” is produced by Mark Burnett and first debuted in 2009. To date, the sharks have invested more than $87 million in various companies after engaging in numerous bidding wars and shark fights. A new episode airs each Friday at 9 p.m. on ABC.
