The Sharks Don't Buy the MinusCal Claims
Mark Cuban takes issue with the claims of the MinusCal entrepreneurs, Barrett Jacques and Crom Carmichael, and they all get into a heated argument over the product's capabilities. Robert Herjavec says Mark's 'level of arrogance really pisses [him] off,' and wishes that Mark would let people talk. But as Barrett and Jacque continue, they chase everyone away. From 'Episode 1,' the season 11 premiere of Shark Tank. Watch Shark Tank SUNDAY 9|8c on ABC, streaming, on demand, and Hulu.
