Mirai Clinical Pitch
It is Koko Hayashi’s second time coming to the tank. Last time, she came to pitch a yoga company, but she didn’t have any luck securing an investment. However, the entrepreneur once again returned, this time with a new venture: Mirai Clinical. The entrepreneur gave an impressive pitch on Shark Tank season 16 episode 19.
She explained to the sharks that nonenal body odor is the reason behind that distinct “old person smell.” She revealed the secret that most Japanese people use to fight this odor: one of the tastiest fruits, persimmon. This fruit helps eliminate stubborn body odor.
She uses this natural ingredient to make body care products. Mirai Clinical offers Body Wash, Deodorizing Soap, Body Wipes, Natural Deodorant, and more.
Mirai Clinical reported lifetime sales of $8.7 million. Despite projecting $4 million in revenue for the current year, unforeseen circumstances, including a robbery, impacted their performance. However, they achieved $2.2 million in sales last year, yielding a net profit of $250,000.
The flagship Persimmon Soap Bar accounts for 53% of total sales. Its production cost is $1.85. While the retail price of $17.97. Mirai Clinical’s return on ad spend is currently 2.5%
