Tattoo care brand Mad Rabbit has a mission to make a growing niche of body care mainstream.

The company, which first launched in 2019, makes products for people with tattoos. That includes body washes, balms and other aftercare needed to make sure the ink doesn't fade. And while it's recorded large sales growth year-over-year, seeing over 100% sales growth over the last two years (with the help of an appearance and subsequent deal on the show "Shark Tank"), it believes mass retail is the next arena in which to prove itself.

"Where do you go [from where we are now]," said co-founder and CEO Oliver Zak, "it's beauty and mass." Zak joined the Modern Retail Podcast this week and spoke about his ambitions for the brand.

The mass part of the retail expansion equation is already in the works. Just this week, Mad Rabbit unveiled plans to expand to over 1,800 Walmart locations. But the question is: how do you ensure that people will buy the products on the shelf?

According to Zak, it's a question of messaging. "I think a big key is screaming tattoo on the signage opportunity that you do have," he said. "I've never walked down a Walmart and seen anything related to a tattoo before."

Another big part of his strategy is gaining acceptance from the tattoo community. "When we first entered the industry, the biggest barrier we had was that we weren't tattoo artists," Zak said. "Many of them have a problem with 'outsiders' coming in and making money off the backs of tattoo artists. And to a certain extent, that is what we're doing."

But over the years, Mad Rabbit has tried to partner with all types of tattoo artists and make them know that they aren't mere suit-and-tie interlopers. That has begun paying dividends now, Zak said.

"This past year at conventions," said Zak, "it's been nothing but love."
