Summary

In today’s episode, I sit down with Zack Fleishman, CEO and operator behind Shark Wheel and a former pro tennis player ranked No. 11 in the U.S. We talk about how two non engineers used biomimicry and a sine wave design to reinvent the wheel, then turned early chaos into real traction. Zack explains choosing focus over fads, why agriculture became the breakout market, and how Shark Wheel generated more than $15 million in revenue without a sales team. We also cover equity crowdfunding, moving from R & D to sales, and the athlete mindset that carries through long roadmaps, failures, and the push toward a massive 2026 inflection point.

Welcome to Entrepreneurs the Playbook. I'm David Meltzer here with Zach Fleischman and you've seen

them everywhere. CEO at Sharkwheel. Welcome to the playbook, Zach. Thank you for having me, David.

0:12.1

Very happy to be here. I'm super excited because I see so many deals in so many companies and a lot of

0:20.1

people tout innovation.

0:22.6

And there's very few that walk the walk or wheel the wheel, as I say, when it comes to

0:27.6

shark wheel.

0:28.6

You guys literally have reinvented the wheel.

0:31.6

And it doesn't get any bigger than that.

0:34.6

Yeah, it's actually true. We see that all the time, like, don't reinvent the wheel or it's impossible to square the

0:41.7

circle.

0:42.7

We've heard it a million times, but actually we have done that.

0:46.1

More specifically, David Patrick, who's the inventor and my co-founder, he's the one that

0:50.7

actually did it.

0:52.2

So he found that in nature, that's how nature moves.

0:55.7

Everything in nature moves in a sine wave. And when we started shark wheel, neither one of us knew

1:01.4

anything about wheels, to be perfectly honest, but, um, we knew about the science behind the wheel.

1:06.5

And so we knew that it was going to be successful because a sine wave shape just has inherent

1:12.6

advantages.

1:14.3

And when you look at other inventions that, you know, utilize biomimicry when they're

1:19.4

mimicking nature, you usually see those same advantages because nature certainly makes a lot of

1:26.4

good decisions and right choices. So sign wave movements

1:29.8

are seen, you know, it's why a sidewinder snake can stay on top of the sand. It's because it moves
