Growth Mavericks

🐒 The Joe Rogan Effect, Monkey Feet, and the Reality of Explosive Growth

What happens when Joe Rogan talks about your product on his podcast?
For Paul Jackson, co-founder of Animal House Fitness and creator of Monkey Feet, it meant $15 million in revenue in the first 18 months. 

The product itself is deceptively simple: a device that straps to your foot and allows you to attach dumbbells so you can train your legs the same way you train your arms.
One product.
 One SKU.
 Built out of a travel trailer during COVID.
Then the internet found it.
But what makes this episode powerful isn’t just the rocket-ship growth — it’s what happened after.
Paul gets brutally honest about the realities founders rarely talk about: inventory mistakes, cash crunches, over-reliance on paid ads, and the challenge of building a durable business after viral success.
