Who We Are
The Story Behind the Strategy
We didn’t start Rainmkr to play it safe—we started it to raise the bar. Our founders come from the trenches of Amazon growth, CPG, and digital marketing, with deep experience in brand aggregation, acquisitions, and high-performance ecommerce.
After building and scaling health & wellness brands through acquisition and growth, we saw the same problem everywhere: bloated agencies cutting corners, offering low-cost labor over real expertise.
So, we built the agency we wish existed. A powerhouse of elite operators, strategists, and brand thinkers who know Amazon inside and out.
No fluff. No gimmicks. Just real strategy and revenue results.
We believe better isn’t bigger—better is better.

Built for brands that demand more.
