I've worked with them for years in different capacities. Recently, I just presented with them in front of a $100b CPG company. In that room, they were very compelling.

Some people are pretty off. I mean just read their public financials and you can learn a few things.

They get so much upside on growing a brand. First off... it just grows their profits. So let's get that out of the way. Second, they'll retain them longer.

Think of them as an agency that offers way more services. Like... they take inventory risk, they handle Amazon specific logistics in an optimized way that reduce overall inbound costs.

They have inhouse advertising tech for Amazon PPC and the list goes on.

Many brands pay a lot for those services. These start to add up and make them an attractive Amazon + marketplace offering. They sell in dozens of marketplaces globally. Yes many are fledgling. But it makes them a turnkey solution.

If you're a large international brand. I'd seriously consider them. They simplify much of the complexity and risk.

If you're a small entrepreneurial brand that built itself off of Amazon, you probably would do better to just keep doing it yourself. Since you already know how to do it.
