As your Amazon agency grows, one question becomes impossible to ignore:

Do you build your own analytics infrastructure—or buy a solution?

In this episode of Marketplace Masters, Paul Sonneveld sits down with John Aspinall (Velocity Sellers) to break down the real trade-offs behind this critical decision.

From messy reporting and scaling data pipelines to rising client expectations, they unpack what actually happens inside agencies as they grow—and why so many internal builds fail to scale.

You’ll learn:

•  The tipping point where manual systems stop working 
•  Why AI makes building easier—but not scalable 
•  The hidden complexity behind APIs, data pipelines, and reporting 
•  When building internally actually makes sense 
•  How enterprise clients change your infrastructure requirements 
•  And how to avoid costly “band-aid” solutions 

One key takeaway:
 Just because you can build it doesn’t mean you should.

If you're running or scaling an Amazon agency, this episode will help you make smarter, more strategic decisions about your tech stack.
