Amazon Zoox self-driving vehicle

One pattern I've noticed with e-commerce tool stacks: sellers tend to over-invest in the Amazon-side tooling (repricing, PPC optimization, listing tools) and under-invest in the sourcing and cost side. The sourcing side is where most of the actual margin is made or lost, but because it's less quantified and more relational, it gets managed informally. That asymmetry creates real leverage for anyone building structured tooling for that side of the workflow.
