Do I need a data analyst to use ecommerce analytics software?

No. You don't need a data analyst on staff to use ecommerce analytics software, and if that's the thing holding you back from adopting one, it's the wrong reason.

Here's where the confusion comes from. Raw data warehouses and general-purpose BI tools (think a bare Redshift instance, or Looker configured from scratch) genuinely do need someone who can write SQL and build data models. That's not a myth. But purpose-built ecommerce analytics platforms are a different category entirely. They're built so a founder or marketer can open a dashboard and get an answer, not a blank query editor.
