Hey, I'm Sam πŸ‘‹

You know how everyone talks about "data-driven decisions" but nobody actually knows where to start? So what I do is build tools that bridge that gap β€” from customer churn prediction models to AI-powered analytics. In fact, I've spent 10+ years in customer analytics and now build the AI tools I wish I had back then.
