Looking for real AI case studies with practical business impact

[Ana]

Has anyone come across good AI case studies that go beyond theory and actually show how AI was applied in real business scenarios? I’m specifically looking for examples that explain the problem, approach, implementation, and measurable results.
Most content around AI is very conceptual, but I want to see how AI case studies look in practice across industries like healthcare, finance, retail, or manufacturing. If you’ve worked on or read any solid real-world examples, please share.
