Write a customer case study

Write a customer case study from this material [interview notes, transcript, or call recording link]. Structure it as: customer background, the challenge they faced, why they chose us, how they rolled it out, and the results with specific numbers and a pull-quote. Keep the customer as the hero and our product as the enabler, match a confident marketing tone, and flag any claim or metric I need to confirm with the customer before publishing. Write it into a Google Doc.
