Where Do You Find Real-world Datasets With Actual Business Problems To Solve?

I’ve worked with common datasets from Kaggle and UCI, but I’m looking for more realistic data sources tied to actual business or operational problems.

I’m especially interested in datasets where analysis could answer questions like:

• Why sales dropped in a region
• Customer churn patterns
• Inventory or supply chain inefficiencies
• Pricing opportunities
• Marketing campaign performance

I’ve already explored Kaggle, UCI, and some open government portals.

For those who build portfolio projects or practice real analytics work:

1. Where do you usually find more realistic datasets?
2. How do you turn raw public data into a meaningful business problem statement?
3. Any underrated sources (APIs, city data, company reports, scraped public data, etc.)?

Would appreciate hearing your process.
