Variety of datasets for 30 use cases

I'm looking to build out 30 different use cases for 30 days where I pick up real data from multiple domains for eg - finance, technology, gaming etc. I want to run the data through a business reporting tool I came across and want to convince my peers/seniors in my firm that it's a great product. My real question - which all domains should I focus on and where can I real messy data for each of those domains. Any help is appreciated. Thanks. submitted by /u/superProgramManager [link] [comments]
