Peer-to-peer loans. The Lending Club, which matches borrowers with investors, publishes a dataset of all loans issued through its platform since 2007. The dataset’s many fields include each loan’s amount, term, interest rate, grade, status, and purpose (as a category, and often also a fuller description), as well as the borrower’s employer, home ownership status, and annual income. You can also download all declined loans, i.e., those “that did not meet Lending Club’s credit underwriting policy.” [h/t Charlie Stanton]

Sneaker factories. Nike, Inc.’s manufacturing map displays 618 factories and material suppliers that the company uses to manufacture its products (as of May 2018).

Retail stores and products. Best Buy’s API and Walmart’s API both let you search their products and stores. Both also require (free) registration to obtain an API key. In 2016, Best Buy also published bulk data describing its products and stores. [h/t Dan Nguyen + Dave Machado]
Financial statements. The SEC’s Office of Structured Disclosure publishes data extracted from corporations’ public financial statements. That dataset contains the numbers listed in each company’s primary financial statements — balance sheets, cash flows, et cetera. An even more detailed version of the dataset includes plain-text notes from the filings, plus numbers from a broader array of forms. Both datasets are updated quarterly and go back to 2009.
