I once worked as a software engineer at a YC startup which claimed to provide some kind of an “enhanced credit report” for landlords to check their prospective tenants. Millions of people had used their software. When I checked their codebase I found out that they literally just pulled an existing Equifax report, repackaged it in a slightly different format, and made up some completely bullshit numbers out of thin air (some were literally random numbers that could not be reproduced even with the same inputs). This startup received several rounds of funding in the millions of $ and had over a dozen software engineers.
