Were I a large investor buying something I would: 1. Ask them to let a few of my men to dig into the source code and database in their presence. 2. Hire a company to do investigations, speak with their employees, former employees, customers, investors and businesses partners 3. Use an escrow service, a trusted third party which will verify their claims 4. State in the contract that if the deal goes through and if I discover more than 1% of their claims is fake, they own me double the money But in this case, the article states JP Morgan was sent all the fake data. They just didn't care to verify it. That is either stupidity or JP Morgan have some careless employees which don't risk anything if their employer loses lots of money because they don't do their jobs, so it might be nepotism.
