Investor $1M Isaac Choi

Where's the 4M here that the OP was writing about? She could have checked crunchbase to see that the startup doesn't have money.

Anyone with an account on crunchbase can contribute any information about a company. The information is not official. It is crowd-sourced. Which means the info can be fake.

Is Crunchbase a 100% reliable source? How do they do their due diligence?

They don't at all. I've seen significant errors before. It's usually vaguely correct, but when you've got a manipulative liar running your company, Crunchbase isn't going to help.
