As a first approximation, running from any startup that is backed by the Saudi sovereign-wealth fund (and Softbank Vision fund which is mostly just another name for the Saudi money) is likely a good investment strategy. Basically, any company that has great prospects is going to be able to get money from other funds with a lot less baggage. In addition, founders who take that money likely have ethical issues and will happily screw the investors (see WeWork CEO).
