At a smart business, you work for your customers. If you're at a company that works for your investors, you're going to have this problem over and over again. In fact, you might as well give up on the idea of planning and decision making based on what would be best for the product and your customers.
> Well, then you're bound to the amount of money customers can give you.
You’re _always_ bound by what the customer is willing to pay.
Speaking more expansively, it’s just a proxy for whether the market will bear your prices/wants your product, and whether you are in the right place and/or positioning your product correctly.
VCs just add a temporary runway so you don’t have to be as concerned about that.
