While poor credit may disqualify you from obtaining a bank loan, as a startup with no cash flow, you're unlikely to get bank financing anyway.
You'll probably have better luck with an investor who believes in you and your vision and is willing to contribute capital in return for a stake in your company.

Does having a poor credit rating mean I can never secure financing?
I have an idea for a business that I know will take off. However, my poor credit rating is being held against me. How do I win? I'm trying to be self-sufficient and not rely on welfare. All I need is a small loan. What are people in my position to do? Give up completely?
