Ask HN: Unknown side effects of starting a new company?

I am currently thinking about starting a start up, and to fund it getting a "company" credit card. However, I don't know how that would affect my credit score.

Due to that side effect, I started thinking about other potential unknown "costs" I haven't thought about. What are some you have ran into?

  • The biggest cost for a startup is to try to act like a company to look good in front of others.
