FYI: Last time I stopped at the bank where I opened business checking account 2+ years ago (Wells Fargo), they sat me down and offered a 100K line of credit (the interest rate was unknown unless I applied, but she said it would be around 7-8%). The service is poorly monetized ( disproportionately high hosting fees + new hardware expenses / revenue). Until recently I was putting all these hosting related expenses on a single US Bank credit card (and paying it off monthly). In response, they raised the credit line to 40k at 8% yearly interest. This is less however than the 300k, that I think is needed. Additionally, I would prefer to use this kind bank debt financing only in an emergency, because I suppose that unlike a savvy investor, Wells Fargo and US Bank would be absolutely inflexible if I say need slightly more time, and would drive the company into default by their blanket policy, regardless of the specific circumstances.
