At a point where I had something like eight years of operating history and showed a series of banks financial statements with mid six figures in revenue the overwhelming response was "Well we will
not automatically punt out of the conversation where we agree to loan you 10% of that topline number but underwriting is expensive and that is really small beer... have you considered just getting more credit cards? We can accommodate that."
Among other factors complicating the math: you know how easy it is to start a SaaS company? It is similarly easy to credibly claim you are starting a SaaS company. (It is rather harder to credibly claim you are opening a pizza parlor; you need to have e.g. a location under contract.)
If you offer $100k to anyone credibly claiming to open a SaaS company, and charge reasonable business loan rates... fraud is going to be pretty annoying.
Business failure is going to be pretty annoying, too! What happens when 6 months in the company is making nothing and Google offers the founder Google-appropriate amounts of money to get a real job? Answer: you lose all your money.
(VCs have a saying about this which is reasonably well calibrated: Don't take venture risk for debt returns. Bank of America is very much not in the business of taking venture risk in their SMB lending segment.)
