For those that are familiar with the service are they really mostly/only focused on companies that have outside investment?

From glancing at their literature it seemed like their gig was lending money to companies that actually already had the money in the bank, like providing company spending cards to a startup with a few million in VC money sitting somewhere.

Is that correct or do they lend to companies with more traditional economics, like a bootstrapped company with a million or two in annual revenue but without major cash reserves or investment?
