I'm not really sure how I feel about this. It seems like they behaved pretty reasonably for a regular company, but as a fiduciary, they probably should have held off and not funded anyone without funds in the bank, vs. relying on a mid-term capital call. (I wonder who bailed on the capital call and why)
After this, I would probably be reluctant to move to Vancouver based on their line of credit promise unless I could see the funds in escrow; a LoC of $100k should mean $100k in an account I control, with equity going to them based on how much I withdraw. If they were Sequoia I'd be willing to accept a promise, but clearly how they have demonstrated they have pretty limited resources.
They at least seem fairly transparent about everything, so it's not dishonesty, merely bad judgment.
