The US owns the money printer to the world trade currency (USD), and has the military force to defend this unique position, so of course it can afford to outspend everyone else.
No, kids, if Saudi Arabia suddenly started selling all its oil in Euros or Yen on renminbi, the US would not send the Sixth Fleet off its shore, any more than it did so to force KSA to use the US dollar to price its wares in the first place. Saudis (and Russians, and Chinese, and everyone else) use the US dollar because they find that a) using it is more convenient than another hard currency like the Swiss franc or British pound, and b) no one else wants riyals, rubles, or renminbi.
I can make the same argument without mentioning the military - we benefit from a virtuous cycle of having the most dynamic economy which allows us access to credit to improve it, making it even more dynamic, and we simply pay it back as a lesser share of % GDP later.
It has nothing to do with the federal reserve and everything to do with risk tolerence.
The Canadian risk/reward curve is weird. They won't look at anything barely promising but will go "all in" once it hits a bit of traction (even if the business model is wonky)
Also, we were near completing a $10k/month enterprise deal but didn't have the runway to finish those sales in time. Additionally, we had Government of Canada contracts at $3k/month in the pipeline, which we did eventually complete. Our software was running on millions of phones, we had enterprise pipeline deals, signed government contracts (hard to come by I hear!) and a darn good team.
Hard to say how it would have played out, but, what's clear to me is that it wasn't clear that the $300k would have been lost.
I tried to raise a ~$300k seed round in Toronto in 2014. Most Canadian investors we met with wanted to see us have something like $10k/month in recurring revenue before considering an investment. We spent a week in SF and left with a $250k offer at a $4M valuation, when we were pre-revenue!
(We declined, and eventually our business failed (acquhired by a team in SF, though....). But still. Wow! What a difference!)
