There hasn't been visibility about this point. I also pointed this out to Helix. It is a dead certainty that if money does not start coming in at some point, then they can't survive. But that doesn't mean that Helix just bought all the machinery up front. There are much smarter ways of doing it, such as leasing. Also there are government incentives that a startup can capitalise on. These measures alone would stretch the Kickstarter dollar quite a bit, enough to last until now at least. The operating cost probably has been quite modest up to recently at least - a one man show, no orders placed until design was final, paying things off, leasing machinery and so on.
