Well, if you survey the space we are looking at you will find good commercial reasons for that form factor. Such as: size of available spaces under typical vending leases, fits through door, fits in lift, fits in corridor, fits in truck, etc.

I don't think anyone will ever argue that you know your market well!

I think what people are trying to say is that there maybe ways to get a partial solution to a smaller part of your customer base much quicker and for less money.

Yes. There may be. But there's no solution cheaper or faster than letting someone else prove the market on your behalf. In our case, we have seen enough proof in the last few years: last mile delivery commodification, 50% of every $1 spent in food retail is convenience-driven, etc. We do not need to prove humans want food or that frustrated demand exists. What we need to prove is that we can supply it, cost effectively, profitably, at scale, with technology we uniquely design, manufacture and operate with a defensible lead.
