The number of employees doesn't really matter these days. Lots of the day-to-day boring stuff should be outsourced/contracted anyway, keeping the company lean and mean and focused on what makes it different from others. Helps when the bubble bursts too - you can scale down quickly without having to deal with thousands of layoffs.
Having said that, this one sounds particularly bubbly. I said the same about Amazon and Netflix years ago so you know I'm an expert.
It is the typical case in which even if the company follows perfectly their plans and realises all the gains that the investors are assuming, even in that case, the investors will not make a lot. I think that most people here have lived the dot com just like you, yet most of the lessons that should have been learned are not.
Now, for this case, even the most basic analysis disproves any possible real value for these companies. Cannabis is not an strategic product at all. It can be easily grown, it takes very little time to setup a facility and grow the product, the resources to produce it are abundant, the seed easy to get and the technology basically non-existant. No patents, no regional advantage...
This company does not have anything that can prevent another rival to do basically the same and possibly at a lower price. There is nothing justifying a premium price for it IMO.
