I still don't get what they do, page-65

Depends how you value growing companies. I mention those companies based on whether or not their business model has a chance to succeed or not - and their demonstrated growth of market share.

I believe over the long term that is what will dictate success. UPD is the most speculative of the few I mentioned as it is earlier stage.

Not that I mentioned them but XRO is expensive right now for sure. However they scale incredibly well. If their market share in USA / UK grows in the same way as it did in Australia (and the early signs are pretty good) they will be successful. That is why they are nowhere near the most overrated stock on the bourse.
