Consider the issue of "rapid growth" vs. healthy growth.
If growth is too rapid, resources get stretched and the beast is weakened. A good product quickly faces poor support and gets publicly panned. Vultures flock in.
Wave has managed to stay debt free and grow at a sustainable rate while keeping a good face on customer support. This may be a bit too slow for "make me rich now" shareholders, but the process has proven just about right for internal structural strength. Q1 results will validate this and we should see SP respond. The short vultures will fight hard, but their days are numbered now by months rather than years.
