If anybody noticed, in that Jan 2018 letter, it states "...the costs, speed and material impact for ANY organization has accelerated to the point where we work with clients of all sizes – from 5 employees to over 200,000 employees."
For any doubters of this company, businesses that employ over 200,000 people don't just pick some shady OTC listed pump and dump to do business with, they do their DD.
The chart is going through a completely normal pattern for something that broke out like this, and it's still way up from 1 month ago. I could show dozens of charts from other stocks that break out like this, retreat back down sharply, then continue on upwards to new highs.
