grammerly seems to be spending tens of millions in advertising with almost no apparent income being generated. they have market domination online and almost total saturation of the office desktop urban familiarity. this MASSIVE spend of many millions of dollars on advertising has come from what looks like absolutely no income stream. and then... Wikipedia has a dead end on who owns them there is no company web site thier official site is just a blank shop window for them to sell from. there should be numerous google results talking about the company and who owns them, who the directors are etc etc... but nothing this means they are spending large sums of money to keep their company hidden it seems all a bit cloak n dagger for something with such vast market saturation injecting code into almost every western world office computer and cell phone. if it were facebook the wall st wolfs would be trying to steal its family jewels.
