No that's why asking you sir , can you explain please 

Sorry I thought I answered the question.  They're a start up developing a ground breaking tech, that requires time and money.  Practically all tech starts up have to go through this and most will fail.  Some, will make it and thrive and my bet is on the latter.  The fact they're achieving this on a shoestring is to be admired.  The industry has spent billions without great success.

Whilst they haven't sold any end products, they have sold, successfully, to the likes of Celestial Ai, Sanan, Fibretop etc.  All of whom appear to be bought into what poet offers.  Sure, it hasn't yielded much revenue to date, but that's about to change.  Question is, do you believe they will and in large quantities. If not, then it's time to cut your losses (if they exist). 

Good luck to you
