I am not familiar with EVEDO but I am familiar with COTI and NOIA, Those two are real gem indeed, ive seen them getting good investments and comments which makes it a more reliable investment for me
Referring back to what I said above, you don't just make a real gem just from getting good B2B partnerships and investments and "comments" as you put it!
B2B looks great for PR and marketing but at the end of the day if the actual users aren't talking or using the network, it's truly pointless and doomed to fail.
