My suggestions are the following: (but you guys need to double check that for yourselves)
Experty - voice and video application, it is an international network for professionals i guess.
ArcBlock. ArcBlock https://www.arcblock.io/, it is one more platform for blockchain (there are so many of them and everyone claims to be the best.)
WePower - https://wepower.network/ Not sure yet. need some more time to get the idea but like it from the first glance.
