I think this is a good initiative, so I share its link here:
Telesto just started now as a small startup, right after the alpha phase, but its platform is kind of competitive in design and functionality too + it wants to empower the ai developers with more frequent reward cycle than we usually saw on other competition platforms - rewards on every week, not after 1-2-3 months!
It also wants to empower the organizers with deployable, already working solutions weekly.
And last but not least, it doesn’t want to “steal” the organizers and competitors money - I just saying, because some other platforms organize for sooo much money and gives sooo little for the winners, it seems kind of stealing for me… and it’s very sad… 
So it’s not just for fun, and proof of concept, but fun and production at the same time 
This whole crowdsourcing iteration seems very attractive and interesting
Actually I helped to test its alpha phase with docker submissions, that’s why I know this platform doesn’t just exist, it also works properly.
But the platform needs competitions first - then it will have a lot of competitors I’m sure, so if anybody in this community wants to organize any ai competitions,
well, this is the place 
Here we could try out our best fastai codes and make real progress on the competitions in a fast & fun way ^^
