@just-at-uber We should add Coinbase and HashiCorp, too. I'm also working on publishing the talks they gave in our recent meetup. I don't know if we have received permission to use their logos, yet, though.

Also, there are a few companies on that list that I'd like to double-check before publishing the list. Let's sync up offline before merging this PR.

And we should add Uber logo as well :)

Is there still more work to be done on this PR or can it be merged as is? Just thinking that having some real Cadence user logos on the main page will help show how our usage is growing.

So, I followed up on this issue and seems that Cadence Workflows would need permission from these companies in order for their logo / name to be featured.

I'm following this up with legal review from Uber in order to gather requirements of what's needed. A possible solution would be to create a google forms for companies to be featured.
