Sorted from oldest to newest. Anything missing?
Off the top of my head, I'd say Prokey and Klever but I'm pretty sure there's more...
I don't want to discourage you by any means, but it's worth noting that in the same sub-board, @maxirosson is already promoting an alternative website that lists almost everything in a very detailed manner, so there's a high chance you'd not be getting a lot of visitors
[unless you significantly improve your offerings].
BTW, I spotted multiple errors on the last two
[you might want to double-check other stuff as well]:
- BitKey in place of Block.
- Both of the years they've been founded are wrong.
