This looks like a slightly inferior version of https://streamyard.com/ (in particular, fewer participants at each price level) - do you have any value propositions above what they offer?
We're actually have all the features of their Professional plan ($50/month) at half the cost.
The on-screen participants per live stream is something we've capped at six for usability reasons (livestreams just don't look good with 10 faces on a stream).
Thanks for explaining! Hope you're able to get it into public beta soon.
edit: I also realized that "slightly inferior" was denigrating, which wasn't really how I intended it, even if you took it as a compliment. Sorry about that.
