Screenhero co-founder/CEO here — this is really great! It looks like we had similar feelings after leaving our acquiring companies with our products being sunset.

Since leaving Slack, I've been building Pop with a new team. The first product we launched in 2020 is essentially Screenhero 2.0 (pop.com). Since then, we've been building an expanded product: a virtual office for remote teams, which is now almost ready for launch (there's a waitlist at https://new.pop.com). We've even got Wayland support in! We have plans to open source a part of the Wayland piece, which Petal could potentially use too.

I do love this space, and wish more tools were about live collaboration — it feels so much more human and fun than single-player mode. I hope Petal becomes a growing community that thrives for the long haul!
