I work in the "realtime" space too (founder of Fanout, low level push infra).
Liveblocks looks like it's somewhere between Firebase and Sendbird, providing live updates and state management, but for specific use-cases and stopping short of the UI. I haven't seen too many products operating at that level of abstraction, so maybe you're on to something. I also like how you solve for more use-cases than chat, the dominant "block" in the market.
