The backstory
Inworld builds conversational, memory-holding NPCs for games. The character framework, safety rails and runtime integration are real engineering. The pressure is that realtime voice and cheap reasoning APIs let a studio build its own version, and studios prefer to own the character layer. Wounded, pivoting toward runtime infrastructure.
