About Soulthread — Memory-Driven AI Agents
Soulthread is building the next category of AI entertainment: memory-driven interactive narrative.
We believe characters should remember—not as chat logs, but as lived experience. We believe stories should respond—not as pre-written branches alone, but as worlds shaped by what you say and do.
Our team brings together narrative design, AI systems, and global product experience.
We're launching first in North America and Western Europe, with expansion to Japan, Korea, the Middle East, and Southeast Asia.
Headquarters: Sheridan, WY · United States
Narrative
Crafting living worlds and unforgettable characters where memory creates meaning and depth.
AI Systems
Building memory-first infrastructure and models that understand context, intent, and consequence.
