## Summary

San Francisco AI company building persistent intelligent NPCs for gaming with 1M+ Roblox users in month one; $6.7M raised competing with Inworld AI for game character intelligence and social deduction AI.

## Company Overview

ego AI is a San Francisco-based AI company building persistent, intelligent AI characters for gaming environments — creating non-player characters (NPCs) that exhibit human-like reasoning, memory, and adaptive behavior in 3D gaming worlds and social deduction games. Founded in 2023 and backed with $6.7 million in early seed funding, ego AI achieved over 1 million users in its first month through a Roblox experience, partnered with MEE6 for Discord integration, and launched Accomplice (an AI-powered social deduction game), while collaborating with Singapore's government on AI infrastructure research.

ego AI's NPC intelligence technology goes beyond scripted dialogue trees: the AI characters maintain persistent memory of past interactions, build mental models of other characters in the game world, form goals and plans, and respond to novel situations with contextually appropriate behavior. In Accomplice (ego AI's social deduction game similar to Among Us), AI characters actively deceive, form alliances, and adapt strategies based on player behavior — demonstrating theory-of-mind capabilities that traditional game AI lacks. The persistence layer means characters remember players across sessions and develop evolving relationships.

In 2025, ego AI competes in the AI NPC and game intelligence market with Inworld AI (AI character platform, $50M+ raised), Convai Technologies (AI NPC dialogue and behavior), and the in-house AI character systems that major studios develop for AAA games. The market for believable game AI has grown as large language models provide the natural language understanding needed for open-ended NPC conversation. The Roblox integration is a significant distribution achievement — Roblox's 80+ million daily users provide a massive testing ground for AI character technologies. Singapore government collaboration provides academic credibility and potential Southeast Asian market development. The 2025 strategy focuses on game developer platform access (enabling third-party games to integrate ego AI characters), expanding the social AI game genre, and building the persistent world memory systems that enable compelling long-term character relationships.
