TLDR: William Santo, CTO of Kaiko Studios, is spearheading the integration of emotionally intelligent AI into gaming. This initiative aims to transform non-player characters (NPCs) from static entities into dynamic, emotionally responsive agents, fostering deeper player immersion and more personalized gaming experiences. Kaiko HQ is developing the foundational ‘EQ Layer’ for AI, enabling real-time emotional perception and response, while Kaiko Studios focuses on creating intellectual properties that leverage this emotional AI infrastructure.
William Santo, the Chief Technology Officer at Kaiko Studios, is at the forefront of a significant shift in the gaming industry, advocating for the profound integration of emotionally intelligent Artificial Intelligence (AI) into gameplay. Santo posits that the next major frontier in gaming lies not merely in smarter AI, but in AI that is deeply emotionally attuned, capable of transforming non-player characters (NPCs) from what he describes as ‘hollow shells’ into dynamic, emotionally resonant entities.
According to Santo, the core engineering mission across the industry is now prioritizing the development of foundational systems that merge emotional intelligence (EQ) with AI, aiming to create interfaces that ‘feel genuinely human.’ This breakthrough, he explains, involves developing powerful EQ abstractions that grant AI agents an intuitive grasp of human emotion. When combined with fluid internal-state systems, this architecture allows characters to evolve persistent personalities and draw from emotional memory, moving beyond scripted reactions to deliver contextually aware, continuity-driven responses.
Kaiko HQ, the parent company, is dedicated to building this ’emotional infrastructure for AI,’ founded in 2025 with a mission to make AI emotionally aware, ethically responsible, and deeply human. Their proprietary EQ Layer helps developers build AI systems that understand not just words, but feelings. Kaiko Studios, built on this foundational work, then translates this EQ infrastructure into living, playable experiences.

Santo emphasizes the transformative impact on gameplay, stating, ‘Instead of reacting following a script, these characters ensure their responses feel alive.’ This technology is poised to revolutionize narratives by embedding emotional context directly into AI, empowering designers to craft deeply immersive stories. Player-NPC relationships are expected to evolve organically, with characters’ emotions and behaviors reflecting player actions. The anticipated results include heightened player investment, personalized experiences adaptable to diverse preferences, and improved retention through emotionally attuned virtual worlds. Santo further notes, ‘We believe AI shouldn’t just be smart, it should be emotionally attuned,’ and likens Kaiko’s role to that of an operating system, making it possible to ‘build emotionally intelligent AI by default.’
