Krafton is coming off the best financial year in its history — and it’s now betting its future on the man who has quietly been rebuilding its AI engine from the inside out.
The South Korean gaming giant, best known as the publisher behind PUBG: Battlegrounds, has appointed Kangwook Lee as its first-ever Chief AI Officer (CAIO), a newly created executive role designed to anchor the company’s AI research and long-term innovation strategy.
For anyone tracking Krafton as an investment, this is not a routine C-suite shuffle. It is a deliberate structural signal.
Who Is Kangwook Lee — And Why Does His Background Matter?
Lee received his doctorate in electrical and computer engineering from the University of California, Berkeley in 2016 and served as a professor at the University of Wisconsin–Madison since 2019.
That combination of elite academic credentials and deep technical specialisation in machine learning, natural language processing, and reinforcement learning is precisely the profile you want leading an AI division that is expected to generate real commercial output — not just research papers.
Crucially, Lee recently resigned his tenured position at the University of Wisconsin-Madison to dedicate himself fully to Krafton’s AI R&D and mid-to-long-term innovation strategy. Walking away from tenure is not a decision academics take lightly.
It sends a clear message about where Lee believes the most meaningful and consequential AI work is happening right now — inside a gaming company with the data, infrastructure, and scale to actually deploy it.
Lee has earned recognition for his research with a total of 57 authored papers accepted at leading global AI conferences including NeurIPS, ICML, and ICLR.
In 2025, he led Krafton’s landmark collaboration with NVIDIA to introduce Co-Playable Characters (CPCs) — AI-driven companions capable of real-time interaction with players — one of the most tangible examples of generative AI being meaningfully integrated into live game environments.
What This Means for Krafton’s Business Strategy
Krafton’s AI strategy under Lee will operate across three pillars: elevating gameplay through features like CPCs, enhancing operational efficiency by reducing repetitive development tasks, and securing new growth drivers. That third pillar is perhaps the most intriguing from an investor standpoint. Krafton is establishing a separate entity — Ludo Robotics — with a parent company in the US and a Korean subsidiary that will be led by Lee himself, focusing on physical AI and robotics research.
For a gaming company to pivot into robotics software research using its simulation expertise is an ambitious long-term play — one that signals Krafton is thinking well beyond its current revenue base.
The Earnings Backdrop: Record Numbers, But Questions Remain
This appointment lands against a genuinely impressive set of financials. Krafton reported full-year revenue of 3.33 trillion won ($2.50 billion) and operating profit of 1.05 trillion won ($790 million), with revenue rising 22.8% from a year earlier — surpassing 3 trillion won for the first time in the company’s history. The PUBG franchise remains the undisputed engine, with PC revenues hitting an all-time high. New titles inZOI and MIMESIS each crossed one million units sold, providing meaningful proof that the pipeline beyond PUBG is beginning to mature.
However, the story isn’t entirely clean. Net profit declined sharply to approximately $503 million, down 43.7% year-over-year, with the fourth quarter posting a modest net loss as operating expenses peaked. Investors need to watch margin recovery closely as AI infrastructure spend scales up.
The appointment of a world-class AI researcher who has already delivered results is Krafton telling the market: the investment phase has purpose, and there is a credible person steering it. That, in the current gaming landscape, is a meaningful differentiator.
