Oswarld (Kwangseob Ahn)

Kwangseob Ahn, also known as Oswarld, teaches business analytics and data management at Sejong University and leads strategy consulting at OBF. His work covers market entry, product strategy, GTM, and AI adoption. He is most interested in what happens after a strategy deck: whether the idea becomes a product, a workflow, or a result in the real market.

He began his career managing game projects at Nexon. He later worked across finance at Hanwha Life, Notion’s Korean launch and community, AI products at Kakao Brain, and GTM strategy at Gamma. The industries changed, but the job was often the same: connecting products with markets and technology with people.

His recent research asks what conversational AI should remember, forget, and verify when it works with people over time. He also runs Daily Arxiv, a daily curation of AI research.

He holds a master’s degree in Management of Technology and an MBA from Korea University and is the author of Homo Brainless: The People Who Outsource Their Thinking. In OZ Talking, he writes every other day about how shifts in AI, business, and society connect. The aim is not to add more information, but to leave readers with a signal they can use.
