Oswarld (Kwangseob Ahn)

LinkedIn

GTM Consultant · Founder of INLEVEL9 / Adjunct Professor at Sejong University

Drawing on his GTM strategy work at Gamma, Oswarld helps decide who to serve, what value to offer, how to price it, and how to sell. INLEVEL9 is a solo consulting firm where he delivers consulting and coaching directly.

The consulting practice began as OBF and continues as INLEVEL9. Kwangseob Ahn (안광섭) also works under the name Oswarld (오스왈드).

At INLEVEL9, he helps companies adopt AI, transition to it, and prepare for it while shaping market-entry, product, and GTM strategy. His path spans game projects at Nexon, finance at Hanwha Life, Notion’s Korean launch and community, AI products at Kakao Brain, and GTM strategy at Gamma. Across industries, the work has remained consistent: connecting products with markets and technology with people. His current research asks what conversational AI should remember, forget, and verify over long-running human relationships. He holds a master’s degree in Management of Technology and an MBA from Korea University and wrote Homo Brainless: The People Who Outsource Their Thinking.
