• Quant employment verification: CONFIRMED. The indexed LinkedIn record (enrichment source 07abf) lists two actual employment roles at Piematics - Quantitative Trader (2020-2021) and Quantitative Researcher (2017-2019) - both paid work roles, not student programs, competitions or insight days. Piematics is an investment firm: its own site (piematics.com) self-describes as 'PIEMATICS Scientific Investment'. Identity is supported by the same indexed profile carrying a coherent career chain (Piematics -> AIRS Medical -> Levit -> Unstop -> Klim Ventures) plus SNU medicine and Seoul Science High School education. Caveat: the Piematics roles rest on a single indexed/aggregator profile, which is NOT an independent primary-source confirmation, and no separate contemporaneous public record of the Piematics employment was found.
• Won a gold medal at the International Mathematical Olympiad 2010 representing the Republic of Korea (contestant id 19697; scores 7,7,7,7,0,0; total 28; rank 27; award 'gold'), per the official IMO results page.Jul 1, 2010
• Career timeline from the indexed LinkedIn profile: Quantitative Researcher at Piematics 2017-2019 (2 yrs), AI Researcher at AIRS Medical 2019-2020 (1 yr), Quantitative Trader at Piematics 2020-2021 (1 yr), Problem Solver at Levit (Alwayz) 2022, Founder & CEO of Unstop from 2022, Product Owner at Klim Ventures from 2023 - a return to Piematics in a trading role after the researcher stint.
• Identity caveat: the person carrying the Olympiad identity (Sanghun Song, IMO 2010 Korea gold) and the Seoul-based operator on LinkedIn share the name and a science-high-school/SNU profile, but NO source was found that explicitly links the two, so they are treated as probably the same only tentatively.
• Joined Klim Ventures in January 2023 as its newest member (Product Owner); the firm states he 'had been a close friend of Klim ventures for years', i.e. the hire followed a pre-existing relationship rather than an open application.Jan 1, 2023
• Founder & CEO of Unstop (언스탑), Seoul, since 2022, listed as a concurrent current role alongside his Klim Ventures product role.
• Worked as an AI Researcher at AIRS Medical (airsmed.com), Seoul, 2019-2020 - clinical AI/medtech, before returning to Piematics as a trader.
• Piematics classification: a Seoul-based investment firm self-described as 'Scientific Investment'; indexed as 'Piematics' (piematics.com), Seoul, 2 employees category / IT Services and IT Consulting - a small boutique, so his two stints there are a substantial part of his early career, not a large-firm credential. Not a bank or a large fund.
• Career-shape read: the sequence research -> AI/medtech -> trading -> early-stage consumer -> venture operator -> founder shows breadth rather than a deepening quant track; his quantitative-finance exposure is concentrated in the 2017-2021 Piematics years, and no role at a bank, asset manager, hedge fund or crypto/energy trading firm was found.
• Held a 'Problem Solver' role at Levit / Alwayz (레브잇, alwayz.co), Seoul, in 2022.
• Education: Seoul National University (field: medicine, 서울대학교 의학) and Seoul Science High School (서울과학고) - a science-gifted high school consistent with an early Olympiad trajectory; this is index-only data.
