What Makes Ethan Different
Backed Unicorns Early
Made early-stage investments in Toss and Dunamu. Combined value: $18B+.
vs Industry: Most VCs have 0-1 unicorns and invest at later, safer stages.
Created 4+ Original Frameworks
Four Lenses, Optimism Tax (72M trades analyzed), MAU Trap, AI Native VC. Data-driven, reproducible, actionable.
vs Industry: Most VCs use inherited or generic frameworks.
20 Years Bridging Global & Korea Markets
Qualcomm Ventures (global) → Google (tech) → Samsung (Korea) → KB Investment (finance) → TheVentures. Sees patterns others miss.
vs Industry: Korea VCs only know Korea; US VCs only know US.
Operator-Investor Model (Building 15 Ventures)
Not just capital allocator. Actively building companies. Real skin in game. Knows what founders face.
vs Industry: Most VCs are pure financiers, not operators.
AI Native VC Pioneer (Vicky System)
Built end-to-end AI system for deal flow, diligence, portfolio monitoring. Learns from actual outcomes ($18B+ portfolio data).
vs Industry: Most VCs still use spreadsheets and gut instinct.
Publicly Accountable (Tracked Predictions)
All predictions published and tracked (/predictions). 2019 predictions came true. 2026 predictions in progress.
vs Industry: Most VCs avoid accountability, cherry-pick wins.
Frameworks Created by Ethan
Four Lenses Framework
Every investment decision analyzed through Finance, Global, Big Tech, and VC perspectives. Best opportunities light up all four lenses. Used to identify Toss and Dunamu.
The Optimism Tax
Analysis of 72 million prediction market trades ($18.26B volume) reveals systematic wealth transfer from emotional traders (takers) to patient market makers. Applies directly to LP/GP dynamics in VC.
The MAU Trap

AI Native VC
