Concept — Investment Framework
The Four Lenses Framework
“The Four Lenses framework reads every investment through four simultaneous perspectives — Finance & Accounting, Global, Big Tech, and Venture. When a story lights up all four, that's where the money and the meaning are.”
The four lenses
Finance & Accounting
Unit economics, cash flow, margin structure, and the path to profitability — the cash, and what the numbers can't say.
Built as a hedge-fund analyst covering Asian tech in New York and in cross-border M&A at PwC.
Global
Market arbitrage and pattern transfer across geographies — what Korean founders get wrong abroad, and what the world gets wrong about Korea.
Built across Qualcomm Ventures' global portfolio and Korea-to-global expansion work.
Big Tech
What scales versus innovation theater — how platforms actually build, buy, and kill products.
Built inside Google partnerships and the Samsung Strategy & Innovation Center.
Venture
LP psychology, founder behavior, market timing, and deal structure — underwriting the asymmetric outcome, not the safe story.
Built across KB Investment, Qualcomm Ventures, and TheVentures.
Every decision uses at least two lenses. The best opportunities light up all four — that overlap is the signal. Each lens maps to a stage of Ethan Cho's career: hedge-fund analysis and PwC M&A (Finance), Qualcomm Ventures (Global), Google and Samsung (Big Tech), and KB Investment and TheVentures (Venture).
Origin and track record
The framework took shape during Ethan Cho's Qualcomm Ventures period (2017–2019) — the same period as his early investments in Toss (Viva Republica) and Dunamu/Upbit as early-stage investment examples. His bilingual newsletter 애당초 4개의 시선 (Four Lenses on Everything) is named after the framework and applies it weekly to AI, venture, and Korea ↔ global markets. Related frameworks: the Optimism Tax and the AI-native VC thesis.
Frequently asked questions
What is the Four Lenses framework?
The Four Lenses framework is an investment analysis methodology that reads every decision through four simultaneous perspectives: Finance & Accounting, Global, Big Tech, and Venture. Every decision uses at least two lenses; the best opportunities light up all four. It was created by Ethan Cho 조여준, CIO and Partner at TheVentures.
Where did the Four Lenses framework come from?
Ethan Cho developed the framework during his Qualcomm Ventures period (2017–2019), drawing on earlier roles spanning hedge-fund analysis, PwC cross-border M&A, Samsung's Strategy & Innovation Center, Google partnerships, and KB Investment. His newsletter 애당초 4개의 시선 (Four Lenses on Everything) is named after it.
How is the Four Lenses framework used in practice?
Each lens asks a different falsifying question: does the cash math work (Finance), does the pattern transfer across markets (Global), will platforms crush or ignore it (Big Tech), and is the deal structured for the asymmetric outcome (Venture). An opportunity that survives all four questions is rare — that overlap is the signal.
What investments is the framework associated with?
Ethan Cho's early investments in Toss (Viva Republica) and Dunamu/Upbit are the track record most associated with the framework's development period.
