Intro.
#Seed = One Card, Pre-Series A = Two, Series A = Three
In his book, Lee Taek-kyung compares early-stage investment decisions to a poker game. The core metaphor: the number of cards in your hand changes by round.
| Round | Cards Visible | What the VC Is Looking At |
|---|
| Seed | 1 | Team + hypothesis |
| Pre-Series A | 2 | Team + early user/MVP metrics |
| Series A | 3 | Team + PMF signals + early revenue |
| Series B | 4+ | Team + market share + unit economics + growth rate |
| Late stage | 5+ | Full financials, KPIs, and M&A comparables |
TIP
The point of the poker metaphor: the fewer cards you have, the harder it is to calculate odds — which makes the strength of that one or two cards decisive. At seed stage, the strength of a single card, the team, is what makes the bet.

#Defending Weaknesses vs. Leading With Strengths — a Strategy That Flips by Round
A deck built to pre-empt every weakness works at later stages — and costs you points at early ones. Modeled on the Lee Taek-kyung persona, the evaluation tone splits by round as follows.
| Round | Winning IR Strategy | Why |
|---|
| Seed | One or two clear strengths, pitched hard | 1 card — strength is decisive |
| Pre-Series A | Lead with strengths, acknowledge one key weakness | 2 cards — balance builds trust |
| Series A | Strengths + acknowledged weaknesses + a plan to address them | 3 cards — the tone of proven PMF |
| Series B+ | Defend weaknesses, manage risk | 4+ cards — the focus shifts to minimizing risk |
주의
"Early on, it's better to pitch your clear strengths hard. One or two reasons to invest beat a wall of defenses against weaknesses." (Lee Taek-kyung, Ch. 3 — Investor Mindset and Evaluation Criteria) — if your seed deck is full of "our weaknesses are X, Y, and Z, but here's how we cover all of them," the VC reads that as a weak single card.
03
#"One or Two Reasons to Invest" — the Core Structure of a Seed Deck
Seed decks that pass share one common structure: "here's the one or two reasons to invest" lands in under a minute. As long as that's clear, other weaknesses don't stop you from clearing the bar.
- The team card — the case that this is the team best qualified to solve this problem (background + execution track record)
- The pain card — the case that this is a problem customers genuinely want to pay to solve (one piece of evidence: interviews, an MVP, or payment data)
- The timing card — the case for "why now" (one shift in regulation, technology, or demographics)
체크
Even one strong card out of the three opens the door to clearing seed review. The riskiest deck is the one where all three are weak but the pitch insists it's "strong overall" — that's exactly the signal of a hand with no real card.
04
#FOMO — Even Investors Don't Know the Right Answer
Another truth about early-stage decisions: the investor doesn't know the right answer either. That's exactly why a deck that looks too perfect draws suspicion instead of confidence — it reads as a signal that something's being hidden.
TIP
"Investors get suspicious when something looks too perfect. FOMO — the opportunity cost of missing a startup that succeeds outweighs the cost of backing one that fails." (Lee Taek-kyung, Ch. 3 summary) — VCs place their bets on the feeling of "I'll regret missing this."
A deck that creates FOMO carries a tone like: "this market opens within five years, no question, and someone will own 50% of it — and we're the most likely candidate." A deck with one crystal-clear reason "you'll regret not betting on this" clears review at a higher rate than one that's simply hedged every risk.

#Five "Blurry Card" Patterns Common in Seed Decks
Here are five patterns the Lee Taek-kyung persona treats as an immediate red flag in a seed deck. All five share the same problem: no visible card.
- A SWOT chart with strengths, weaknesses, opportunities, and threats laid out in evenly weighted quadrants — it's unclear which card is actually strong
- A comparison table claiming to beat competitors on every dimension — a claim with zero trade-offs reads as a false signal
- Listing outside advisors as if they were full-time team members — masking a genuinely weak team card
- Heavy reliance on abstract adjectives ("innovative," "unrivaled," "world's best") — substituting adjectives for actual card strength
- "All of this gets solved once we have the funding" — a signal that defers the card itself to future capital
Summary.
#Self-Check Checklist
Six items to check whether your seed deck is actually built around the "one strong card" structure.
- Is "here's the one or two reasons to invest" spelled out on the very first page of your deck?
- Is at least one of the three cards — team, pain, or timing — backed by quantitative evidence (interviews, an MVP, or data)?
- Do you acknowledge one or two weaknesses or trade-offs? (A deck that tries to cover every angle costs you points.)
- Does your "why now" section answer with one specific shift — regulatory, technological, or demographic?
- Have you replaced abstract adjectives ("innovative," "unrivaled") with quantified claims?
- Is your full-time team given more emphasis than outside advisors?
