# Startup Projects

## 매 한 줄
> **"매 idea → MVP → PMF — 매 minimum viable iteration"**. Startup projects 는 매 small team 이 short cycle 로 product 의 market fit 을 찾는 의 process — 매 2026 의 AI-augmented (Claude Code, v0, Cursor) 시대 에 single founder 가 weeks 의 launch 가능. 매 distribution 이 새로운 moat.

## 매 핵심

### 매 stage
- **Idea**: 매 problem 검증 (5 사용자 interview > 50 의 survey).
- **MVP**: 매 1~4 주 build — 매 핵심 1 기능 만.
- **Launch**: 매 Product Hunt / Hacker News / X / TikTok.
- **PMF (Product-Market Fit)**: 매 retention 곡선 이 flatten + organic growth.
- **Scale**: 매 paid acquisition + team hire.

### 매 modern stack (2026)
- **Build**: Next.js 15 + Supabase / Convex + Vercel / Cloudflare.
- **AI**: Claude Opus 4.7 / GPT-5 (logic), FLUX (image), ElevenLabs (voice).
- **Code agent**: Claude Code, Cursor, v0.
- **Payments**: Stripe / LemonSqueezy / Polar.
- **Analytics**: PostHog / Plausible.
- **Email**: Resend / Loops.

### 매 응용 (project type)
1. **Vertical AI SaaS** — 매 niche workflow + LLM (legal review, medical scribe).
2. **AI wrapper + moat** — 매 GPT API + proprietary data / community.
3. **Dev tool** — 매 OSS + cloud (Linear, Cursor, Resend).
4. **Consumer AI** — 매 chat / voice / image 의 mass app.
5. **Marketplace** — 매 supply / demand 의 two-sided.

## 💻 패턴

### Idea validation (LLM-assisted user interview)
```typescript
// generate interview script via LLM, then run 5 calls
import Anthropic from "@anthropic-ai/sdk";
const a = new Anthropic();
const script = await a.messages.create({
  model: "claude-opus-4-7-20260101",
  max_tokens: 1000,
  messages: [{ role: "user", content: `Generate 7 Mom-Test questions for: ${idea}` }],
});
```

### MVP scaffold (Next.js 15 + Supabase)
```bash
npx create-next-app@latest myapp --typescript --tailwind --app
cd myapp
npm install @supabase/supabase-js @supabase/ssr stripe @anthropic-ai/sdk
npx supabase init && npx supabase start
```

### Stripe checkout (3 lines of magic)
```typescript
const session = await stripe.checkout.sessions.create({
  mode: "subscription",
  line_items: [{ price: "price_xxx", quantity: 1 }],
  success_url: `${origin}/success?session_id={CHECKOUT_SESSION_ID}`,
  cancel_url: `${origin}/pricing`,
});
return Response.redirect(session.url!);
```

### Waitlist (Resend + KV)
```typescript
export async function POST(req: Request) {
  const { email } = await req.json();
  await kv.sadd("waitlist", email);
  await resend.emails.send({
    from: "founder@app.dev",
    to: email,
    subject: "You are on the list",
    text: "Thanks. We'll email when ready.",
  });
  return Response.json({ ok: true });
}
```

### Product Hunt launch checklist (programmatic)
```typescript
const checklist = [
  "Tagline ≤ 60 chars",
  "Gallery: 3 GIFs + 4 screenshots",
  "First comment with maker story",
  "Notify 50 supporters at 12:01 AM PT",
  "Reply to every comment within 1 hour",
];
```

### Retention cohort (PostHog SQL)
```sql
SELECT
  date_trunc('week', signup_date) AS cohort,
  COUNT(DISTINCT CASE WHEN active_week_1 THEN user_id END)::float
    / COUNT(DISTINCT user_id) AS week_1_retention
FROM users GROUP BY 1 ORDER BY 1;
```

### LLM cost guard (production)
```typescript
const usage = await kv.incrby(`tokens:${userId}:${day}`, tokensUsed);
if (usage > plan.dailyTokenCap) throw new Error("Daily cap exceeded — upgrade");
```

## 매 결정 기준
| 상황 | Approach |
|---|---|
| Solo + nights/weekends | 1-feature MVP, no auth, free tier only |
| 2 cofounder + 6mo runway | vertical AI SaaS, Stripe day 1 |
| Need fast ship | Next.js + Supabase + Vercel |
| B2B SaaS | LinkedIn outbound + demo-driven |
| Consumer | TikTok / X 의 daily content + waitlist |
| Dev tool | OSS-first + GitHub stars 의 social proof |

**기본값**: Next.js 15 + Supabase + Stripe + Resend + PostHog. 매 launch 는 Product Hunt + HN + 5 communities.

## 🔗 Graph
- 응용: [[SaaS]]
- Adjacent: [[Lean-Startup]]

## 🤖 LLM 활용
**언제**: idea validation script, landing copy, MVP scaffolding (Claude Code), launch tweet drafts, customer support drafts.
**언제 X**: financial / legal / hiring 의 final decisions — 매 expert 의 review 필수.

## ❌ 안티패턴
- **Build before talk**: 6 month 의 stealth 개발 후 의 zero user. 매 5 user interview 먼저.
- **Feature creep MVP**: 매 1 feature 의 sharp 의 vs 의 5 feature 의 mediocre.
- **Stealth mode**: build in public 의 distribution moat 포기.
- **No pricing day 1**: free 만 하면 willingness-to-pay 검증 X.
- **Founder-market fit 무시**: 매 unfamiliar domain 의 6mo 의 grind 후 burnout.
- **AI wrapper 의 moat 부재**: GPT-5 prompt 만 의 product 는 moat 0. Data / workflow / community moat 필요.

## 🧪 검증 / 중복
- Verified (YC essays, The Mom Test by Rob Fitzpatrick, Indie Hackers community 2025-2026, Lenny's Newsletter).
- 신뢰도 A.
