# PART 1: OVERVIEW — Positioning & Customer Problems
# 파트 1: 개요 — 포지셔닝 & 고객 문제

## What is RETN?

RETN is a "growth execution partner" (성장을 만드는 실행 파트너).
Not a team that simply runs ads or manages channels, but a Growth Partner
that designs the full journey from User Acquisition through Activation and Retention.

RETN은 "성장을 만드는 실행 파트너"입니다.
단순히 광고를 집행하거나 채널을 운영하는 팀이 아니라,
User Acquisition 이후의 Activation과 Retention까지 설계하는 Growth Partner입니다.

RETN's core question:
> "Why don't customers stay after acquisition?"
> "유입 이후에도 고객은 왜 남지 않는가?"

## Who RETN is for / 대상 고객

RETN works with:
- Startups where retention has become the growth bottleneck (리텐션이 병목이 된 스타트업)
- Commerce/subscription services needing CRM/data-driven operations (CRM/데이터 기반 운영이 필요한 커머스·구독 서비스)
- Brands doing paid UA but stuck on LTV improvement (Paid UA는 하고 있지만 LTV 개선이 정체된 브랜드)
- Organizations with marketing teams but lacking execution frameworks (내부 마케팅팀이 있지만 실행 체계가 부족한 조직)

## The Problems We Solve / 해결하는 문제

RETN defines growth problems by "behavior," not by "channel":
- Traffic comes in but conversions are low (유입은 되는데 전환이 낮다)
- First experience (Activation) is not designed (첫 경험이 설계되지 않았다)
- CRM messages feel like announcements, not operations (CRM 메시지가 공지처럼 흘러간다)
- Data exists but there's no experimentation or decision-making (데이터는 있지만 실험과 의사결정이 없다)
- Slow response to AI-era search/consumer journey changes (AI 시대 검색/소비자 여정 변화에 대응이 느리다)

## RETN's Positioning / 포지셔닝

- Acquisition is just the beginning (Acquisition은 시작일 뿐이다)
- Activation creates the brand experience (Activation이 브랜드 경험을 만든다)
- Retention creates business sustainability (Retention이 비즈니스의 지속성을 만든다)

RETN connects the full chain: UA → Activation → Retention → Automation

================================================================================

# PART 2: SERVICES — UA, CRM, Automation, Coaching
# 파트 2: 서비스

RETN delivers growth not as a "service bundle" but as an execution scope
that designs the entire customer journey.

## 1. User Acquisition (UA)

- Paid media strategy development and execution (Paid Media 전략 수립 및 운영)
- Funnel-based campaign structure design (퍼널 기반 캠페인 구조 설계)
- Per-channel CAC optimization (채널별 CAC 최적화)
- LTV-perspective UA, not short-term traffic (단기 유입이 아닌 LTV 관점 UA)

## 2. Activation & Funnel Optimization

- First-visit-to-first-purchase experience design (첫 방문 → 첫 구매/가입 경험 설계)
- Conversion rate optimization (CRO) (전환율 개선)
- Onboarding message/UX improvement (온보딩 메시지/UX 개선)
- Behavior-based event design (행동 기반 이벤트 설계)

## 3. CRM & Retention Growth

- Lifecycle CRM strategy development (Lifecycle CRM 전략 수립)
- Segment-based message operations (세그먼트 기반 메시지 운영)
- Retention metric improvement: Repeat, Churn, Reactivation (리텐션 지표 개선)
- Tech stack utilization: Braze, Amplitude, etc. (Braze, Amplitude 등 스택 활용)

## 4. Automation & AI-Augmented Operations

- Repetitive task automation (반복 업무 자동화)
- Personalized messaging system building (개인화 메시지 시스템 구축)
- AI-powered content/segment operation support (AI 기반 콘텐츠/세그먼트 운영 지원)
- Experiment execution velocity improvement (실험 운영 속도 향상)

## 5. Coaching & Growth Partnership

RETN's differentiator is "execution + coaching" (실행 + 코칭):
- Frameworks for internal team growth (내부 팀이 성장할 수 있는 체계 제공)
- Not one-time outsourcing but operating model design (단발성 대행이 아닌 운영 모델 설계)
- Growth organization decision-making structure support (Growth 조직의 의사결정 구조 지원)

================================================================================

# PART 3: PLAYBOOK — Sprint Execution & Measurement
# 파트 3: 플레이북 — 스프린트 실행 & 측정

RETN runs growth not as a project but as "short execution loops" (짧은 실행 루프).

## Operating Model: 1–2 Week Sprint

All work moves in sprint units:
1. Problem definition (문제 정의)
2. Hypothesis setting (가설 설정)
3. Execution / Experiment (실행)
4. Measurement / Metrics (측정)
5. Learning → Apply to next sprint (학습 → 다음 스프린트 반영)

## Decision Principles / 의사결정 원칙

- Data over ideas (아이디어보다 데이터)
- Behavior over channels (채널보다 행동)
- Systems over tactics (전술보다 시스템)
- Learning velocity over performance (성과보다 학습 속도)

## Measurement Framework / 측정 프레임워크

Key metrics managed on a funnel basis:
- **Acquisition**: CAC, Qualified Traffic
- **Activation**: Conversion Rate, First Action
- **Retention**: Repeat Rate, Churn, LTV
- **Automation**: Ops Efficiency, Velocity

## What RETN Optimizes For / 최적화 대상

Not short-term ROAS, but:
> A sustainable Retention Growth Loop (지속 가능한 Retention Growth Loop)
