Joining Douyin: Early Days and First Impressions

Campus Recruitment at ByteDance

• Formal approval: 2016
• Gaining traction: Around July–August 2017
• Internship start: Beginning of 2018

At that time, ByteDance was still largely seen as “Toutiao” — with a somewhat rustic brand image.

Beichuan discovered an opening for Social Product Manager, and after several cross-team interviews, realized it was for Douyin.

> Fun fact: He had never heard of Douyin before that last interview.

Douyin's Early Growth Waves

• Second half of 2017:
• “Million Hero” (HQ Trivia-style game) embedded into multiple ByteDance products.
• University students switched from Toutiao to Douyin due to brand appeal.
• 2018 Lunar New Year:
• Douyin gained Huoshan’s Spring Festival Gala sponsorship slot by chance.
• Traffic doubled during the holiday — first major internal recognition of Douyin’s potential.
• 2018–2019:
• Initiatives to accelerate growth.
• Douyin’s DAU overtook Kuaishou.

---

Growth Phases (2017–2020)

• 2017–2018: Scaling-up phase.
• 2018–2019: No.1 in short video, surpassing Kuaishou.
• 2019–2020: Became China’s largest DAU product after WeChat.
• Post-2020: Shifted focus to e-commerce and local services for monetization.

> Strategic origin: Zhang Yiming identified 0–1 min short content as a large untapped space compared to long-form (movies), mid-form (Bilibili), and text/pictures.

---

Breaking Through the Ceiling

At the time, even optimistic forecasts saw Douyin capped at ~12M DAU.

WeChat’s DAU was seen as the ultimate ceiling.

To break this, Douyin explored social features akin to Instagram or WeChat Moments — aiming to boost retention and interaction.

> Outcome: Social experiments largely failed — illustrating cultural and structural reasons ByteDance struggled with people-centric ecosystems.

---

Tone and Operational Taste

• No traffic funnel from Toutiao → independent growth strategy.
• Distinct brand aesthetics: All-black UI, logo, positioning.
• Curated content: Editorial control before algorithm scale-up.

This combination attracted a younger audience, differentiated from competitors like Huoshan and Kuaishou.

---

Product Mechanics: Single Column vs Double Column

• Single column feed:
• Higher distribution efficiency.
• Better for content generalization (“泛化”).
• Double column feed (Kuaishou, Xiaohongshu, Bilibili):
• More even traffic distribution.
• Better for community interaction.
• Higher amateur creator participation.

Debates inside Douyin were intense, but growth metrics favored single column, so it was retained.

---

“Brain-Off” Content Positioning

Douyin competes with gaming for idle user time.

The “brain-off” nature — easy to consume, habit-forming — drove higher ceilings.

Recommendation systems reinforced this by pushing more of the relaxing content people opened without thinking.

---

Spring Festival Traffic War (2020)

Objective: Counter Kuaishou’s exclusive Gala sponsorship.

Tactics:

• Red packet giveaway: if Kuaishou offered ¥1B, Douyin offered ¥2B.
• Cross-app traffic funneling from six sibling apps into Douyin via “Douyin card” mechanic.

Results:

• Peak DAU: 470M during Gala night.
• Positive LTV — many new users retained during the pandemic.
• Marked the start of Douyin’s explosive growth phase.

---

ByteDance’s Organizational Culture

Flat Structure & Demystification

• No public titles; accessible leadership.
• Direct communication across hierarchy.
• Encouraged young hires to take responsibility early.
• Culture fostered ambition and ownership.

> This culture is seen as ByteDance’s core competitive advantage — now diluted as the company scales and hires externally.

---

Pursuit of the Extreme

ByteDance’s DNA: Not incremental growth — drive for 2×, 5× outcomes.

This cognitive push often leads to strategic innovation and category disruption.

---

From Douyin to AI Entrepreneurship

After leaving ByteDance, Beichuan founded Lessie AI — a People Search AI Agent designed to help find and connect with targeted individuals (e.g., KOLs, clients, candidates) more efficiently than traditional SaaS tools.

---

Lessons for Entrepreneurs

• Big company vs startup:
• Corporates hone problem-solving.
• Startups force resource allocation & strategic choices.
• Avoid false busyness:
• Focus on tasks that move the business forward (product definition, hiring key roles, budget planning).
• Window of opportunity:
• Scale before incumbents engage.
• Define entry point, PMF, and growth strategy clearly.

---

Parallels in Today’s Multi-Platform Era

Modern creators face similar scaling challenges.

Platforms like AiToEarn integrate:

• AI content generation
• Cross-platform publishing (Douyin, Kuaishou, WeChat, Bilibili, Xiaohongshu, YouTube, Instagram, Twitter/X, etc.)
• Analytics & AI model rankings

This echoes the deliberate, resource-coordinated growth strategies Douyin used — but made accessible to individual creators.

---

Key Takeaways:

• Independent early growth can be slower, but sets the right path.
• A distinct brand tone matters as much as algorithms.
• Flat organizational culture can accelerate young talent’s rise.
• “Pursuit of the extreme” thinking can reframe what’s possible.
• Tools that integrate creation + distribution + analytics help creators capture multi-platform opportunities before competitors move in.
