Regional Launch Timing

Timing the launch for each region — when to post on Product Hunt (US midnight), when to post on Juejin (China morning), when to email the Japanese waitlist — to maximize each region's spike.

Why

A single global launch time (e.g., 12:01am PST) optimizes for the US audience but posts at 4pm in China (when developers are finishing work, not browsing) and 5pm in Japan (when they're commuting, not voting). Each region has a different optimal launch window: Product Hunt voting peaks at US morning (9am-12pm PST), Juejin upvoting peaks at China morning (9am-12pm CST), Qiita engagement peaks at Japan evening (8pm-11pm JST). Staggering the launch by region — PH at 12:01am PST, Juejin at 9am CST (the next day), Qiita at 8pm JST — gives each region its own spike at its optimal time, and the spikes compound: the US PH spike generates social proof that the China Juejin post rides 16 hours later. A single global time gets one spike; regional timing gets 3-5 spikes that compound.

When

Plan regional timing 1 week before launch; execute in sequence (US first, then Asia 12-16h later, then Europe 4-8h after Asia); monitor each region's spike in real-time.

How

1. Map each region's optimal launch window: US (Product Hunt 12:01am PST, HN 12:15am, Twitter 12:30am), China (Juejin 9am CST, V2EX 10am, WeChat groups 11am), Japan (Qiita 8pm JST, Zenn 9pm, Twitter JP 10pm), Korea (OKKY 9am KST, Twitter KR 10am), Europe (LinkedIn 8am CET, dev.to 9am, Twitter EU 10am)
2. Sequence by region: US first (T+0, 12:01am PST) → China second (T+16h, 9am CST next day) → Japan third (T+20h, 8pm JST) → Korea fourth (T+24h, 9am KST) → Europe fifth (T+32h, 8am CET)
3. For each region, prepare the native content: China (Juejin post in Chinese, references 掘金 community), Japan (Qiita post in Japanese, references Qiita), Europe (LinkedIn post in English, references European dev communities)
4. On launch day, execute US first and monitor for 4 hours; when the US spike peaks (around 9am PST), prepare the China content (add US social proof: 'trending on Product Hunt')
5. T+16h: post to Juejin and V2EX in Chinese; the post references the US PH success ('623 upvotes on Product Hunt in 16 hours') — this social proof boosts China engagement
6. T+20h: post to Qiita in Japanese; reference both US and China success
7. T+24h: post to OKKY in Korean; reference US, China, Japan success
8. T+32h: post to LinkedIn and dev.to for Europe; reference global momentum
9. Monitor each region's spike (upvotes, signups) and compile a regional report at T+48h

## Regional schedule
| Region | Channel    | Time (local) | T+offset | Content lang |
|--------|------------|--------------|----------|--------------|
| US     | Product Hunt | 12:01am PST | T+0      | English      |
| US     | Hacker News  | 12:15am PST | T+15min  | English      |
| US     | Twitter      | 12:30am PST | T+30min  | English      |
| China  | Juejin       | 09:00am CST | T+16h    | Chinese      |
| China  | V2EX         | 10:00am CST | T+17h    | Chinese      |
| Japan  | Qiita        | 08:00pm JST | T+20h    | Japanese     |
| Korea  | OKKY         | 09:00am KST | T+24h    | Korean       |
| Europe | LinkedIn     | 08:00am CET | T+32h    | English      |
| Europe | dev.to       | 09:00am CET | T+33h    | English      |

## Social proof chain
T+0:   US PH launch (no prior proof)
T+16h: China Juejin — "623 upvotes on Product Hunt in 16h"
T+20h: Japan Qiita — "#1 on Product Hunt, 1,200 stars on GitHub"
T+24h: Korea OKKY — "trending globally, 3,127 signups"
T+32h: Europe LinkedIn — "4,892 signups across 47 countries"

## T+48h regional results
US:     1,892 signups (PH 60% + HN 24% + Twitter 10%)
China:  892 signups (Juejin 70% + V2EX 20% + WeChat 10%)
Japan:  423 signups (Qiita 80% + Zenn 15% + Twitter 5%)
Korea:  234 signups (OKKY 70% + Twitter 30%)
Europe: 686 signups (LinkedIn 50% + dev.to 30% + Twitter 20%)
Total:  4,127 signups (32% more than US-only launch)

Common Problems

  • ⚠Launching globally at one time (12:01am PST) — this is optimal for the US but posts at 4pm in China (developers are finishing work) and 5pm in Japan (commuting); each region gets a suboptimal spike; staggering by 12-16h gives each region its optimal window.
  • ⚠Posting to Chinese channels in English — Juejin and V2EX are Chinese-language communities; an English post gets 1/10 the engagement of a Chinese post; translate the content or skip the channel.
  • ⚠No social proof chain between regions — the China post doesn't mention the US PH success, so it starts cold; referencing '623 upvotes on Product Hunt in 16h' gives the China post instant credibility and boosts engagement 2-3x.
  • ⚠Forgetting Korea and Europe entirely — Korea has 500K developers and OKKY is the dominant dev community; Europe has 3M developers and LinkedIn/dev.to are the main channels; skipping these regions leaves 3,500 potential signups on the table.

Best Practices

  • ✓Stagger by region with 12-16h gaps — US first (rides PH 24h window), then Asia (rides US social proof), then Europe (rides global momentum); each region gets its optimal local time AND the prior region's social proof.
  • ✓Post in the region's native language — a Chinese post on Juejin gets 10x the engagement of an English post; a Japanese post on Qiita gets 8x; the translation cost ($50-100/post) pays for itself in the first 10 signups.
  • ✓Chain social proof between regions — each region's post references the prior regions' success ('#1 on Product Hunt, 1,200 GitHub stars, 3,127 signups'); this gives cold-start regions instant credibility and boosts engagement 2-3x.
  • ✓Include Korea (OKKY) and Europe (LinkedIn, dev.to) — these regions are often forgotten but have 3.5M developers combined; a 30-minute post to each brings 500-900 signups that you'd otherwise leave to competitors.
