⚠️ Distinguish B2B from 2C
This skill defaults to being oriented toward dev / open source / B2B SaaS. If the product is 2C consumer goods / education / apps / games: replace the core metrics with D1/D7/D30 retention, activation rate, and viral coefficient K (not MRR/CAC/LTV); replace cold-start channels with vertical communities / short videos / vertical KOLs (not PH/HN/LinkedIn). For the complete 2C adaptation guide + public channel data for each country, see → gingiris-seo-geo/references/2c-adaptation.md。

Your launch day is ONE shot. This playbook gives you an hour-by-hour execution plan so nothing falls through the cracks. From T-minus-12-hours prep to the 72-hour post-launch sprint.
What You'll Learn
- T-12h: Final checks (servers, links, payment, copy)
- Hour 0: Coordinated channel activation sequence
- Hours 1-6: Real-time monitoring and engagement tactics
- Hours 6-24: Second-wave amplification
- 72-hour post-launch momentum playbook
- Crisis management (site down, negative feedback, competitor attacks)
Who This Is For
- Founders with a launch date already set
- Teams who have the product ready but need execution confidence
- Anyone who's been burned by a disorganized launch before
Traffic Engineering for Launch Day (2026 field addendum)
Plan the day as arithmetic, not vibes
Fix a total-visits target, then reverse-engineer per-channel quotas — each with its own UTM short link and a named owner. Anonymized reference (an AI Agent product, late 2025): a 500K-visit launch day was assembled as ~400K from 40 creator quote-tweets, plus ~20K each from Reddit threads, geo-targeted YouTube ads, and messaging-group distribution. Final tally: ~800 signups at $6.25 per registration. The lesson cuts both ways — traffic is buildable to spec; conversion is the bottleneck you can't buy.
Sequencing patterns worth stealing
- Split objectives across two days: half your amplifiers push the website on day one, the other half push the leaderboard (PH, etc.) on day two. One day, one goal — otherwise the streams dilute each other.
- Burst window: get 50–100 creators publishing inside the same 24–48h. Algorithms reward density, not totals.
- Platform relay (from the Manus/Devin post-mortems): days 0–3, X/Twitter builds the conversation → days 3–10, YouTube and newsletters consolidate it → day 10+, Reddit/HN carry the long tail. For a big launch, concentrate ~80% of spend on the same day.
Hacker News: the 30-minute verdict
The front page is decided in the first half hour — roughly 30 points and 10 comments, posted during the US morning window. Flat at minute 40 = done. Bring 2–3 prepared angles (a "Show" post, an open-source-alternative link, a how-it-works writeup) rather than one perfect post, and translate the winner for regional dev forums — one text, two communities.
Readiness gate
Don't set the date until at least 10 external developers are satisfied and still actively using the product. Pre-launch time split: 60% talking to users, 40% preparing the launch — start asset prep once the product hits "60 points," copy first, visuals later.
