Show HN early-morning seeded engagement launch
Post a Show HN on Tuesday through Thursday between 7-9 AM EST and have 5-10 real supporters upvote and leave genuine comments in the first hour to escape the new page and reach the front page where organic traffic takes over.
Why this can grow a startup
Hacker News ranks posts by early engagement velocity. A small cluster of authentic upvotes and comments in the first 60 minutes pushes the post off the new page and onto the front page, where thousands of technically-minded early adopters browse daily. Once on the front page, organic traffic compounds because HN readers tend to share interesting Show HN posts on X, Reddit, and Slack. The cost is zero and the audience quality is exceptionally high for developer and B2B SaaS tools.
Company example
Reddit founder (r/SaaS, March 2026) documented getting 500 first users with this exact playbook; separately, a YC-backed startup (Indie Hackers, 2026) reported that half of its 8,000-person waitlist came from a single Hacker News post, vastly outperforming YC reposts and other channels.

When to use it
Use this when Communities, Hacker News is relevant to pre-launch and you can run a bounded test with a free budget.
When not to use it
Do not use it as a substitute for customer evidence, a clear owner, or a measurable stop condition. Local platform rules and market behavior still need checking.
Founder checklist
- Read reddit.com and identify what is directly supported.
- Choose one channel context: Communities, Hacker News.
- Define the test around one observable customer behavior.
- Set an owner, evidence window, and stop condition before launch.
