How to Find and Convert Customers on Hacker News
Hacker News has a technical, founder-heavy audience that actively evaluates new tools. The culture is completely different from Reddit — here's how to navigate it without embarrassing yourself or missing the opportunity.
HN Is Not Reddit: What Actually Matters Here
Hacker News is a community of engineers, founders, investors, and researchers — many of whom have built things themselves. The median reader has strong opinions about software, strong pattern-matching for marketing fluff, and a very low tolerance for self-promotion that isn't backed by something real.
This sounds intimidating, but it's actually an advantage for founders. HN readers are evaluating tools constantly. They will genuinely try your product if it's technically credible. And because they're often CTOs, engineering managers, or founders themselves, a single HN conversion can be worth more than a hundred Reddit clicks.
The rules are simple: be specific, be honest about limitations, skip the marketing language, and demonstrate that you actually understand the problem space. One concrete technical detail is worth more than three paragraphs of positioning copy.
The Three HN Thread Types That Matter
The Highest-Value Thread Type: Ask HN Tool Questions
"Ask HN: What tools do you use for X?" threads are the single most valuable thing to monitor on Hacker News if you're selling software. These threads are explicitly asking for product recommendations from people who have already decided to solve a problem. They're buying-intent in its purest form.
Examples of real high-value thread titles:
- ✓"Ask HN: What's your stack for monitoring SaaS metrics?"
- ✓"Ask HN: What do you use for customer support as a solo founder?"
- ✓"Ask HN: How do you find where people are talking about your product?"
- ✓"Ask HN: What tools do you use for outbound prospecting?"
- ✓"Ask HN: How are you handling community engagement at scale?"
These threads often hit the front page and stay there for 6–12 hours. Replies posted in the first 2 hours get the most upvotes because they accumulate engagement during peak visibility. A highly-upvoted comment in one of these threads can drive hundreds of visitors and dozens of signups in a single day.
How to Write an HN-Appropriate Reply
HN comment culture is different from anywhere else on the internet. Here's what works:
What wins on HN
- ✓Technical specificity — explain how something works, not just what it does
- ✓Honesty about tradeoffs and limitations — HN readers trust people who acknowledge their product's weaknesses
- ✓"This is interesting because..." framing — analyze before recommending
- ✓Disclosure of your affiliation (always say you built it, or work there)
- ✓Sharing what you tried before building your thing and why it didn't work
- ✓Concrete benchmarks or numbers that back up claims
What gets downvoted immediately
- ✓Marketing language: "powerful," "seamless," "next-generation," "game-changing"
- ✓Superlatives without evidence
- ✓Commenting purely to drop a link with no substance
- ✓Defending your product aggressively when someone criticizes it
- ✓Multiple top-level comments promoting your product in the same thread

Show HN: Your Best Shot at a Launch Spike
Show HN is the designated format for sharing something you built. It's the closest HN gets to a product launch venue, and a successful Show HN can drive 500–5,000 visitors in a single day depending on how well it resonates.
HN traffic peaks between 9am–2pm US Eastern time on weekdays, with Tuesday through Thursday being the strongest days. Post during this window and you'll have more active readers during the critical first 2–3 hours when rankings are determined.
"Show HN: Replyt – monitor Reddit/HN for high-intent threads and track replies to signups" performs better than "Show HN: AI-powered community outreach for founders." Describe what it does in plain language. HN readers will determine the value themselves.
A Show HN where the founder responds thoughtfully to every comment, including criticism, performs 2–3x better than one where comments go unanswered. Clear your calendar. Each response is a chance to demonstrate technical depth and build trust.
Genuinely. HN readers who take time to explain why they think your approach is wrong are giving you free product feedback. Acknowledge it, engage with the substance, and don't be defensive. Nothing builds HN credibility faster than handling criticism with intellectual honesty.
"Show HN: Replyt 6 months later — what we learned and where we are" is a legitimate follow-up post that performs well. The HN community appreciates transparency about what happened after the launch, especially if you share specific numbers.
The SEO Angle: HN Threads Rank on Google for Years
This is the most underrated reason to engage on Hacker News. HN threads — especially Ask HN and Show HN posts — frequently rank on the first page of Google for competitive terms. A thread titled "Ask HN: What's the best tool for monitoring Reddit?" might rank for "reddit monitoring tool" for three to five years after it was posted.
A comment posted in 2022 is still being read by every person who finds that thread through Google today. This is fundamentally different from Reddit, where most organic traffic dies after 48 hours. HN threads have backlinks, engagement signals, and domain authority from news.ycombinator.com — one of the most trusted domains on the internet.
Practically: before you reply to a thread, search Google for the thread's title or subject. If it already ranks on page 1 for a term relevant to your product, a reply is free, permanent placement in a high-traffic search result.
