How to Use Hacker News for Marketing: The Founder's Guide

Hacker News marketing works through two channels: Show HN posts that announce your product to a technical audience, and organic participation in relevant discussions where your product is genuinely useful. A successful Show HN can drive 500 to 5,000 visitors in a single day. The prerequisite is understanding that HN has a distinct culture — self-promotion without substance gets flagged, but genuine contributions get rewarded with outsized reach.

Why Hacker News Is Different From Every Other Marketing Channel

Most marketing channels reward volume. Post more, reach more people. Hacker News is the opposite. It rewards depth, authenticity, and technical substance. The community — primarily developers, founders, and technically-minded people — is highly allergic to anything that reads like marketing copy.

This makes HN one of the most difficult platforms to market on. It also makes it one of the most valuable. The audience is your ICP if you are building a developer tool, a SaaS product, or anything targeting technically sophisticated users. A post that lands on the front page exposes your product to tens of thousands of exactly the right people.

The critical rule before doing anything on Hacker News: read it. Spend one to two weeks reading the front page, reading the comments on posts about products similar to yours, and understanding what the community responds to. You cannot fake your way through HN culture — and you should not try.

The Two Types of HN Posts That Drive Traction

Show HN

A Show HN post is explicitly for sharing something you have built. It is the most direct way to announce a product on Hacker News.

The format is rigid: your title must start with "Show HN:" followed by a brief description of what you built. The community expects you to be the founder or a core contributor — not a marketer promoting someone else's product.

What makes a Show HN succeed:

The title is specific. "Show HN: I built a marketing agent that runs SEO and Reddit from your website URL" outperforms "Show HN: AI marketing tool for startups." Specific beats vague every time.
The description in the comments is honest. Your first comment should explain what you built, why you built it, what stage it is at, and what feedback you are looking for. Founders who are candid about what their product cannot do yet build more trust than those who oversell.
The product actually works. HN users will click through, try it, and report back in the comments. A product that is half-finished or has obvious bugs will generate brutal feedback publicly.
You respond to every comment. Active engagement from the founder is rewarded. Ignoring your own Show HN thread signals disinterest and kills momentum. What kills a Show HN:
Marketing language in the title ("Revolutionary," "Game-changing," "The future of")
A landing page that does not let users try the product immediately
Not responding to comments
Posting at the wrong time (peak HN hours are 9am to noon Eastern — US weekday mornings)

Ask HN

Ask HN posts are questions posed to the community. They drive engagement rather than direct product traffic, but done strategically they build credibility and surface your product naturally.

Examples of Ask HN posts that work for founders:

"Ask HN: What tools do you use to manage marketing as a solo founder?"
"Ask HN: Has anyone had success with AI-generated content for SEO?"
"Ask HN: How do you handle distribution when you have no marketing budget?" These posts invite discussion rather than promoting a product. If your product is genuinely relevant to the discussion and you mention it transparently ("I built something for this, happy to share"), it lands very differently than "use my product."

How to Write a Show HN Post That Gets Traction

Study the Show HN posts that have reached the front page in your category. Go to news.ycombinator.com/show and filter by top posts. For each successful post, note: the title structure, what the first comment said, how the founder responded to feedback, and what drove upvotes in the comments.

Title formula that consistently works:

Show HN: [What you built] that [what it does for a specific person]

Examples:

"Show HN: Okara — a marketing agent that runs SEO, Reddit, and LinkedIn from your website URL"
"Show HN: I built an AI tool that finds Hacker News discussions where your product belongs"
"Show HN: A $99/mo marketing agent that replaces the content writer, SEO consultant, and community manager" The best titles include a specific outcome or a specific person. "Marketing agent for founders who have no marketing budget" is better than "AI marketing platform."

First comment structure:

Your first comment is where you tell the full story. It should include:

What problem you are solving and why you care about it personally
What the product does in plain language (no buzzwords)
What stage it is at (beta, launched, paying customers — be honest)
What you are looking for from the community (feedback on X, or just sharing what you built)
A brief technical note about how it works if relevant (HN readers appreciate this) Keep it under 300 words. If you cannot explain it in 300 words, the product is not clear enough yet.

What to do in the first hour after posting:

Monitor comments in real time
Respond to every comment, especially critical ones
Engage substantively — not "thanks for the feedback!" but actually addressing the point raised
If someone points out a bug or a flaw, acknowledge it and explain whether you plan to fix it
Upvote comments that are useful (this is not gaming — it is normal participation)

Participating in HN Discussions Without a Show HN Post

Show HN is not the only way to get HN traction. Regular participation in relevant discussions drives visibility over time and builds credibility that makes future Show HN posts more likely to succeed.

Finding the right threads:

Search HN for topics adjacent to your product. hn.algolia.com lets you search all HN posts and comments with date filters. Look for:

Posts about the problem your product solves
Posts asking for tool recommendations in your category
Posts about adjacent topics where your product would be a natural mention How to contribute without being promotional:

The rule is simple: lead with value, mention the product when it is directly relevant, and be transparent.

A comment that works: "I've been running into this exact problem. A few things that helped: [genuine advice]. I also built something for this exact use case — [product name] — if that's relevant to your situation."

A comment that gets flagged: "[Product name] solves this! Check it out at [URL]."

The difference is the ratio of value to promotion. The community will accept a product mention if it comes after a substantive contribution. A bare link drops with no context will be ignored or flagged.

Building an account before your launch:

HN accounts with no comment history look like spam accounts. If you are planning a Show HN post, start participating in discussions a few weeks in advance. Make substantive comments in threads about your industry. This is not gaming the system — it is being a real member of the community.

What Happens When It Works

A Show HN post that reaches the front page can drive between 500 and 10,000 visitors in a single day, depending on your position and how long you hold it. The visitors are almost entirely the technical, founder, and developer audience that represents your ICP.

The effects beyond day one:

HN posts are indexed by Google and rank for years. A successful Show HN is a long-term SEO asset.
HN is one of the sources LLMs cite when forming answers about tools and products. Getting mentioned in HN discussions contributes to your GEO visibility.
Journalists and newsletters monitor HN for product launches. A front-page Show HN often generates secondary press coverage without any outreach.
The feedback in the comments, even when harsh, is some of the highest-quality product feedback available anywhere. Okara launched with a viral post that generated 13 million views. The distribution did not start there — it started with the HN community and Reddit, which seeded the initial amplification. The HN agent writes Show HN variations in a technical, builder's voice for exactly this reason. The channel is high-effort, high-reward, and completely inaccessible to mass marketing tactics — which is what makes it so valuable.

Common Mistakes Founders Make on HN

Posting too early. A Show HN with a product that is not yet usable generates negative feedback that follows your product on HN forever. Posts are indexed. Launch when the product is solid enough for strangers to use without hand-holding.

Marketing language in the title. Anything that sounds like a press release will be downvoted immediately. Write the title the way you would explain it to a developer friend, not the way a PR firm would write it.

Ignoring critical comments. The worst thing you can do is not respond to a pointed question or criticism. The community notices. Thoughtful engagement with criticism often generates more upvotes than the post itself.

Not timing the post correctly. Post between 9am and noon Eastern time on a weekday. Weekend posts and evening posts get less traffic, which means fewer upvotes in the critical first hour, which means lower front-page probability.

Posting multiple times quickly. If your Show HN does not get traction, wait at least a few weeks before reposting with a meaningfully different angle. Repeated posts from the same account look desperate and get flagged.

Frequently Asked Questions

What is a Show HN post? A Show HN post is a Hacker News submission where founders share something they have built. It must start with "Show HN:" and is intended for announcing products, tools, or projects to the HN community. Successful Show HN posts can reach the front page and drive thousands of visitors in a single day.

Is it okay to promote your product on Hacker News? Transparent promotion tied to genuine participation is accepted. Pure promotional posts without substance are downvoted and flagged. The community accepts product mentions when they follow a substantive contribution or when the product is shared honestly via a Show HN post with a real founder explaining what they built.

When is the best time to post on Hacker News? Between 9am and noon Eastern time on weekdays. This is when HN traffic and voting activity peaks. Posts that gain traction in the first two hours have the highest probability of reaching the front page.

How many upvotes does it take to reach the front page? There is no fixed number — the algorithm weighs upvotes, time, and velocity. A post that gets 20 upvotes in the first 30 minutes has a better front-page probability than a post that gets 20 upvotes over two hours. Early momentum is more important than total count.

Can you use AI to write Show HN posts? AI can help draft Show HN variations, but the voice should sound like a real founder, not a marketing brief. HN readers are experienced at identifying generic AI output. The best approach is to use AI to generate multiple angle options and then rewrite the one that feels most authentic in your own voice. Okara's HN agent writes variations based on your product context and past viral HN post patterns for exactly this purpose.
