Reddit vs Hacker News for Launching Your Startup
Reddit has 1.36 billion monthly active users and drives 3-5x more raw traffic. Hacker News front-page posts reach 50-100 angel investors, but only 2.3% of submissions ever get there. This playbook covers both platforms with step-by-step launch tactics, mini case studies, and a clear decision framework so you pick the right channel, or use both.
The Short Verdict: Use HN for Investors, Reddit for Users
Hacker News is built for engineers, founders, and investors. A successful Show HN post can put your product in front of 50-100 angel investors and 10-20 VCs in a single morning. But the bar is steep: only 2.3% of all HN submissions made the front page in Q1 2026, and the median Show HN post scores just 2 points. You need 30-50 upvotes in the first hour to break through.
Reddit, with 1.36 billion monthly active users (up 19% year-over-year as of Q4 2025), drives 3-5x the raw traffic volume of a typical HN launch. Communities like r/SaaS, r/startups, and r/indiehackers are packed with real users who buy SaaS tools, not just browse them. Both platforms are free. Most startups should use both, but on different timelines and with a different post for each.
Platform Comparison Matrix
Every key dimension side-by-side so you can make a data-driven decision in minutes.
Who Actually Sees Your Launch Post?
Understanding the audience on each platform changes everything about how you write, what you include, and what outcome you optimize for.
The HN audience is one of the most technically sophisticated audiences on the internet. The average reader has shipped production code, run a company, or sits on a cap table. They are not browsing casually.
Reddit's startup audience is broader, more diverse, and more willing to try new products. They respond to personal stories, genuine struggles, and real lessons learned. They buy tools and share recommendations widely.
How to Launch on Hacker News: 6 Steps
Show HN posts appear in a dedicated /shownew queue with a grace period where downvotes are disabled, giving your submission a fair window. But that window closes fast. Here is the exact sequence that maximizes your odds.
Build karma by commenting for 2+ weeks first
HN heavily weights account age and karma. A post from a day-old account with zero comments will be penalized algorithmically even if it gets upvotes. Spend two weeks commenting on threads in your domain. Add genuine technical insights. Aim for at least 50-100 karma before your launch day.
Choose Monday, Tuesday, or Wednesday morning, 9am ET
HN front page velocity matters most in the first 30-60 minutes. HN traffic peaks Monday through Wednesday between 8am and 12pm Eastern. Posting Friday afternoon is the single most common mistake founders make. You will miss the bulk of the active HN audience.
Use the exact title formula
The title formula is non-negotiable: "Show HN: [Product Name] - [one-sentence technical description]". No marketing adjectives. No exclamation marks. No "revolutionary" or "amazing". HN moderators routinely flag posts that violate this. Example: "Show HN: Replimate - Self-hosted analytics for Next.js with zero-config setup".
Write a detailed first comment explaining your journey
Immediately after posting, add a comment as the top-level reply on your own post. Cover why you built it, what problem it solves, who the target user is, and what you are looking for (feedback, beta testers, or paying customers). This comment gets more reads than the linked page itself for many Show HN posts.
Respond to every comment within 30 minutes
HN ranks posts partly by engagement velocity. Every reply you write extends the active lifecycle of your thread. Set aside 2-3 hours on launch day to do nothing but respond. Thank critics. Answer technical questions directly and completely. Never be defensive.
Do not post other content on the same day
Posting multiple things to HN on the same day dilutes your credibility and can trigger spam filters. On Show HN day, go silent on all other HN activity. Stay focused on your launch thread. Also avoid sharing the link on social media and asking friends to upvote, as HN detects coordinated upvote rings and penalizes them.
How to Launch on Reddit: 6 Steps
Reddit rewards authenticity over polish. A story-driven post from a real founder who struggled, iterated, and built something useful will outperform a perfectly crafted product announcement every time. Platforms like MediaFast can help you craft launch posts that match each subreddit's tone without sounding like a robot or a press release.
Identify 3-5 target subreddits before launch day
The right subreddit selection is more important than the post itself. Start with r/SaaS, r/startups, r/indiehackers, and r/entrepreneur. Then find one niche subreddit specific to your product category: if you built a tool for developers, add r/webdev or r/programming. Check each subreddit's rules carefully, especially self-promotion policies.
Build 30 days of karma in your target subreddits first
Reddit's spam filters and moderators both penalize accounts with no history in the subreddit. For 30 days before your launch, comment genuinely in the subreddits you plan to post in. Help people with questions. Share feedback on others' products. This karma acts as a social proof signal for both the algorithm and the community.
Write a story-driven post, not a product announcement
The highest-performing launch posts on Reddit follow a specific narrative arc: "I had this problem. I tried existing solutions and they failed me. So I spent X months building my own. Here's what I learned along the way. And here's the link if you want to try it." Titles like "I spent 6 months building X, here's what I learned" consistently outperform "Introducing X: the best Y for Z".
Post Tuesday through Thursday, 8-10am ET
Reddit traffic peaks midweek during morning hours in North America. Tuesday through Thursday between 8am and 10am ET is the optimal window for startup subreddits. Avoid Monday (people are catching up from the weekend), Friday (attention drops sharply after noon), and weekends (low traffic in B2B-adjacent communities).
Respond to every comment within the first 2 hours
Reddit's algorithm uses engagement rate heavily. A post with 30 comments from an active OP will outrank a post with 60 comments where the author went silent. Thank every person who gives feedback, even if it is critical. Critical comments give you the chance to show that you are a responsive builder who takes users seriously.
Cross-post to one additional subreddit 48 hours later
After your first post gains traction, cross-post to one other relevant subreddit 48 hours later. Do not cross-post immediately, as it looks spammy. Tailor the title slightly to fit the second community's tone. For example, a post for r/SaaS might emphasize the business metric angle, while the same product on r/indiehackers might emphasize the solo founder journey.

Illustrative Launch Outcomes
These scenarios are illustrative examples based on typical patterns seen across both platforms. They are not attributable to specific named companies.
Analytics Tool, Show HN Launch
A bootstrapped analytics tool launched on Show HN with a plain-English technical description, hit the front page within 2 hours, and received 15 qualified beta requests from engineers at Series B companies.
HN delivers quality over quantity. The 15 requests were from exactly the right personas.
Productivity SaaS, r/SaaS Launch
A productivity SaaS posted a "I built this in 3 weekends" story on r/SaaS, reached 800 upvotes, and drove 1,200 signups in 48 hours from the subreddit alone.
The "I built this in weekends" framing resonated because Reddit users root for the underdog builder.
Developer Tool, Dual Launch
A developer launched on both platforms the same week. HN brought 8 investor conversations. Reddit brought 3x the signups. The combination gave them enough traction for a pre-seed round.
Investors want to see social proof. Reddit signups gave the HN conversations more weight.
Decision Framework: Choose the Right Platform for Your Goal
Use this framework to decide where to launch first. Most startups will eventually want both, but your current stage and goal should drive the sequencing.

Timing and Frequency: When to Post, When to Wait
Both platforms have well-documented optimal windows. Ignoring timing is one of the most common reasons a good product launch underperforms.

Account Requirements Before You Launch
Both platforms have invisible account quality filters that will silently tank your launch if you ignore them. Most failed launches are not about content quality. They are about account history.

Community Rules: What Gets You Removed
Breaking the rules on either platform results in silent removal. Most of the time you will not even be notified. Understanding what moderators and algorithms penalize is as important as knowing what they reward.
How to Handle Comments on Each Platform
The comment section is not a formality. On both HN and Reddit, how you respond to comments determines whether your post climbs or dies. These are different skills for different audiences.

Reddit vs Hacker News: Common Questions Answered
6 questions founders ask before choosing between Reddit and HN for their startup launch.
It depends on your goal. Reddit drives 3-5x more raw traffic and is better for user acquisition across a broad startup community. Hacker News front-page posts reach 50-100 angel investors and 10-20 VCs, making it superior for fundraising and developer credibility. Most early-stage founders benefit from doing both, but on different timelines and with different goals.
Show HN is a dedicated section on Hacker News (news.ycombinator.com/shownew) where founders and builders share products they have made. Show HN posts appear in a separate /shownew queue with a grace period during which downvotes are disabled, giving your submission a fair chance. A successful Show HN post must follow the title formula: "Show HN: [Product Name] - [one-sentence technical description]". No marketing language is allowed.
Very hard. Only 2.3% of all submissions reached the front page in Q1 2026. The median Show HN post scores just 2 points. To reach the front page you typically need 30-50 upvotes within the first 30-60 minutes of posting. Hitting 50 points puts you in the top 6% of all HN submissions.
The most launch-friendly subreddits are r/SaaS, r/startups, r/indiehackers, and r/entrepreneur. For developer tools, consider r/webdev or r/programming. For consumer apps, look for niche subreddits where your exact target audience spends time. Avoid overly broad subreddits like r/technology for launches, as they have strict self-promotion rules.
Yes, and it is often the best strategy. The key is to not post on both platforms on the same day. Launch on Hacker News first on a weekday morning (Monday through Wednesday, 9am ET) and give it 48-72 hours. Then launch on Reddit with a story-driven post on Tuesday through Thursday, 8-10am ET. This way you maximize attention on both platforms without splitting your energy.
The exact formula is: "Show HN: [Product Name] - [one-sentence technical description]". For example: "Show HN: Supbase - Open source Firebase alternative". Avoid adjectives like "revolutionary", "amazing", or "best". HN users reward clarity and specificity. Keep it under 80 characters. No exclamation marks, no marketing language.
