Reddit vs Hacker News for B2B lead gen: which wins?
By MentionLeads · July 20, 2026 · 5 min read
In short: If you need warm leads from buyers actively searching for solutions, Reddit wins. If you need credibility with technical founders and early adopters, Hacker News wins. Most B2B startups should start on Reddit for volume and use HN for positioning — but the playbooks are completely different, and mixing them up wastes time.
Reddit vs Hacker News for B2B lead gen isn't a fair fight — they serve different audiences and reward different behaviors. Reddit gives you access to millions of users asking specific questions about tools, pain points, and workflows. Hacker News gives you a small, high-signal audience of technical decision-makers who upvote thoughtful commentary. The platform you pick should depend on your ICP, budget, and patience for community norms.
What does the Reddit audience look like for B2B?
Reddit's B2B audience is broad and intent-rich. Subreddits like r/smallbusiness, r/entrepreneur, r/SaaS, r/marketing, and r/sales are filled with people asking "What tool do you use for X?" or "How do I solve Y problem?" — these are organic buying signals. The platform skews toward SMB owners, solo founders, and mid-market operators. If you sell to technical founders or bootstrapped startups, Reddit is a goldmine. If you sell to enterprise procurement teams, Reddit is mostly noise. The key is finding subreddits where the conversation is about solving a problem, not just venting.
What does the Hacker News audience look like for B2B?
Hacker News (HN) is a community of YC-alumni, engineers, and early-stage investors. The audience is smaller (roughly 5-10 million monthly visitors vs Reddit's 500M+) but hyper-concentrated in tech. HN users are cynical, anti-marketing, and quick to flag anything that smells like promotion. However, a single upvoted comment or "Show HN" post can land you meetings with CTOs, VCs, and other founders. HN works best for developer tools, infrastructure, and deep-tech B2B products. It's terrible for services, consulting, or anything that requires a sales pitch.
How do engagement and conversion potential compare?
- Reddit: Warm leads from comment replies and DMs. Conversion rate on a well-placed comment can be 5-10% for a free consultation or demo. Volume is high — you can engage 20-30 threads per day. - Hacker News: Cold outreach via HN is nearly impossible. Most leads come from someone seeing your "Show HN" or comment and reaching out to you. Conversion is higher (if they come to you) but volume is low — a few leads per month at best. - Tradeoff: Reddit gives you control over outreach; HN gives you passive credibility. If you need leads next week, use Reddit. If you're playing a long game, use HN.
Which platform should a B2B startup prioritize?
Start with Reddit if your product has a clear, urgent pain point that people post about (e.g., "How do I automate invoicing?" for a billing tool). Use this free tool to find subreddits where your ICP hangs out. Focus on subreddits where the rules allow helpful comments — never link to your product in the first reply. For B2B SaaS, this guide on high-intent subreddits lists specific communities that consistently convert. Use HN only if you have a genuinely novel product and can write a compelling "Show HN" post — expect tough questions and no mercy.
What are the biggest mistakes founders make on each platform?
On Reddit: posting links immediately, ignoring subreddit rules, and using generic sales copy. The #1 mistake is treating Reddit like a billboard. On HN: posting a "Show HN" for a me-too product, writing a blog post instead of launching, and getting defensive in comments. HN users smell desperation. The right approach on Reddit is to answer questions genuinely for 2-3 weeks before mentioning your product. On HN, the right approach is to launch early, be transparent, and engage every single comment.
How do Reddit and HN compare to LinkedIn for B2B?
LinkedIn is better for reach and direct messaging, but the intent is lower — people are in "professional networking" mode, not buying mode. Reddit has higher intent because users are actively asking for solutions. HN has the highest technical credibility but the smallest reach. If you're selling to SMBs, Reddit > LinkedIn. If you're selling to enterprise, LinkedIn > Reddit. For a full breakdown, see our comparison of Reddit vs LinkedIn for B2B lead gen.
Frequently asked questions
Can I automate Reddit lead generation without getting banned?
Yes, but only if you use tools that respect rate limits and avoid posting spam. Manual engagement is safest. If you automate, focus on monitoring keywords and sending notifications — never auto-post or auto-DM. Reddit's anti-spam systems are aggressive; a single automated comment can get your account shadowbanned. For a safe automation approach, see our guide on avoiding Reddit shadowbans.
Is Hacker News good for B2B lead generation at all?
Yes, but only for specific products: developer tools, open-source projects, and deep-tech B2B. If your buyer is a technical founder or engineer evaluating infrastructure, HN can generate high-quality inbound leads. But you cannot actively prospect there — you have to earn attention organically. Expect 1-5 qualified leads per launch, not 50.
How do I measure success on each platform?
On Reddit: track replies to your comments, DM conversations started, and demo calls booked. Use UTM parameters on any links you share. On HN: track upvotes on your Show HN, comments (especially follow-ups from users who say they'll try it), and direct emails from HN users. Don't measure vanity metrics like karma — measure conversations that lead to a sales call.
