This guide breaks down the best subreddits for startups across different categories, with specific strategies for each community.

Tier 1: The Essential Startup Subreddits

These are the communities every startup founder should know about. They have the largest audiences and are most receptive to startup content.

r/Entrepreneur (4.8M subscribers)

The largest entrepreneurship community on Reddit. It's a mix of aspiring entrepreneurs, side-hustlers, and experienced founders sharing advice.

• Best for: Sharing your journey, lessons learned, and milestone posts
• Posting rules: Requires 10 comment karma in the subreddit before posting. No direct promotion, but value-based content that mentions your product is generally allowed.
• Strategy: Start by commenting on other posts for a week. Share genuine insights from your startup journey. Frame promotional posts as "here's what I learned" rather than "check out my product."

r/startups (1.9M subscribers)

More focused on tech startups and venture-backed companies. The community is knowledgeable and critical.

• Best for: Getting feedback from other founders, discussing startup strategy
• Posting rules: Very strict moderation. Most promotional content is removed. They have monthly "Share Your Startup" threads where promotion is allowed.
• Strategy: Save your promotional posts for the monthly threads. Otherwise, focus on asking thoughtful questions and sharing non-promotional insights.

r/SideProject (444K subscribers)

One of the most startup-friendly subreddits. Explicitly designed for people building projects.

• Best for: Launching new products, getting early feedback, finding beta users
• Posting rules: Self-promotion is allowed if you're seeking feedback. Use appropriate flairs.
• Strategy: Frame your posts as seeking feedback, not as product announcements. Show your work-in-progress. The community loves seeing the building process.

r/IndieHackers (98K subscribers)

The Reddit home for bootstrapped founders. Smaller but highly engaged community.

• Best for: Bootstrapped products, revenue milestones, behind-the-scenes content
• Posting rules: One self-promotional post allowed per user using the "SHOW IH" flair. Must be for feedback, not marketing.
• Strategy: Share your revenue numbers, growth strategies, and lessons. This community values transparency. Use your one promotional post wisely.
