Best subreddits for B2B startup founders
Where B2B founders share what actually gets enterprise deals across the line.
B2B founder communities on Reddit are where the real mechanics of enterprise selling get discussed — the procurement processes, the champion-building strategies, and the pricing conversations that B2B growth playbooks simplify into neat frameworks. Founders share what worked in specific ICP segments with enough detail to adapt to your situation.

How we know this+
This guidance reflects how our team actually works on Reddit. We research subreddits by hand, read each community's posting rules and moderator guidelines before recommending it, and spend time reading threads to understand the tone and what genuinely earns upvotes. Our recommendations favour community-first participation — useful posts and honest comments — over promotional shortcuts, and we revisit this page as communities change their rules and culture.

General posting guide for B2B Founders subreddits

The community can tell the difference between someone who has actually closed enterprise deals and someone who has read about doing it. Founder-led sales experiences — especially the unglamorous parts of early B2B selling — are the most valued content.
