TL;DR

• A subreddit is a community forum where users can participate by asking questions and sharing experiences.
• A Reddit account is a prerequisite for creating a subreddit that will be based on your industry or product.
• Once the subreddit is created, ensure you post content that will spark discussions and engage with your audience in a timely manner.

If you’re a B2B SaaS startup, chances are you’ve already realized how favorable Reddit can be - real users, honest feedback, and niche communities for just about every industry. But trying to talk about your product in someone else’s subreddit might feel like walking on eggshells. Most communities have strict rules, and even well-intentioned posts can get flagged or removed.

That’s why creating your own subreddit can make all the difference. It gives you a space to speak openly, share updates, host discussions, and connect directly with your users, without having to tiptoe around someone else’s rules. More importantly, it gives your users a place to talk to you- to ask questions, report bugs, share ideas, or vent frustrations - knowing someone from the team is actually listening. And when people feel heard, they’re much more likely to stick around and become part of what you’re building.

In this article, you will learn what a subreddit is, how to create one for your startup, and how to grow it into a space where your users feel involved, valued, and invested in the product.

What Is a Subreddit?

A subreddit is a focused community or forum within Reddit, dedicated to a specific topic or industry. Each subreddit is identified by r/[name] (e.g., r/SaaS, r/marketing, r/devops) and has its own URL, such as reddit.com/r/YourSubredditName.

Reddit users join subreddits related to their industry or interests. Additionally, every subreddit is run by moderators (often the creator or a small team), who enforce rules, manage posts, and shape the tone of the community. Some subreddits are casual and meme-friendly, while others are highly focused and strict about what you are posting.

How To Create a Subreddit?

Let’s say you have developed a B2B SaaS platform named FlowRaft that helps product and operations teams design, automate, and optimize cross-functional workflows, without needing to write code. Now, you are planning to build your presence on Reddit by creating an official subreddit for your community. Here are the step-by-step instructions on how to create subreddit.

1. Create a Reddit Account

The foremost step is to create a Reddit account to begin with the official subreddit for your company. You will need to come up with a unique username or the platform will create it by default.

2. Navigate to the Menu and Click on ‘Create a community’

Once you have created your Reddit account, head to the menu bar on the left and click on ‘Create a community,’ under the ‘Communities’ section.

3. Fill In the Required Details About Your Community

Fill in the Community Name and Description that defines your product. Make sure that you mention that it is an official subreddit. This will help the Reddit users to understand that whatever they communicate on the subreddit will be gathered as feedback and that the new features or bug fixes will be informed.

4. Make It Visually Appealing

The next step involves adding the icon and banner, wherein you will be adding your company’s logo in the icon and a banner image that matches your theme.

5. Select the Topics Related to Your Subreddit

Select the topics that are related to your platform, such as Software and Apps, that align with the niche of your product. So, whenever a Reddit user searches this topic, your subreddit will also be listed.

6. Choose the Privacy Settings & Click on ‘Create Community’

Then, choose your desired privacy option out of Public, Restricted, and Private.

• If Public, the Reddit users will be able to view your subreddit, publish a post, and even comment.
• In the case of a Restricted subreddit, the users can view it but cannot engage with posts and comments.
• If you don’t want the users to even view your subreddit, you can keep it Private.

However, since you are creating this subreddit to build a community, it should be Public.

Once you have created the Subreddit, you can choose moderators who will have the ability to flag unwanted posts or comments and maintain the decorum. You can also set rules for your subreddit, so the users don’t do anything that violates the guidelines.

How To Grow a Subreddit?

Growing a subreddit for Reddit marketing requires consistent effort and a focus on providing value to your members. Here are the tips to grow your subreddit and gain more members:

1. Write a Welcome Post

Start by creating a warm, informative welcome post to introduce new visitors to your community. Explain what your subreddit is about, who it’s for, and any guidelines or expectations. For instance,

“Welcome to r/FlowRaft – the official community for FlowRaft users and workflow enthusiasts! This is a place to ask questions, share tips, and get the latest updates on no-code workflow automation.”

Consider sticking this welcome thread to the top of your subreddit so every newcomer sees it. You might even make it a recurring monthly thread, inviting new members to introduce themselves or ask questions.

2. Seed Your Subreddit With Content

Before you invite others in or promote your subreddit, publish some quality posts in it. In fact, Reddit recommends at least 3 posts so that visitors find something interesting when they visit your subreddit. As the moderator or founder, start posting content that will spark discussions and share resources related to your product. Here are a couple of content ideas to get started:

Ask Me Anything (AMA) Posts

AMAs are a popular Reddit tradition where an individual (often a founder, executive, or expert) answers community questions in real-time. For example, the CEO or lead developer of FlowRaft could do an AMA about no-code automation or the story behind the product.

This gives your community direct access to ask questions and learn more. AMAs help you engage with your users and build credibility. In fact, they give you an opportunity to answer questions about your product with context and showcase thought leadership in your industry. Be sure to announce the AMA in advance to get a good turnout, and genuinely engage with the questions asked.

Informative Posts Related to Your Product

Share educational content that provides value to your target users. Post things that establish your expertise and help users solve problems. For FlowRaft’s subreddit, this could include how-to guides (e.g., “Step-by-Step Guide to Automating an Onboarding Workflow with FlowRaft”), case studies or success stories from clients, industry insights on process automation, or tips and tricks for productivity.

The key is to focus on useful, relevant insights rather than just promoting your product, so that readers are more likely to engage and trust your content. By posting such high-quality content early on, you set the tone for the community and give people a reason to join and stay active on your subreddit.

5. Engage With Your Community Consistently

Active engagement is crucial for subreddit growth. Reply to comments, answer questions, and appreciate people for sharing their thoughts. For example, if a FlowRaft user posts a question about a feature or a suggestion for improvement, respond promptly and helpfully.

This not only provides support to that user but also shows how much you care for your customers. This consistent active engagement can turn one-time visitors into regular contributors.

6. Cross-Post From Relevant Subreddits

Cross-posting is one of the best ways to gain visibility by sharing helpful content from other subreddits (from your domain) into yours. This is something you can do when you run out of content. This keeps your community active and full of useful discussions, even if you haven’t built up original content yet.

For example, if someone shares a great post about workflow automation in r/NoCode, you can cross-post it into your r/FlowRaft subreddit with a caption like,

“This insight aligns closely with how teams use FlowRaft, curious what others think?”

This does two things:

• Keeps your subreddit fresh with high-quality and relevant content
• Starts conversations without needing to create every post from scratch

Just make sure the content truly fits your niche, and always give proper credit.

Conclusion

Creating a subreddit is a simple process, but it’s important to be clear about what you want to achieve. Whether it’s building your own Reddit community, gathering feedback, or educating users about your product or latest features, having a purpose will guide everything you do.

Before inviting people in, make sure your subreddit feels alive. Post a few discussion-worthy questions, share product insights, or start a conversation around common pain points your users face. A well-seeded subreddit creates a better first impression and encourages early engagement.

If you’re unsure how to make a Reddit community thrive or how to attract the right audience, consider seeking Reddit marketing services. Agencies like Infrasity specialize in helping startups grow meaningful and well-moderated communities on Reddit.
