How to find SaaS buyers on Reddit using MentionLeads

By MentionLeads · July 15, 2026 · 3 min read

In short: To find SaaS buyers on Reddit, you need to monitor subreddits where founders and decision-makers ask for tool recommendations, using buyer-intent phrases like "looking for a tool that" or "recommend me a SaaS." MentionLeads automates this by scanning thousands of subreddits in real time for those phrases, then delivering the posts to your inbox. Set it up in under 5 minutes, and you'll have a steady stream of warm leads without manual scrolling.

If you want to find SaaS buyers on Reddit, you need to stop scrolling manually and start listening to the right signals. Reddit is a goldmine of buyer intent—people literally ask for tool recommendations every minute. The problem is noise. MentionLeads filters that noise by letting you monitor specific subreddits and keywords that indicate a person is actively shopping for a solution. Here's how to set it up and extract leads that actually convert.

What subreddits should you monitor for SaaS buyers?

Not all subreddits are equal. The best ones are where people ask for help with business problems that your SaaS solves. For B2B SaaS, focus on subreddits like r/Entrepreneur, r/SaaS, r/startups, r/smallbusiness, and niche communities like r/marketing or r/CRM. Also check r/ProductHunt and r/alphaandbetausers for early adopters. Use MentionLeads' /strategy tool to analyze your website and get a tailored list of subreddits based on your offer.

What buyer-intent keywords actually work?

Generic keywords like "software" are too broad. Instead, use phrases that signal active buying intent. Here are proven examples:

For example, if you sell project management software, monitor "looking for a project management tool" or "best alternative to Asana." MentionLeads lets you combine these with subreddit filters so you only see relevant posts.

How do you set up MentionLeads to find SaaS buyers?

Setting up MentionLeads takes less than 5 minutes. First, create an account and go to your dashboard. Click "Add Monitor" and enter your target subreddits (e.g., r/SaaS, r/startups). Then add your buyer-intent keywords as a comma-separated list. Choose whether you want to monitor posts, comments, or both. Enable email notifications so you get alerts instantly. MentionLeads will start scanning Reddit every few minutes and send you new matches.

How do you engage with leads without getting banned?

Reddit's community is sensitive to self-promotion. Never drop a link in your first reply. Instead, add genuine value first. For example, if someone asks "What's the best tool for email automation?" reply with: "I've used Mailchimp and ConvertKit. What's your use case? Happy to recommend based on that." After a few exchanges, you can mention your tool if it's a fit. Follow Reddit's content policy and subreddit rules. For more guidelines, see Reddit etiquette for businesses.
