P.S. If you want more solo-founder distribution workflows like this one delivered to your inbox every week, join 3,000+ indie hackers getting them free.
Every solo founder knows the distribution struggle. You build something great, but getting people to see it feels like shouting into the void.
Reddit gets recommended constantly. "Just be helpful in subreddits," they say. "The traffic will come."
I spent two months testing this advice systematically. I tried five distinct engagement strategies across SaaS and indie hacker subreddits. Here's what worked, what flopped, and why most "Reddit marketing" advice is dangerously incomplete.
The Setup
I ran this experiment while promoting reddbot.ai — a tool I built that monitors Reddit for relevant conversations so founders can engage without refreshing /r/SaaS every 20 minutes. I wanted to see which strategies actually convert Reddit engagement into signups.
For fairness: I spent roughly the same time (about 30 min/day) on each approach, tracked every inbound click with UTM parameters, and gave each strategy a two-week window.
Strategy 1: The Helpful Commenter (Winner)
Answering questions thoroughly in /r/SaaS, /r/indiehackers, and /r/EntrepreneurRideAlong.
Result: 34% of total signups from the experiment.
This one works, but with a twist I wasn't expecting. Long, detailed responses (400+ words) got 5x more clicks than short helpful comments. The more genuinely useful information I packed in, the more people clicked my profile and found my tool naturally.
The key insight: I never linked my product in the comment. I linked it in my profile. People who were genuinely interested would visit my profile and discover it there. This kept comments pure and avoided the Reddit banhammer.
Strategy 2: Value-First Build in Public Posts (Winner)
Posting weekly progress updates, metrics breakdowns, and honest failures in /r/buildinpublic and /r/indiehackers.
Result: 41% of total signups.
This was the clear champion. A single post titled "I spent 4 months building a Reddit tool that nobody asked for — here's what happened next" drove more signups than any other single effort.
The pattern that worked: lead with a specific number (dollar amount, user count, time period), share a genuine failure or unexpected lesson, and end with a specific question to drive discussion. Posts without a question got 60% fewer comments.
Posts that got 50+ comments stayed visible on subreddit front pages for 12-18 hours instead of the usual 4-6 hours. The Reddit algorithm heavily rewards comment engagement.
Strategy 3: Crossposting Blog Content (Flop)
Taking my existing dev.to articles and posting condensed versions in relevant subreddits.
Result: 3% of signups. Complete dud.
Subreddits like /r/SaaS have gotten extremely hostile to what they perceive as content marketing. Even with a genuine "I wrote this, here's the TL;DR" framing, most posts got downvoted before reaching any real audience. Don't do this unless you want to trigger the community's spam detector.
Strategy 4: AMA (Mixed)
Running a "Ask me anything about building a SaaS as a solo developer" thread.
Result: 12% of signups.
The AMA got tons of engagement — over 100 questions in 24 hours — but most visitors were fellow builders looking for advice, not potential customers. The signup conversion was lower than I hoped. Great for building authority and backlinks, mediocre for direct acquisition.
Strategy 5: Cold DMs Based on Comments (Flop — and a Mistake)
Sending a direct message to people who posted questions my tool could solve.
Result: 0% signups. Several people reported me. Almost got banned.
Don't do this. It violates Reddit's content policy and community norms. Even if you're genuinely trying to help, unsolicited DMs about your product feel slimy. I learned this lesson the hard way.
What This Means for Solo Founders
The winning formula is simple: build in public + be genuinely helpful in comments, never link your product directly, and use a tool to monitor relevant conversations so you can respond fast.
That last part matters more than I expected. I found that responding within the first hour of a post being published got 10x the engagement of a response posted even 6 hours later. That's exactly why I built reddbot.ai in the first place — to automate the monitoring so I could focus on writing good responses instead of refreshing Reddit all day.
Two hours of intentional, high-quality community engagement per day outperformed 8 hours of scattered posting across platforms. Don't try to be everywhere. Pick Reddit, be ruthlessly helpful, and let your profile do the selling.
What about you? Have you tried Reddit as a customer acquisition channel? Which strategy worked for your product?
