How We Got Our First 100 Users From Reddit Mentions

When we launched Sift, we didn't have a marketing budget. No paid ads, no influencer deals, no Product Hunt launch with a coordinated upvote campaign. What we had was a product that solved a real problem and a Reddit account.

That turned out to be enough. Here's what actually worked to get our first 100 users, and what we'd do differently if we started again today.

Replying beats posting

This was the single biggest lesson. Our instinct at the start was to write posts - detailed breakdowns of what Sift does, why we built it, how it works. Some of those did fine. But the real traction came from replies.

When someone posts on Reddit asking how to find leads on social media, or how to monitor Reddit for brand mentions, or how to keep track of conversations relevant to their niche - that's someone actively looking for what you've built. A well-timed, genuinely helpful reply in that thread is worth more than ten self-promotional posts.

The maths is simple. A post is you broadcasting and hoping someone cares. A reply is you showing up exactly where someone already has the problem. The intent is completely different, and so is the conversion rate.

We still posted occasionally - maybe once or twice a month in relevant subreddits. But we quickly learned to be sparing with it. People get tired of seeing the same SaaS pop up in their feed, and if your name starts to feel like noise, you've lost more than you've gained.

Most of the time, don't drop a link

This one took some trial and error. Early on, we'd reply to a relevant thread with a paragraph of context and a link to Sift at the end. It worked sometimes, but it also triggered spam filters and made the comment feel like it existed solely to funnel traffic.

What worked better was mentioning Sift by name without linking to it. Something like "I built a tool called Sift that does exactly this — happy to answer questions if you want to know more." People who are interested will Google it or check your profile. People who aren't won't feel like they just read an ad.

Sometimes we went even lighter than that. "I actually built something for this — check my bio if you're curious" or "I made a tool that handles this, DM me if you want details." These feel like a person talking, not a brand marketing. The difference matters more than you'd think.

The times we did include a direct link were when someone was explicitly asking for tool recommendations and listing options. In that context, a link is expected and helpful. Context matters. Read the room.

Niche subreddits punch above their weight

We spent time in both large subreddits (r/SaaS, r/startups, r/Entrepreneur) and smaller, more focused ones. The niche subs consistently outperformed the big ones.

In a subreddit with 50,000 members who are all interested in social media marketing or community management, a relevant reply reaches exactly the right people. In a subreddit with 500,000 members where the topic is general entrepreneurship, your comment is competing with a thousand other things and the audience is far less targeted.

There's another factor too. Smaller communities tend to have higher quality discussion. People know each other, low-effort posts get called out, and genuine expertise is valued. When you show up and contribute something useful, people actually notice.

The bigger subreddits have their place, and we still participated in them. But if you're choosing where to spend your time, a handful of well-chosen niche communities will get you further than carpet-bombing every startup subreddit on the platform.

The AI slop problem is real

This needs to be said because it's gotten significantly worse recently. Subreddits like r/SaaS are flooded with AI-generated posts and comments. Entire threads that look like two bots having a conversation about productivity tools. Generic "Great question! Here are 5 tools that might help..." replies that clearly came from ChatGPT.

People see through it instantly. The phrasing is always slightly off. Too polished, too structured, too eager to be helpful in a way that no actual person talks. When your reply sits next to three AI-generated comments, the contrast is obvious. But only if your reply is actually written by a human.

We used AI as a tool — for brainstorming angles, tidying up phrasing, checking tone. But the actual content, the opinions, the specific experiences, the voice - that has to come from you. If you paste a prompt into ChatGPT and dump the output into a Reddit comment, you're contributing to the problem. And increasingly, communities are getting better at spotting and removing it.

The bar for "authentic" keeps rising because the floor keeps dropping. That's actually an advantage if you're willing to put in the effort. A genuine, human reply stands out more than ever precisely because so much of what surrounds it is slop.

What we'd do differently

Looking back, we wasted time early on trying to be everywhere at once. We'd have been better off picking five subreddits, becoming genuine regulars in those communities, and only expanding once we'd built real credibility in each one.

We also should have started replying sooner and posting later. We did it the other way around — led with posts because it felt more natural — and it took a few weeks to realise that replies were doing the heavy lifting.

The numbers

This wasn't overnight. It took roughly two months of consistent participation to reach 100 users from Reddit alone. Some days were quiet. Some replies got zero traction. A couple got hundreds of upvotes and drove a noticeable spike in sign-ups.

The compounding effect is what makes it work. Each genuine contribution builds your account's credibility. People start recognising your name. When you do mention your product, it carries weight because you've demonstrated you know what you're talking about in dozens of other threads where you had nothing to sell.

There's no hack here. It's just showing up, being useful, and occasionally mentioning that you built something relevant. That's it. But it works, and it's free, and it compounds in a way that paid acquisition never does.
