How to Get Your First SaaS Customers on Reddit With $0 Ad Budget

Reddit gives early SaaS founders two ways in: answer people already describing the problem, or offer free access in communities that welcome feedback posts.

If you launched a SaaS with no ad budget and no audience, you already know how this goes. Cold-email tools cost money before they prove anything, and SEO takes months you may not have. Reddit gives you a different starting point: people are already writing the complaints, questions, and workarounds your product is supposed to help with.

Why is it so hard to land your first SaaS customers with no money and no audience?

Most founders ask for attention too early. They do not yet know how buyers talk about the problem.

1. They build in isolation and never validate with a real customer

Reddit post in r/SaaS titled "I built a SaaS for a year and got zero customers. Here's every mistake honestly." A red box highlights the founder's key admission: they spent a year building the product without talking to anyone who might use it — no validation whatsoever.

That is the first miss: no customer conversation, no search trail, no proof that the problem sounds the way the founder thinks it sounds.

2. They assume a good product gets found on its own

A good product still needs a path to the person who needs it. If you launch into silence, the product can be useful and still invisible.

3. They spray cold outreach at strangers

Cold outreach can work later, but it is a bad first move when you do not yet know the exact words buyers use for the problem. It is also not free: a basic cold-email stack of lead data, a sending tool, and a few warmed inboxes can run around $100 a month (Apollo's plans alone start there before you add inboxes). The spend buys no guarantee that you are talking to the right people.

These are different mistakes, but they create the same problem: the founder is still guessing. They are guessing what the buyer calls the pain, where that buyer looks for help, and what would make the buyer take a first step.

Reddit helps because some of that guessing is already resolved in public. You can see the exact complaint, the failed workaround, the words people use, and sometimes the urgency behind it. From there, the move depends on what kind of thread you found.

Reddit gives you two ways to get early customers

Use replies when someone already posted the pain and is asking for help. Use a feedback post when the community allows founders to share what they are building, and you need people to try the product before they can judge it. They are different motions, but the standard is the same: the post has to be useful to the community even if nobody buys.

Path 1: Reply to people already describing the problem

This is the cleanest move because the buyer's pain is already visible. You are not interrupting a stranger. You are answering a person who asked the internet for help.

Lead with a useful answer to the specific problem in the thread. If your product is relevant, say plainly that you're building something in that space, but leave the link out unless someone asks for it. Your profile can make the next step easy without turning the comment into a pitch.

Reddit comment from a founder advising others to directly engage in communities where their ideal customers hang out — the underlined line reads "a solid move is to directly engage in communities where your ICP hangs out" — saying that jumping into discussions and offering help is how they found their first users by building relationships first.

The difference is the order. A pitch asks for attention before it gives anything. A useful reply gives the reader something first, then leaves them a clean path to learn more.

So make the default move a public reply, not a DM. Answer the specific problem as someone who clearly knows it. Let people check your profile and find the product themselves. That is the reply format that consistently works on Reddit without tripping self-promotion rules.

Targeting matters too. Pick low-comment, high-intent threads where someone is actively asking right now — not 100-comment threads where your reply gets buried under everyone else's.

And treat a direct message as escalation, not the opening move. Reach out only after someone replies or engages, and only by referencing the exact problem they voiced. Cold-DMing strangers is what gets accounts flagged; the public reply is what earns you the right to message.

That is the part most founders get wrong. They treat Reddit like a colder version of email. The better move is slower: answer in public, make the answer useful without your product, and let interested people take the next step.

Path 2: Offer free access in communities that welcome feedback

Use this when the product needs hands-on use before the value is obvious, or when the problem is common but people are not asking for a tool in one neat thread. The goal is not to collect random free users. The goal is to find people who already have the problem, give them a low-friction way to try the product, and learn whether they would keep using it.

Some founder and builder communities are open to feedback posts. Many problem-specific communities are not. The permission comes from the rules and recent posts, not from the fact that your product is early or useful to you.

The r/buildinpublic sidebar showing rule 3, "No Self-Promotion Without Context," which asks members to share progress, lessons learned, and feedback requests instead of posting only for promotion.

Start here:

Keep the post short: who it is for, what problem it solves, what access you are offering, and what feedback you want. "Try my SaaS" is a promotion. This is better: "I built this for solo founders who spend hours finding Reddit posts from potential customers. If you have that problem, I'll give you free access. I'd like to know whether the leads are actually worth replying to."

Then stay in the comments. Ask what they have tried, what they would need before paying, and what made them skeptical. If someone sounds like a real fit, offer access and continue the conversation from the specific thing they said. Early customers often come from that back-and-forth, not from the post itself.

Do not spray the same post across every startup subreddit. Pick one or two communities, write for that context, and treat each serious reply like a customer interview.

How do you find the right threads and communities without scrolling Reddit all day?

Start manually until you can recognize both kinds of opportunity: pain threads worth replying to, and communities where an offer of free access would be welcome.

For replies, ignore broad discussion and crowded threads. Look for recent posts where someone describes a specific problem, explains what they tried, and is still looking for a better way.

For feedback posts, check the rules and recent posts. If similar posts get useful comments instead of mod removals or angry replies, the community may be a fit. If the rules say no self-promotion, skip it.

Once you know what a good opportunity looks like, dist0 can take over the search work. It learns your business from your website URL, suggests an initial set of subreddits to watch, and lets you replace or add communities based on what you already know. From there, it flags buyer-pain posts — people voicing the exact problem your product solves — and sends them as a daily market brief in Slack or email.

The trade is simple: instead of buying impressions with an ad budget you do not have, you find the conversations where the problem is already active. The manual version costs time. The assisted version saves the search time and leaves the human part with you: deciding whether to reply, offer access, or save the pain for content.

Once people engage, how do you keep track of follow-up?

You can do this with a spreadsheet. Track the Reddit user, thread URL, problem they described, what you replied, whether they answered, and the next follow-up. That sounds basic, but it matters. Reddit conversations are easy to lose after a few days, especially when you are replying in more than one community.

dist0 keeps that same lightweight lead list for you: each Reddit user, the posts and comments they wrote, the pains it detected in them, and their contact info — all exportable to CSV. It works for both paths: people who replied to your answer, and people who engaged with a feedback post.

Be clear about the boundary, though: it's not a CRM. dist0 finds and qualifies the lead; the relationship lives wherever you already work. You can export the CSV to your CRM, like HubSpot, when someone is worth following up with.

The loop is simple enough to run by hand: listen, reply or offer access, and keep a running list of the people worth following up with. The hard part is doing it consistently without turning Reddit into another inbox you avoid.

Turn repeated Reddit pain into content that keeps working

Content is the long-term play. It usually will not get a brand-new SaaS its first customers this week, but Reddit tells you what the content should be about.

Look for repeated pain. If the same complaint shows up in five threads, write the article that answers it better than a comment can. If people keep asking for alternatives to a tool, write the honest comparison. If people who tried the product keep misunderstanding the same thing, turn that into onboarding copy or a landing-page section.

This is where dist0 becomes more than a lead finder. It extracts buyer pains from Reddit posts, groups related pain into share-of-voice, and turns the repeated patterns into content ideas. When an idea is worth pursuing, dist0 can help draft the content brief: the angle, the section outline, and the Reddit context behind it. It does not replace your judgment; it gives you the raw human language keyword tools miss.

That is how the Reddit work compounds. The replies and feedback posts help you get early conversations. The repeated language from those conversations becomes content that can keep working after the thread goes quiet.

You started with $0 in ad budget and a Reddit tab. You end with early customers, a follow-up list, and a clearer read on what they were struggling with before they found you.

Frequently asked questions

  • Is it against Reddit's rules to promote my SaaS?

    Not if the community rules allow what you are doing and the post is useful without the pitch. For replies, lead with help and skip the link. For feedback posts, use communities that welcome feedback or builder updates, explain who the product is for, and ask for specific feedback instead of dropping a launch announcement everywhere.

  • Should I DM prospects on Reddit or reply in the thread?

    Reply in the thread first. A public, useful answer earns trust and a profile click. Treat a direct message as a follow-up only after someone replies, asks a question, or engages with your feedback post. Reference the exact problem they voiced.

  • How many customers can I realistically get from Reddit?

    Enough to get started, not enough to build a huge pipeline by itself. Replying and feedback posts both cost attention, so the channel is volume-bound. It is useful early because you get customers and language at the same time: the problems people repeat can become content, onboarding copy, or product positioning later.

  • Do I need a tool to do this?

    No. The method works by hand. The bottleneck is time: finding high-intent threads, choosing the right communities, and keeping track of follow-up means skimming a lot of Reddit. dist0 suggests an initial subreddit list from your website URL, lets you adjust it, sends buyer-pain posts as a daily market brief, and keeps a lightweight lead list so you start at the decision instead of the scroll.
