Everyone tells you to "post on Product Hunt" or "announce on LinkedIn."
And then you do it. You get 47 upvotes, 12 supportive comments from other founders, zero signups, and a mild existential crisis.
Here's the thing nobody tells you early enough: beta users don't find you. You find them. And the best ones aren't waiting in some launch platform inbox. They're on Twitter and Reddit, right now, actively complaining about the exact problem your tool solves.
I learned this the hard way. This is what actually worked.
Why Twitter and Reddit Are the Best Places to Find Beta Users
Most distribution advice for SaaS is built around audiences you don't have yet. "Build an email list." "Grow your following." "Post consistently."
All good advice, eventually. But when you're pre-revenue and need 10 real users who'll give you honest feedback? You need intent, not reach.
Twitter and Reddit are the only two platforms where people publicly express buying intent in real time, for free, with no ad spend required.
On Twitter, people tweet frustration at tools they're already paying for. On Reddit, people ask "is there anything better than X?" in niche subreddits every single day.
Those aren't leads. Those are gifts.
Twitter: Three Signals That Actually Mean Something
1. Competitor Followers With Bio Filters
Start with your biggest competitor. Pull up their follower list and start filtering by bio.
You're looking for keywords that match your ICP, things like "founder," "sales," "growth," "SaaS," "indie hacker," "B2B." Anyone who follows a competitor AND has a relevant bio is a warm lead by definition. They've already opted into this category of tool.
This is slow, manual work. Do it anyway. At the beta stage, manual is the right answer.
(Side note: this is literally one of the core things I built Nodott to automate, filtering high intent leads on X by bio keywords, competitor signals, and buying behavior. But even if you're doing it manually, the logic is the same.)
2. Competitor Mentions: The Complaint Thread Gold Mine
Go to Twitter search. Type:
"[CompetitorName]" sucks"[CompetitorName]" frustrated"[CompetitorName]" doesn't work"[CompetitorName]" anyone know alternative
What you find there is the rawest possible form of buying intent. These people are already paying for a solution. They're unhappy. They want out.
That's your in.
Don't pitch them. Give them value first. Reply with a genuinely useful insight, a workaround, a resource, something that helps even if they never sign up for your product. Build the relationship in public. The DM comes later, after trust is established.
3. Competitor Comments: The Highest Intent Signal of All
Here's the one most people completely miss.
When someone comments on a competitor's tweet, asking a question, expressing confusion, sharing a use case, that person is actively engaged with the problem your tool solves. They're not passively following. They're participating.
These are your highest intent beta prospects on the entire platform.
Your job is simple: reply to that comment with genuine value. Answer their question better than the competitor did. Share a perspective they haven't considered. Make yourself useful in that thread.
You're not hunting for users. You're becoming the most helpful person in the room. The signups follow naturally.
Reddit: Find the "Is There a Better X?" Posts
Reddit works differently but the intent signal is even more explicit.
Search your niche subreddits for:
"alternative to [competitor]""looking for a tool that does X""anyone else frustrated with [tool]""[competitor] vs anything else"
Posts like these are people in active buying mode. They've already identified a problem, tried a solution, and found it lacking. They are one good recommendation away from becoming your user.
Don't spam links. Reddit will bury you and the community will hate you for it.
Instead, write a genuinely helpful comment. Address what they actually need. If your tool is a natural fit, mention it briefly at the end, but only after you've earned credibility in that comment. Something like: "I actually built something that handles exactly this. Happy to share more if it'd be useful."
Soft. Helpful. Honest.
That framing converts better than any feature list.
The Repeatable System
Once you've found your hunting grounds, make this a daily habit, not a one time sprint.
A simple non negotiable:
- 10 minutes on Twitter every morning: check competitor mentions, reply to 3 to 5 comments with actual value
- 10 minutes on Reddit every morning: search your niche subreddits for intent posts, leave one genuinely helpful comment
- 3 DMs per day to the highest intent people you engaged with earlier in the week
That's it. That's the system.
It doesn't feel like a growth hack. It feels like showing up and being useful. Which, honestly, is exactly what it is.
I built Nodott to handle the signal finding part of this automatically. It monitors Twitter and Reddit every few minutes for high intent buyers based on competitor mentions, bio filters, and complaint patterns, so you can spend your time on the conversations, not the searching. If that sounds useful, it's worth a look. But even without it, the manual version of this system works. I know because I did it first.
One Last Thing
The biggest mistake I see early founders make is treating beta user acquisition like a broadcast problem: post once, announce loudly, wait for replies.
It's not a broadcast problem. It's a conversation problem.
Your beta users are already out there, already vocal, already looking for something better. You just have to show up in the right places, say something useful, and let the relationship do the work.
Twitter and Reddit are noisy. But they're also honest in a way most platforms aren't. The frustration is real. The intent is real. And the opportunity, if you're patient enough to be genuinely helpful instead of immediately pitching, is very real.
Go find your people. They're already talking.
