The fastest way to find your first SaaS customers on Reddit is to give Claude read access to Reddit, point it at the communities your customers already hang out in, and have it read every new post and comment there for you — flagging anyone who shows the problem you solve. That's the whole workflow: watch, judge, engage, and refine what “a good match” means as you learn from what works.
1. Which subreddits should I watch?
Start from the problem, not your product category — search for communities where people already talk about the pain you fix, not just ones named after your industry. A subreddit-search call finds candidates by name and topic; read a few days of each one's posts before committing, since the right community is often an adjacent one, not the obvious one.
2. How do I watch for new posts and comments?
Point Claude at those subreddits and have it check in — daily to start, hourly once you trust the workflow. It's a live read against Reddit each time, not a cache, so nothing you see is stale.
3. How does Claude judge whether someone's a customer?
Give it your product and the problem it solves in plain language, and ask it to read each post or comment against two questions: does this person actually have that problem, and are they showing any sign of wanting to fix it — asking what to use, complaining about a workaround, already paying for something worse. A prompt sketch:
“I'm building [product], which helps [customer] do [job]. Search r/[subreddit] for posts from the last day. For each one, tell me: does the author have this problem, are they showing buying intent, and quote the line that convinced you. Only flag the strong matches.”
Claude reads the whole post or comment thread, not just a title, so it catches people describing your exact problem in their own words — the leads a keyword search would miss entirely.
4. What do I do when Claude finds a match?
Engage as yourself, genuinely — answer their actual question or offer real help before anything resembling a pitch, and disclose who you are if you do mention your product. This is a conversation with a person, not a lead to close; the founders who do this well build a reputation in the community, not just a customer list.
5. How do I get better matches over time?
Tell Claude which flagged threads turned into real conversations and which were false positives, and ask it to fold that back into how it judges the next batch — tighter or looser on intent, different phrasing for the problem, subreddits worth dropping. Re-running the same workflow with a sharper prompt each week compounds fast.
Want to build this as a running, automated pipeline instead of a prompt you re-run by hand — with embeddings and ranking instead of Claude reading every item live? That's the deep dive: build your own semantic Reddit search. Setting Claude up with Reddit access in the first place: giving Claude access to Reddit. And if Claude isn't the only AI you want running this workflow: how to search Reddit with AI.

Frequently asked questions
Can Claude actually find customers for my SaaS on Reddit?
Yes, once it has real Reddit access — Claude can search the communities your customers use, read new posts and comments, and judge who has the problem you solve and who's showing buying intent, all from a plain-English instruction.
Do I need to build anything to try this?
No — connecting Claude to a Reddit API over MCP takes about five minutes, and the workflow itself is just prompts you run against it. Automating it into a continuously-running pipeline is a separate step, covered in the linked posts below.
Why can't I just ask Claude to browse Reddit for this?
Claude has no built-in Reddit access by default, so live browsing typically returns a refusal or stale results. Giving it a real API connection is what makes this workflow actually work — see why Claude can't search Reddit without one.
How is this different from the ThreadSnoop beta?
This workflow is something you run yourself, by hand, with your own prompts. The beta runs the equivalent pipeline continuously and automatically — semantic search, scoring, and a queue that learns your taste — so you review matches instead of re-running prompts.
We're building this as a done-for-you product
Join the beta and we'll run this workflow for you continuously — or build it yourself on the API if you'd rather own the pipeline.
The beta runs this automatically, continuously. The API is free to start — $0.50 credit, no card required.
