How to find product ideas on Reddit

Published 1 October 2026 · By Daily Product Idea · Our methodology

Why Reddit is worth searching

On Reddit, people describe their work in their own words: what went wrong this week, what they do about it, and what it costs them. That is exactly what a product idea needs underneath it. In the research behind Daily Product Idea, Reddit was the largest single source of problem signals. Of the 69 signals behind the 11 researched ideas published by 1 October 2026, 39 came from Reddit, and Reddit contributed to 7 of those 11 ideas.

It is also easy to use badly. Most posts are opinions, most complaints are one-offs, and the subreddits about building products are full of people describing other people's problems. The rest of this guide is about telling those apart.

Go where the customer talks, not where founders talk

The strongest signals come from communities of the people who have the problem, talking to each other about their work. A bookkeeper explaining a bad week to other bookkeepers is evidence. A founder guessing what bookkeepers need is a lead at best. Daily Product Idea's method rates a founder or builder community discussing someone else's market as medium-to-low relevance, because it is one step removed from the customer.

• LedgerLine, which turns supplier invoices into spreadsheet rows, drew 9 of its signals from r/Bookkeeping.
• UOM Bridge, which keeps stock counts and margins right for shops that buy in bulk and sell by weight, drew 7 from r/EtsySellers.
• Trade Reality Dossiers combined r/smallbusiness with trade communities: r/electricians, r/restaurantowners and r/PropertyManagement.

Start from a customer you can describe, then find their subreddit. Professional and trade communities are usually small and specific, which is what you want.

What a useful post contains

A complaint on its own is weak. Look for posts that show at least one of these:

• A workaround. What they do today instead. One r/Bookkeeping poster behind LedgerLine was typing more than 400 receipts a year into a Google spreadsheet by hand.
• A consequence. What it costs them, in time, money, errors or risk. Another described missing and inaccurate expense figures reaching the dashboard their boss reads.
• Repetition. Whether it happens every week or once a year.
• Spending. Money already going on the problem. A third poster was paying for an accounting plan and a paid add-on in the hope of importing their data, and found the add-on did not help.

Record each one separately. A post that only asserts "this wastes so much time" without saying how much is a weak signal, and should be scored as one.

Record what counts against the idea too

The same threads that show a problem often show its limits. One of the LedgerLine posters was explicitly looking for free or very cheap software. That is evidence about willingness to pay, and it points the wrong way. Keep it next to the supporting posts rather than leaving it out.

Then leave Reddit to check it

A problem that appears only in one community might be a quirk of that community. Check it somewhere else: reviews of existing tools, freelance job listings, issue trackers, search demand. Under Daily Product Idea's method, an idea is rated Supported only when at least two sites outside the original communities corroborate it. LedgerLine has 11 problem signals and is rated Indicative. More posts from the same place do not raise the level.

Be a good guest

Read a community for a while before asking anything, follow its rules on self-promotion, and ask about people's work rather than pitching your idea. Communities notice when they are being mined, and many remove posts that look like marketing. The people there are your future customers, and the most useful thing they can give you later is an honest conversation.

A short checklist

1. Choose a customer you can describe, and find the subreddits where they discuss their work.
2. Prefer professional and trade communities to founder communities.
3. Collect posts that show a workaround, a consequence, repetition or spending, and score bare complaints as weak.
4. Count each author once, and record posts that count against the idea.
5. Check the problem outside Reddit before treating it as more than a lead.
6. Ask about people's work; do not pitch to the community.
