A weekly list of
problems worth solving.

Each week we read Reddit and pick the complaints that look like real business ideas worth building.

Editor's note

A note before the list.

Two of this week's five ideas point at the same thing: people are tired of paying monthly for software they'd rather own once. "Pay-Once Mac Apps Still Sell" scored 5 out of 5 on demand, and the proof is already in the numbers: 100 paying customers in 30 days, no paid ads, from a developer who has released 11 apps this way. That's the one I'd start with, because pay-once works and buyers are already looking. If you build any of these, I'd love to hear how it goes.

Until next Thursday,

Screen Recorder, No Subscription, Ten Sales

Buyers emailed back within 48 hours, without being asked, with the same line: they wanted to own a screen recorder, not pay for it monthly. Ten sales, zero ads, two days.

The problem

Screen Studio charges monthly and free alternatives look ten years old. A solo dev in India spent $5k of their own money to build Screenbolt, a $39 one-time Mac app that auto-zooms on every click during export, cleans up voice, and delivers a finished video with no editing needed. Ten buyers replied to their receipt emails without being asked with nearly the same line: "I was tired of paying Screen Studio every month and just wanted to own the damn thing."

Why it's interesting

Pay-once pricing for tools people use a few times a month has real demand on Mac, and no good option currently exists. Ten buyers proved that by paying $39 each within the first 48 hours, with zero advertising.

Pay-Once Mac Apps Still Sell

A solo dev charged $39 once for a Mac screen recorder and got 100 paying customers in 30 days, spending nothing on ads. He has released 11 apps this way.

The problem

The poster says buyers are "tired of $20-30/month subscriptions for tools they open twice a week." He charged $39 once, with lifetime updates included. He raised the price in steps ($39 for the first 100 buyers, $49 for the next 100, $79 after), and replied personally to every email in the first 72 hours. That got him 100+ paid users and about $900 in month one.

Why it's interesting

About 35% of his revenue came from customers who had already bought one of his other apps. Those customers came back for each new release. Twitter brought clicks and comments but almost no traceable sales. Any subscription-heavy tool category is now a target for a pay-once Mac alternative.

Indie Tool Makers Can't Find Buyers

Someone built a video tool that cuts 4-5 hours of work down to 15 minutes, priced it at $79, and got 84 comments and zero sales. They tried every piece of standard launch advice. None of it produced a sale.

The problem

The poster launched a $79 movie recap video tool on Indie Hackers. It ran locally, saved 4-5 hours per video, and got 84 comments on launch day. No sales. They posted in communities, made a demo, and followed the usual advice. There is still no clear place to sell niche one-time tools that are not subscription software.

Why it's interesting

Indie makers building non-subscription tools have no obvious place to sell. Platforms like ProductHunt and Gumroad get comments and clicks, but not buyers. A marketplace where buyers go, not just curious visitors, would solve a real problem in how indie makers sell their tools.

Small-Batch Casting Service for Indie Toy Makers

Making figures at home takes too long, and factory runs cost too much for small orders. There is nothing in between for indie toy creators.

The problem

Ron has released 4 figures. Home resin printing was "brutal and slow" because of the number of parts in each figure. Factory runs fixed the speed problem but were "very expensive" for small batches. He is now trying to learn casting himself rather than pay someone who already knows how to do it.

Why it's interesting

Designer toy brands sell in limited releases, often 50 to 200 units at a time. At that scale, factories don't work. Their smallest orders are far larger than that. A small-batch silicone casting service built for indie figure makers could charge per run or per unit, with no obvious competitor targeting this niche today.

Battery-Built-In Outdoor TV for Tailgaters

Campers and tailgaters want a weatherproof TV with a battery inside. After a long search, this poster can't find one with decent reviews.

The problem

The poster hauls a generator or separate power station plus a TV to every outing. That's too much gear. They want one unit: battery built in, weather-resistant, tough enough that they don't have to treat it gently. After searching for a while, they called it their "white whale" and said nothing they've found has good reviews.

Why it's interesting

The RV and tailgating crowd spends real money on outdoor gear and replaces cheap items that break. If the current products on the market all have poor reviews, there's a real opening for a brand that gets the hardware right and builds a reputation in this community.

How these ideas are picked.

Every Thursday a small program reads a list of subreddits where people post about problems they would pay to fix, or show products that strangers are asking to buy. Posts that look like real ideas get sent to a language model. The model rates each one 0 to 5 on three things: how clear the problem is, how strong the demand looks, and how big the market could be.

None of these ideas have been checked. Treat them as places to start your own research, not as final answers. The best signal here is often the comment thread on the original Reddit post, not the scores.
