A weekly list of
problems worth solving.

University schedules change every week. New rooms, shifted times, professors swapping slots last minute. The founder says it was "a mess to keep track of," and manually adding each change to a calendar wasn't working.

$1k a month on a simple app, with no paid ads, shows students will pay to skip manual data entry. The app grew from a single YouTube mention to steady word of mouth. Running paid ads is hard to justify for a cheap, simple app, so finding new users is the open question for anyone building here.

The poster calls it the "yes man" problem: give an AI chatbot your business idea and it finds reasons to agree. This makes AI a poor tool for spotting real flaws before you spend time or money on something. Getting three models to debate each other correctly took the builder several months to get right.

The builder's willingness to spend months on this shows the problem is real, not just a brief complaint. AI models are trained to be agreeable, so they will keep doing this no matter which product you use. Founders who want honest criticism of their ideas have no good alternative today.

This Georgia landlord won an eviction case and holds a ~$10,000 court judgment for back rent and fees, but every collection agency they called refused the case, saying they only work before a judgment is issued. The landlord doesn't know how to get money taken from the tenant's wages by court order, or use other legal steps to collect. No clear service exists to fill this gap.

Hundreds of thousands of evictions happen in the US each year, and many end with a court judgment the landlord can't collect on. The legal steps needed to actually get paid after a judgment, like having a court order money taken from the tenant's wages or from their bank account, are steps most landlords don't know how to take. A service that handles this for a percentage of what's recovered has a simple, built-in payment model and a ready audience of landlords who already have court-ordered money they haven't been paid.

This seller filed copyright reports against shops copying her designs. Within days, a new shop appeared, used her exact photos, and filed false copyright claims against her originals. Etsy's automated system took her listings down. She documented extortion threats from accounts in Estonia and the Philippines, filed with the FBI, and emailed Etsy's legal team directly. She's still waiting for a human to respond while the attacks continue and more listings get copied.

Etsy has millions of sellers with original work and no clear path to get human review when the reporting system itself is being abused. A service combining listing-copy detection, pre-written dispute templates, and a direct contact at Etsy's legal team could charge $50–$150 per month to any seller earning real income from original designs. The seller in this post has 10,000 sales across two shops. She would pay today.

Most portable dual-monitor setups are plastic with dim panels and weak electronics. This product uses 2.5K glass bonded directly to the screen, runs both screens off a single USB-C cable, and has a custom circuit board that cost over $40k to develop. The full setup weighs 2.5kg, which the maker calls a fair trade for three screens on the road. Over 90 of the first 150 waitlist signups self-identified as software engineers.

The waitlist breakdown shows a specific, high-income audience that already spends heavily on hardware. A Kickstarter is set for July 27, 2026, with a numbered Founders Edition at below-retail pricing. No retail price is listed yet, but the $40k+ development cost and all-aluminum build point to a selling price above $500 with room for profit.

The seller has no Instagram page, no website, and no storefront, yet has completed over 175 orders. In one post with 53 comments sampled, five people asked about price and how to buy without being prompted. The product ships from India, accepts custom color combinations, and runs entirely through direct messages. There is no checkout, no product page, and no way for a buyer to find this independently.

A seller with real, paid orders and no proper place to sell has a lot of room to grow. The gifting market rewards products buyers can personalize, and this one already offers that. A simple storefront on Etsy or Instagram Shop could handle far more orders without the seller changing the product at all.

The poster spent weeks on a small Mitsubishi wall-mounted heat pump (MUZ-JP09WA) that loses power within seconds of the compressor starting. Three different Mitsubishi tech support agents gave three different diagnoses. The wrong inverter circuit board was replaced first, then the compressor under warranty. Neither fix worked, and the tech is back to the beginning of the service manual.

Wall-mounted heat pump units are in more buildings every year, but manufacturer phone support clearly has not kept up. A tech who has already spent weeks and hundreds of dollars on wrong parts would pay for a reliable remote diagnosis service staffed by people who actually know this equipment.

There is no affordable, automated way to paint detailed murals, signs, or art on large surfaces like walls, buildings, or playground floors. Businesses, schools, and property owners must hire skilled painters who charge by the hour for days of work. The post describes a robot that carries several paint colors, mixes them to match any shade, and moves back and forth across the surface to match the design.

Mural painting and large sign work is a real business category with steady demand from schools, companies, and property owners. The design side is already solved by digital tools. What is missing is a robot that can carry and apply paint on an outdoor or vertical surface accurately enough to match a design file.

A patient books a "routine cleaning" and arrives not knowing they might need more complex treatment. When the dentist explains the real diagnosis, the patient is already annoyed. That frustration often ends in a bad public review, even though, as the poster said, "clinically you did the right thing."

The fix is earlier communication, not better clinical work. A pre-visit intake form that flags likely complex treatment could prevent the frustrated review from being written. Dental practices already spend money on managing their online reviews, so there's a real budget for this.

Many continuing education lecturers won't share their slides with attendees. One dentist paid $1,000 three weeks ago, the course organizer asked for the slides several times, and the lecturer still refused. Without slides or a recording, attendees can't keep up with note-taking in a fast-moving lecture. The dentist who posted this says the frustration is making them skip future courses entirely.

Continuing education is required for a dental license, so this problem repeats every year for every practicing dentist. Lecturers guard their content because of real intellectual property concerns, which points to a controlled sharing tool: watermarked, view-only, with expiring access. The $1,000 ticket price shows this audience already spends heavily on CE.
