Seller Intelligence
Not what buyers
want to buy.
What sellers
should sell.
We mine Reddit for real buyer pain points to find which product categories are underserved — and worth entering.
Dish Drying Rack
Every material fails — metal rusts, plastic cracks — and buyers are actively hunting for a durable alternative they can't find.
Top pain points
All Reports
Dish Drying Rack
Every material fails — metal rusts, plastic cracks — and buyers are actively hunting for a durable alternative they can't find.
MagSafe Wallet
Nearly every brand fails on magnet strength and card capacity — a seller who nails both has a clear path to $30–60 price point.
Miniature Model Tree
Woodland Scenics dominates but is overpriced — a seller offering comparable quality at lower cost with stable bases and accurate scale labeling wins immediately.
Over-the-Sink Cutting Board
Small kitchens are a massive, vocal pain point on Reddit — and an over-sink cutting board is the cheapest way to add prep space without a renovation.
Wood Car Air Freshener
Mainstream chemical-scented fresheners are actively hated — a natural wood alternative with replaceable inserts addresses every top complaint and commands a premium.
Silicone Cooking Utensil Set
Silicone was supposed to solve the plastic problem — but buyers are discovering it creates new ones, and no set on the market addresses all of them at once.
How this works
Reddit mining
We search product-relevant communities for real complaints, comparisons, and unmet needs — not reviews.
Pain point analysis
Posts filtered for signal: "I wish it had...", "switched from X because...", "does anyone make a version that..."
Seller verdict
Findings translate into direct market entry guidance: what to build, what to avoid, what price point makes sense.
Frequently Asked Questions
What is WhatToSell?
WhatToSell is a product research tool for e-commerce sellers. We mine Reddit to find real buyer complaints and unmet needs, then translate those findings into actionable market entry guidance — opportunity scores, pain point breakdowns, and seller verdicts.
How is this different from product reviews?
Review sites write for buyers. We write for sellers. We don't tell you which product is best to buy — we tell you which product categories have unsatisfied demand, what buyers are complaining about, and whether there's a viable opportunity for a seller to enter.
How do you research products?
We search Reddit communities like r/BuyItForLife, r/Frugal, and category-specific subs for posts where buyers describe real frustrations: things they wish existed, products they've abandoned, and complaints that repeat across multiple threads. We scan dozens of posts per product and filter for high-signal evidence.
What does the Opportunity Score mean?
The Opportunity Score (1–10) reflects how strong the market gap is for a given product. It considers complaint frequency, how many buyers are actively searching for a better solution, and how feasible it is to actually build one. A score of 8+ means real, persistent demand with no satisfying product on the market.
Who is this for?
Amazon FBA sellers, Shopify store owners, product designers, and anyone sourcing goods who wants to know what buyers actually want — not what the market already has. It's research for people who sell, not people who shop.
Is this free?
Yes, all reports are free to read. We publish new product analyses regularly as we expand our research pipeline.
