PainBase turns public complaints from Reddit, Hacker News and more into scored startup opportunities, then a landing page to test them
PainBase
Validate before you build, with real complaints and real revenue data
The classic founder story goes: code in secret for six months, launch, hear crickets. PainBase is built to flip the order. Before you write a line of code, it shows you what people in your space are already complaining about, pulling public posts from Reddit, Hacker News, Dev.to, Lobsters and Indie Hackers through official APIs, scoring the pain with AI, and linking you to the original threads so you can read the exact words your future customers use.
Each problem gets a Gap Score from 0 to 10, which multiplies how urgent the complaint is by how scarce existing solutions are. AI research reports dig deeper on a niche, and a competitor analysis pulls out rivals' strengths, weaknesses, pricing models and the gaps where a new product could stand out.
Where it shines
The markets board is the standout. PainBase groups thousands of startups with revenue verified through TrustMRR into sub-markets, then ranks them by size, growth and how much of the revenue the biggest player holds. When the leader holds a small share, nobody has consolidated the market yet, which is exactly the kind of opening a small team can win. You can walk from market to startups to pain points to a scored idea in one flow, or start from your own idea in the validator.
Then comes the bit marketers will love: pick a validated pain point and PainBase generates HTML landing page code with copy aimed squarely at that problem, ready to host anywhere and point traffic at.
The best way to start
Run a free scan on your idea and browse the markets board without signing up. If the signals look promising, choose a monthly plan or the one-time Founder Pass for monthly report credits, alerts and the full feed. Set up Telegram alerts for your niche, read the raw threads to borrow your buyers' language, then ship the generated landing page and send it its first visitors. The PainBase blog has practical guides on doing exactly that.
Starts where smart launches start: with what people are already begging someone to fix.
