If you are feeling attacked, I get it. Most people are building or vibe coding in oversaturated or non-existent markets.

I was not about to have my 21st failed project, that was an L I could not accept. So I obsessively collected every signal I could since the new year

- abandoned repos - expired business domains - saas marketplaces - reddit and twitter sentiment - trademark records - removed apps - libraries gone quiet etc etc

The data is interesting but you still need to know how to use it. I threw together a newsletter since Mar and have climbed past 3k. Go figure it is the most successful thing I have build, giving away shovels for free.

I also am almost ready to release an MCP server so you can just tie it into your favorite frontier model and rubber duck with some more focused data points. You can vibe code an app, but not an idea.

Let me know if you want a sample from last month or to know if specific sources are being used that you are interested in.
