The numbersIs it still shipping, is it overpriced, where did it land — and what the price is built from.
League price & chart
No money. No seat. It goes on your record — and in 28 days reality settles it.
Calls are closed while we rebuild accounts. You can still read every one of them.
Productivity. Launched 16d ago on Product Hunt, picking up 10 votes. Today, the site itself changed 9d ago — evidence it's still shipping, not just announcing.
Moving right now. The clock only starts when a launch goes quiet.
We check this site every day, ourselves. A founder can post “still working on it” — a claim like that doesn't price. What we price is what we can verify from the outside: evidence, not announcements. The real question isn't “will this be huge?” — it's “will they still be moving in four weeks?”
The market viewHow this launch is priced and ranked in our league — the investor side of the page.
ranked by the reality anchor, not the market price
It launched on Product Hunt with 10 votes. It also showed up on 3 other boards — but didn't place well enough on any of them, so none of them add to the price. Listing on twelve directories is free; placing well on them isn't.
No matter how much money goes in. There is no pump here — you can't make yourself right by buying more. The line only moves on things that actually happened: an award, revenue that grew, a new platform, code that shipped — or silence.
6 quiet days in between are left out — nothing happened on them. A launch that goes quiet eases down a little at a time — never a cliff you could have run from the night before.
How the launch is moving on its own board, day by day — the crowd's attention.
A flat line is normal: votes stop within a day or two of launch, on every board. What's unusual — and what actually counts — is a launch that keeps pulling votes long after its day is over.
About
PDF Dark turns any PDF into a real dark-mode file you can download, share, and reread anywhere. The entire conversion happens in your browser — your file never touches a server. A saturation-based algorithm preserves photos and charts in their original colors while darkening the rest. Output is a standard PDF (not a viewer toggle). Free, MIT-licensed, no signup, no ads.

The board it did best on sets the price. Every other board only adds to it if the launch also placed high on that board too — because just showing up somewhere isn't an achievement. Listing on twelve directories is free; placing well on them isn't.
