Where it shows up
Every group here is a page of its own — each one checked daily.
The numbersIs it still shipping, is it overpriced, where did it land — and what the price is built from.
Hype can't move this line. Only verifiable outcomes do.
No money. No seat. It doesn't move the price. It goes on your record — and in 28 days reality settles it.
by reality anchor — the price money can't pump
AI. Launched 1d ago on Product Hunt, picking up 23 votes. Today, it's live, but nothing on the site has changed since we started watching. It's anchored at 681 pts.
It launched on Product Hunt with 23 votes.
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.
Quiet for 1 day — no penalty yet. Bleeding begins on day 7.
We fetch this site every day and hash what's on it. A founder can post “still working on it” — but if they actually shipped, the page changes. That's the only claim we price: evidence, not announcements. The real question isn't “will this be huge?” — it's “will they still be moving in four weeks?”
The story so farEVERY MOVE, AND WHY▾
Repriced every day, no cliffs. A launch that goes quiet bleeds a little at a time, so there's never a drop you could have run from the night before.
Momentum on its boardDOESN'T MOVE THE PRICE▾
Daily tracking just started for this launch — the first point is on the board. A second reading lands with tomorrow's run, and the curve builds from there.
How the launch is moving on its own board, day by day. This is the crowd's attention — it does not move the reality price. Only verifiable outcomes do.
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
Most grocery apps show you deals inside one store. CartHappy compares 350M prices a day across 10,000 stores, auto-applies every coupon, and splits your cart to whatever's cheapest that week. It can also learn your regular list and build your cart automatically — WXYZ Detroit tested it live on TV, saving a family $28 instantly. We built ours as an extension because it works horizontally, sitting inside each retailer's environment while helping the shopper shop across stores, not locked into one.

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.
