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.
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.
Media. Launched 2d ago on PeerPush, where it placed #166. Today, it's live, but nothing on the site has changed since we started watching.
Quiet for 2 days — no penalty yet, but quiet doesn't stay free.
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 placed #166 on PeerPush with 6 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.
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
Video calls shouldn't start with "Can you hear me?" or "Give me a second, my camera isn't working." GreenSignal is a free desktop app that helps you check your setup before you join a meeting. With a single click, it verifies your camera, microphone, speakers, room noise, and network connection, then gives you a simple verdict: you're ready, almost set, or there's one thing to fix. Features: Camera check with live preview Microphone test with playback Background noise detection Speaker test Network latency and connection checks GreenSignal is designed for people who spend their day in Zoom, Microsoft Teams, Google Meet, Webex, and other video meetings. It focuses on quick reassurance rather than overwhelming diagnostics. Privacy is built in. Camera and microphone access are only used while running a check. Audio and video are processed locally on your computer and are never stored or sent anywhere. No accounts, analytics, tracking, or telemetry. GreenSignal is completely free and available for macOS and Windows.

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.
