StackSignal
Know what's actually growing your Substack.
What it is
StackSignal is a growth dashboard for writers — built because the numbers a publishing platform shows you tell you almost nothing about what is actually working.
It pulls a writer's own performance alongside the competitors they care about, and turns it into something you can act on in a minute rather than stare at for an hour.
Who it's for
Substack writers and newsletter creators who are serious about growing, and who want to understand their free and paid subscribers rather than guess.
Most people use it on a phone or iPad, bouncing between the social apps and the dashboard, so that is what it is designed around.
What's inside
- Content — what you published, what it did, and which pieces are genuinely pulling their weight.
- Competitors — how writers in your space are performing, on normalised metrics so a smaller account can still win.
- Snapshot — the one screen that tells you where you stand right now.
How it fits the ecosystem
StackSignal is deliberately decoupled from the founder-facing brands — it stands on its own for writers who have never heard of the rest of A Roll Media.
It is the second piece of software heading for the Apple App Store and Google Play, behind Cardz Studio.
