Jack Gierlich
I've been on Reddit for over 12 years. I've studied and participated in communities with 2.1 million members combined—experience that shaped how I think about authentic platform presence.
I've watched thousands of brand interactions succeed and fail, and seen what the system rewards. That experience is what we bring to clients.

Why This Matters
Most agencies guess at Reddit. We don't have to.
Other agencies read Reddit's marketing guides and hope for the best. We've spent years inside the system watching what actually works.
We know what the system removes
We've watched thousands of posts disappear. We know exactly what triggers community and algorithmic action.
We know how communities decide
Years inside the system means we understand how norms form and what members actually look for.
We know what gets upvoted
We've seen millions of posts. We know what content earns attention in different communities.
We speak Reddit
We've been here for over a decade. We don't sound like marketers because we're not.
