    About Index & Thread

    We study what people trust. And what AI repeats.

    Index & Thread was founded by Jack Gierlich. Years spent studying Reddit taught us how people test claims in public. Today we map the claims AI assistants repeat about a category, trace where they formed, and help companies own the ones that decide the shortlist.

    FOUNDER

    Jack Gierlich

    I've been on Reddit for over 12 years. I've studied and participated in communities with very different rules and audiences. That's shaped how I think about showing up honestly on the platform.

    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.
