We Speak Reddit.
Karmium was founded by marketers who were Reddit users first. We understand the platform from the inside out — and that changes everything.
Our Story
Karmium was born out of frustration. In 2019, our founder Alex Rivera watched brand after brand crash and burn on Reddit — not because their products were bad, but because they treated it like just another ad platform.
Reddit isn't Twitter. It isn't Facebook. It's 100,000+ distinct communities, each with its own culture, language, and unwritten rules. Getting it wrong doesn't just waste ad spend — it generates negative sentiment that spreads across the entire platform.
We built Karmium to bridge that gap: a team of genuine Reddit enthusiasts who also happen to be world-class marketers. Today we manage campaigns for brands across tech, gaming, crypto, consumer goods, and media — helping them earn their place on the front page.
What We Stand For
Authenticity First
We never fake it. Every campaign we run respects Reddit's culture and community norms.

Reddit evolves daily. Our team is embedded in the communities we manage, always ahead of trends.
