She’s one of the key people who helped shape how the world understands Ethereum and the wider Web3 space. Amanda started out in media, climbed the ranks fast at The Huffington Post, and then pivoted hard into crypto when it was still the wild west.

She’s the kind of person who sees a gap between tech and people—and builds a bridge. Whether it’s through killer storytelling, bold marketing strategies, or launching her own Web3-focused agency, Serotonin, Amanda has been at the frontlines of some of the most important shifts in internet culture.

This is her story—from traditional media to blockchain leadership, and from editing newsrooms to building narratives for the decentralized internet. It’s a ride filled with vision, hustle, and a serious knack for turning complexity into clarity.

Early Life and Education

Curious from the Start

Amanda wasn’t born into crypto (none of us were). She was, however, the kind of kid who loved ideas, stories, and figuring out how things work. That natural curiosity became the core of who she is today.

Columbia University Days

She chose Columbia University, majoring in English—not exactly what you’d expect from a future crypto powerhouse. But that’s where she sharpened her thinking, dove deep into literature and philosophy, and started exploring big questions about communication, systems, and identity.

Books, Theory, and Big Ideas

If you’ve ever heard Amanda talk, you’ll notice she’s not just about tech—she’s about meaning. Her influences range from Derrida to digital media theory, and that shows up in how she talks about Web3 today.

Running the Show at HuffPost

Before crypto, Amanda was killing it at The Huffington Post as Managing Editor. She wasn’t just writing headlines—she was leading teams, designing content strategies, and understanding how the internet consumes media.

Learning the Digital Game

That time taught her a lot: how to grow audiences, make content pop, and manage complex digital ecosystems. All of that would become incredibly useful when she stepped into the Web3 world.

Jumping Into Crypto

Meeting Ethereum’s Inner Circle

Amanda’s shift to crypto wasn’t accidental. She was already exploring how new systems could shift power. That thinking aligned perfectly with the Ethereum vision. When she met Joseph Lubin (Ethereum co-founder and founder of ConsenSys), the stars aligned.

CMO at ConsenSys
