From Traditional Media to Web3 Pioneer: Amanda Cassatt's Journey in Blockchain Innovation

Amanda Cassatt emerged as a defining figure in Web3 branding and NFT commerce, establishing two influential companies—Serotonin and Mojito—after playing a pivotal role in Ethereum’s global expansion at ConsenSys. Her contributions span from pioneering decentralized marketing strategies to authoring “Web3 Marketing,” a comprehensive handbook that has guided organizations through blockchain adoption. Named in Forbes’ prestigious “30 Under 30” list in 2016, Amanda Cassatt has consistently pushed the boundaries of how technology and business intersect in the decentralized web era.

The Foundation: Early Career and the Writer’s Platform Revolution

Growing up in Washington, D.C., Amanda Cassatt was immersed in an environment where intellectual curiosity flourished—her mother’s background in neuroscience and her father’s software engineering expertise created a household that valued innovation and critical thinking. This foundation naturally led her toward technology and marketing during her university years.

After graduating with honors from Columbia University with a BA in English (2013), Amanda Cassatt launched her career at HuffPost as a special projects editor, working directly under founder Arianna Huffington. She developed original editorial initiatives and contributed extensively to the platform’s coverage. However, recognizing that traditional media models often concentrated wealth among publishers rather than creators, she founded Slant in March 2015—a publishing platform with a radically different approach. Slant pioneered a revenue-sharing model where writers captured the majority of advertising income generated by their content, fundamentally challenging the creator-economics model that had dominated digital publishing.

Catalyzing Ethereum’s Expansion: Amanda Cassatt’s Impact at ConsenSys

The trajectory shifted dramatically in 2016 when Amanda Cassatt joined ConsenSys as Chief Marketing Officer, overseeing the blockchain organization’s marketing function at a critical growth phase. Rather than simply promoting ConsenSys’s services, she architected Ethereum’s market narrative globally, transforming how the community understood and adopted the blockchain. Her leadership extended to building a marketing infrastructure of over 50 professionals who supported ConsenSys’s expanding portfolio—encompassing infrastructure leaders like Infura and wallet pioneer MetaMask, among 50+ additional portfolio companies.

This period represented a watershed moment for Ethereum. By coordinating messaging, managing ecosystem relationships, and establishing communication standards across portfolio companies, Amanda Cassatt helped legitimize Ethereum as a foundational blockchain infrastructure rather than mere speculation. Her work directly contributed to the ecosystem’s maturation into one of crypto’s most robust and developer-friendly platforms.

Establishing Web3 Infrastructure: Serotonin and Mojito

Following her departure from ConsenSys in 2019, Amanda Cassatt founded Serotonin in 2020, positioning it as a dual-purpose entity combining marketing agency capabilities with product incubation focused on Web3. As CEO, she directed the studio in launching category-defining blockchain initiatives while simultaneously identifying market opportunities in emerging Web3 use cases.

Recognizing the commercial potential in NFT commerce, Amanda Cassatt co-founded Mojito, an NFT trading platform designed specifically for enterprise clients seeking entry into digital commerce. Mojito rapidly established itself as the infrastructure of choice for established brands pursuing Web3 strategies, providing the technical and operational foundation for companies transitioning into decentralized markets. The platform’s focus on brand-native NFT experiences positioned it as distinct from consumer-facing NFT marketplaces, addressing a critical gap in enterprise Web3 adoption.

Thought Leadership: Amanda Cassatt’s Contributions to Web3 Literacy

Recognizing that the Web3 transition required not just infrastructure but education, Amanda Cassatt published “Web3 Marketing: A Handbook for the Next Internet Revolution” in 2023. The book translates complex blockchain concepts into actionable business frameworks for non-technical audiences—from marketing strategists to corporate executives. Rather than diving into cryptographic protocols, the handbook focuses on organizational adoption patterns, community building, and decentralized business models.

Through this publication and her continued consulting work, Amanda Cassatt has established herself as an authority on Web3 adoption strategy, helping organizations navigate the practical realities of blockchain technology rather than falling prey to hype or misconception.

Recognition and Ongoing Impact

Amanda Cassatt’s influence was formally recognized when she appeared on Forbes and Inc.'s “30 Under 30” list in 2016, an honor reflecting her early-stage accomplishments in technology and marketing. Beyond professional accolades, Amanda Cassatt married Samuel Cassatt in 2019, building both a personal and professional partnership.

Her evolution from digital media innovator to Web3 infrastructure builder demonstrates a consistent pattern: identifying structural inefficiencies and architecting solutions that empower creators and organizations alike. Whether through Slant’s creator-revenue model, her ecosystem-building at ConsenSys, or Mojito’s enterprise focus, Amanda Cassatt has repeatedly identified how decentralized systems could solve real business problems. Her trajectory exemplifies how vision, technical understanding, and business acumen converge to drive transformation in emerging technology sectors. As the Web3 space continues maturing, Amanda Cassatt’s foundational contributions and ongoing leadership serve as blueprints for how innovators can shape decentralized futures.
