From Traditional Media to Web3 Innovation: Amanda Cassatt's Visionary Path

Amanda Cassatt emerged as a pivotal figure in Web3 branding and NFT commerce, building industry-leading platforms that transformed how businesses approach blockchain adoption. Her entrepreneurial ventures—Serotonin and Mojito—alongside her influential book “Web3 Marketing,” established her as a thought leader shaping the future of decentralized commerce and digital transformation.

Roots in Science and Storytelling

Growing up in Washington, D.C., Amanda Cassatt was surrounded by intellectual curiosity from an early age. Her mother’s work studying the brain and her father’s engineering background created an environment where analytical thinking and technological innovation were everyday conversations. This foundation naturally steered her toward careers at the intersection of technology and communications—fields where she would eventually leave a lasting mark.

After attending National Cathedral School, Amanda pursued higher education at Columbia University, graduating magna cum laude with a BA in English in 2013. Her strong academic foundation in language and narrative would prove instrumental in her later marketing and branding work.

Revolutionizing Creator Economics Through Slant

Amanda Cassatt’s early career took flight at HuffPost, where she joined directly under co-founder Arianna Huffington as a special projects editor upon graduation. She developed original editorial content and contributed pieces across various topics, gaining invaluable experience in digital media production and audience engagement.

However, her vision extended beyond traditional publishing. In March 2015, Amanda launched Slant—a platform with a radically different business model. Unlike conventional media outlets where companies captured the majority of advertising revenue, Slant returned the lion’s share directly to writers. This creator-first approach demonstrated Amanda Cassatt’s early understanding of platform economics and her commitment to empowering content creators.

Amanda Cassatt and the ConsenSys Chapter: Building Ethereum’s Brand

The blockchain revolution called, and Amanda answered boldly. In 2016, she joined ConsenSys as Chief Marketing Officer, taking on the responsibility of architecting the company’s global narrative during a critical growth phase. More importantly, she spearheaded the marketing strategy that helped position Ethereum as a foundational blockchain infrastructure.

During her tenure, Amanda assembled and led a marketing organization exceeding 50 professionals tasked with supporting ConsenSys’s portfolio of over 50 companies, including MetaMask (the dominant wallet interface) and Infura (the leading blockchain data provider). Her strategic work directly contributed to Ethereum’s evolution from an emerging technology into a robust ecosystem attracting institutional and retail participation alike.

Pioneering NFT Commerce with Serotonin and Mojito

After departing ConsenSys in 2019, Amanda Cassatt founded Serotonin—a marketing agency and product studio dedicated entirely to Web3. As CEO, she positioned the firm to guide emerging blockchain projects through go-to-market challenges and brand development.

Recognizing the commercial potential of non-fungible tokens, Amanda co-founded Mojito, an NFT trading platform designed for enterprises entering Web3. Mojito quickly became the preferred choice for major brands seeking to launch digital commerce initiatives on blockchain networks. The platform exemplified Amanda Cassatt’s ability to identify market gaps and build solutions that serve both businesses and Web3 communities.

Web3 Literacy and Industry Recognition

In 2023, Amanda published “Web3 Marketing: A Handbook for the Next Internet Revolution,” filling a critical gap in Web3 education. The book provides a non-technical yet comprehensive guide to Web3 concepts, making blockchain adoption and decentralized technologies accessible to business leaders unfamiliar with the space. Through both her publications and professional work, Amanda Cassatt continues advancing literacy around emerging technologies.

Her contributions garnered recognition from leading business publications. In 2016, Forbes and Inc. both featured Amanda Cassatt in their “30 Under 30” lists, acknowledging her impact on the intersection of technology, marketing, and innovation.

Legacy and Vision Forward

Beyond her professional achievements, Amanda Cassatt married Samuel Cassatt in 2019, maintaining focus on her mission to build a more decentralized and equitable digital future. Her evolution from journalist to Web3 innovator illustrates a fundamental principle: with vision, persistence, and intellectual courage, individuals can reshape entire industries.

Amanda Cassatt’s trajectory demonstrates that the future belongs to those willing to challenge conventional wisdom and build systems that empower users rather than extract value from them. Her continued influence in Web3 branding, NFT commerce, and blockchain education ensures her legacy will shape how the next generation of businesses and creators engage with decentralized technologies.
