Amanda Cassatt (née Gutterman) is an explorer of technology, economics, and culture. An early crypto entrepreneur, Amanda brought Ethereum to market as ConsenSys' Chief Marketing Officer from 2016 through 2019. During that time, Amanda also created Ethereal, the crypto cultural event series that hosted some of the first NFT galleries and popularized Ethereum from SXSW to Davos.

After working on Ethereum through its initial growth period, she founded Serotonin, the marketing firm and product studio for transformative technologies. Today Serotonin is the leading web3 strategy and marketing practice, with over 100 employees worldwide, supporting the top teams pushing the decentralization movement forward. With expertise spanning DeFi, DAO's, and NFTs, Serotonin supports premier web3-native projects like IPFS, Decentraland, Polygon, and Proof Collective, major brands entering web3 like Sotheby's, Aman Resorts, and Liverpool Football Club, and everything in between.

In addition to marketing and web3 transformation services, Serotonin has created an in-house product studio that builds and spins out software companies. The first such spinout is Mojito, the NFT e-commerce infrastructure platform used by Sotheby's, CAA, the Milwaukee Bucks, and more, that enables brands and creators to engage with web3. Serotonin's most recent product studio spinout is Franklin, the crypto-native payroll platform that makes payday everyday for web3 teams.

Amanda currently serves as CEO of Serotonin and President of Mojito. She was included on both the Forbes and Inc. 30 under 30 lists in 2016, and speaks at events from TechCrunch Disrupt to the WEF and SALT. Her work on Ethereum and NFTs has been covered in Vogue, The New York Times, The New Yorker, and Rolling Stone.
