Our take

Founded in 2020, Serotonin is a marketing firm and product studio for transformative technologies. It helps companies develop and get attention for their Web 3.0 applications.

Serotonin was always well positioned within the industry given the pedigree of its founding team. For example, founder Amanda Cassatt is a pioneer in Web 3.0 and even assisted in the launch of the Ethereum blockchain.

The company birthed a new startup in Mojito, which has raised capital and is now supporting Sotheby’s Metaverse by helping sell NFTs. This lateral growth forebodes a promising future for the parent company as it looks to innovate in a market that has huge potential.

Company values

1. Tenacity - There is always a way. We won't quit until we've found it. We cultivate a culture of tenacity, where challenges and problems are shared as much as solutions and successes. We celebrate drive, determination, positivity and persistence. We get the job done
2. Transparency - Clarity, confidence, and trust are at the heart of effective partnerships. There is no 'need to know basis', we lay it all on the line. With partners, clients, and teams we share information and reasoning. We debate and discuss openly and honestly. We strengthen our relationships by being transparent, and as a result, produce better, more meaningful work
3. Teamwork - It's right at the core of the work we deliver: the way we work together. As an agency team, and with our clients. We are all heading for the same goal, and that means pulling in the same direction, leaning into individual strengths, and achieving the win together
