Rhiannon Payne | CEO

Based in San Francisco, CA, Rhiannon specializes blockchain consulting, whitepaper creation, and marketing. She launched Sea Foam Media in 2017 after spending three months in Dublin, Ireland with friends and colleagues in the AI and machine learning industry. She identified a need for companies like these to better manage their massive amount of data curation and annotation work, and hired a team to do just that.

Due to her interest in cryptocurrency, she introduced a new segment of the company focused on working with ICOs (Initial Coin Offerings) and DApp (Decentralized Application) projects, which quickly became Sea Foam Media’s core focus.

From 2016-2017 Rhiannon also worked on the ground in Tokyo, Japan, leading the product development of a SaaS application for the concierge teams at The Ritz-Carlton and Grand Hyatt, Tokyo. She managed an international team of designers and developers to build the app, which was successfully launched in Spring of 2017, during the Sakura full bloom. She also played a critical role in selling the product to other 5 star hotels across Japan.

Rhiannon’s experience also includes 5+ years as a marketing manager and project manager in the FinTech space, leading teams that generated upwards of one million dollars each month in revenue. During this time she cultivated many lasting relationships, which ultimately brought her to the cryptocurrency and blockchain space as an investor and consultant.

Chloe Diamond | Marketing Associate

Based in London, UK, Chloe works as a Marketing Associate at Sea Foam Media. She became interested in cryptocurrency after her time living in Tbilisi, Georgia in 2015 where she began noticing a trend towards Bitcoin and Ethereum mining in rural parts of the country. She was previously working in a graphic design and marketing position but was eager to be more involved in something that could make a difference and solve real-world problems.

During this time, she started reading about emerging technologies which she found directly applied to her lifestyle and values, as the decentralised nature of crypto brings many opportunities to people and places that are often overlooked.

Her other interests include art and heritage, AI technology, and sustainable living. She values anything that works on a global scale, that is all-encompassing for people around the world and prioritises using technology to create the most sustainable environment possible.
