Harrison Obiefule began his career working on global brands including Pepsi, Meta (Facebook), Google, Indomie, AB InBev, Rexona, JanSport, HP/Intel, and Kellogg’s, developing marketing and communications strategies for some of the world’s most recognised companies before transitioning to the blockchain industry in 2021.

Since then, he has led growth, marketing, and communications across Africa for international cryptocurrency companies including FTX and Bitget, both of which ranked among the world’s top five cryptocurrency exchanges by trading volume during his tenure. At FTX Africa, he helped grow monthly trading volume in Nigeria from $5 million to $500 million within a year and in South Africa from $50 million to over $2 billion. He also launched the Ghana market, growing monthly volume from virtually zero to more than $100 million at its peak, alongside supporting growth across other African markets.

Harrison served as Nigeria Lead for Superteam, helping grow Solana’s ecosystem through community building, developer education, partnerships, and startup support. During his tenure, Solana was recognised as Nigeria’s most active blockchain ecosystem for two consecutive years, while Nigeria accounted for 66% of Africa’s Solana developers and ranked sixth globally for Solana developer participation. He supported market expansion for products like Jupiter, Solflare, Raenest, Roqqu, and GetEquity, and led a partnership with the Federal Ministry of Youth Development to launch NiYA’s first blockchain course. In 2025, Superteam Nigeria reached $1 million in community GDP and collaborated with SEC-licensed exchanges Quidax and Busha. His work supporting founders also contributed to commercial outcomes, including the October 2026 acquihire of Superteam-incubated startup Evolution by Nuvion.

Harrison now serves as Senior Global Marketing Strategist at Nuvion, a global banking platform, where he drives marketing strategy across international markets, spanning product launches, acquisition, activation, and retention.

Harrison is a sought-after speaker at high-level blockchain forums. He was invited to present at the University of Cambridge’s Digital Assets Innovation Industry Regulation and Compliance Executive Program and was among a small group of industry thought leaders invited to address Nigeria’s House of Representatives Ad-hoc Committee on the Economic, Regulatory, and Security Implications of Cryptocurrency Adoption.

Harrison holds a Doctor of Business Administration with a specialisation in Marketing and Media Management from Rome Business School and is currently pursuing a PhD in Marketing.
