Sean Ryan – 2019 20 Under 40 Honoree


Sean Ryan

Co-Founder, Chief Technology Officer, NODE40
Albany, NY

Prior to his entrance into the blockchain industry, Sean was a noted academic – with degrees in Computer Science as well as Information Science. He served as a lecturer whilst working in a myriad of engineering roles for the New York State government. Following 9/11, he was involved as a researcher in a DARPA-funded Naval Intelligence program, developing software for identifying terrorism-related patterns in written mediums.

After leaving the public sector, Sean turned his efforts to the realm of private consulting, working with clients in everything from healthcare to information management. Sean’s passion for cryptocurrencies and blockchain tech led him to co-found NODE40 in 2015, a sophisticated platform for investors, traders and CPAs that ensures compliance with the somewhat vague regulatory guidance on cryptocurrency taxation.

Sean frequently writes for accounting and legal publications, and is often sought for his opinion by cryptocurrency news platforms.
