Leadership Team

Phil Harvey

Phil Harvey - CEO

Phil’s career began in the UK Special Forces, aged 19 (the youngest in history). He retired from the military and entered the blockchain space in 2014. His expertise in operational planning and execution skills, is underpinned by his experience in elite military operational planning. Phil has developed end-to-end cryptocurrency operational procedures and policies based on his intricate working knowledge of cryptocurrency mining facilities. He has devised innovative new approaches and techniques in mining, often in response to technical challenges or driven by the constant aim of improving efficiencies. He is able to deliver turnkey crypto mining operations with relative ease. 

Phil took an unheard-of new entity to a significant player within the crypto mining space within North America. In only a few years he grew the company from start-up to over 70,000 servers and over 200Mw, making it one of the larger cryptocurrency miners at that time. With this began Phil’s passion to design, build and operate mining farms.   Thus SABRE56 was born.
