Harry is the co-founder and President of Hollerith, a private Edtech company focused on creating software in the Edtech space. He has had a 40-year career building and leading successful businesses and investments in a range of capital-intensive industries including energy, power, shipping, rail and other sectors. Prior to forming Hollerith in 2019, Harry co-founded and managed two multi-billion-dollar investment and asset management businesses. 

From 2007 to 2019 Harry co-founded and was a Managing Partner of Alterna Capital Partners, a private equity firm investing in Core Capital Assets, the core operating assets of capital-intensive industries. To create Alterna he brought together several highly experienced origination and risk/portfolio management members of his prior CitiGroup team to continue the successful strategy developed and executed there. Over the next 13 years Harry led efforts to raise capital for Alterna's two principal funds, totaling approximately $1.2Bn of equity (deployed in over $2.5Bn of assets), primarily sourced from major US State pension funds and other institutional investors. He served as a member of Alterna's Investment Committee and performed various hand-on and lead roles in origination, management and realization for a range of portfolio companies and investments, including some of Alterna's most innovative, profitable and challenging investments. 

Prior to Alterna, Harry joined Citigroup in 1985, where he was elevated to Managing Director and would stay for the next 18 years. There he co-founded and led a highly profitable business investing in a diversified portfolio of assets within the capital-intensive industries noted above. That business grew to approximately $2.25Bn of equity invested in approximately $7Bn in assets with consistently strong profitability, outstanding risk performance and with numerous successful realizations. During that period, he became one of the few managing directors/business heads at CitiGroup who also held a Senior Risk Officer designation. 

Earlier in his career, Harry served as an officer in the United States Navy, co-developed and patented an innovative nuclear energy facility, and worked as an industry expert and asset manager for another major US financial institution (now part of JPMorgan Chase). Harry graduated from Purdue University with a BS degree in Interdisciplinary Engineering. He is a graduate of CitiGroup's Institute of Global Finance and Senior Risk Officer Programs.
