Dave Seminsky

Founder

After graduating from California Polytechnic in San Luis Obispo, Dave worked for a boutique Venture Capital firm in New York. In 2004 he accepted an offer from Apple Inc. to support the expansion of their retail stores.  When Apple expanded into Asia during 2009 he was asked to go.  At that time the concept of fresh roasted premium coffee did not exist in China.  For several years he struggled to find a decent cup of coffee.  A problem that became an opportunity. In 2012 he left Apple Inc. and started Sumerian Coffee in Shanghai.  Now his focus is on a larger problem, the financial challenges faced by coffee farmers.  His drive and determination is now aimed at identifying technological innovations as well as utilizing the by-products from coffee processing to make coffee farming a viable business.
