About Greg Campbell

I advise and invest in people and projects that are disruptive, scalable and noble in their purpose. My background spans many industries, including food and beverage, healthcare, distribution, real estate, fintech and education. My fundamental belief is in the importance of the entrepreneurial spirit and the great things that are possible in business. I provide thought leadership to companies that have ideas that can become a mission, and in turn, be built into a scalable discipline and yield substantial value. I get excited about being around people that create new things, develop new markets and venture where others have previously not traveled. I bring to those I work with a disruptive mind frame. I find scalability critical for business success and a major criterion for the companies I partner with. I am proud to be associated with companies who enhance the lives of their customers and employees and protect the environment. Having a noble purpose reframes the discussion from solely money to how the business can truly make a difference.My experience in thought leadership enables me to produce content and create platforms to share impactful ideas across multiple mediums including podcasts, video, blogging, and public speaking.
