Today, early-stage investors and entrepreneurs find themselves in a dilemma in which they must choose between profit and impact; between traditional, for-profit-only models on the one hand, and multiple-bottom-line structures with a positive social or environmental impact on the other. At a time in which climate change, exponentially growing technologies, social polarization, and looming pandemics are calling into question humanitys priorities, this Report to the Club of Rome and the World Academy of Art and Science dissolves this dilemma by proposing a new investment paradigm, namely Integral Investing.Integral Investing incorporates and transcends the best practices of both traditional venture capital and impact investing. It provides a seamless integration and shows how technological progress need not be our rival, but can instead be our ally in ensuring the prosperous society we all want. Drawing on her own investments and stellar track record since 1995, the author reveals themechanism of Integral Investing. At the heart of it is a powerful, 360-degree de-risking tool called the Theta Model, which reveals how to make smart investment decisions based on the comprehensive integration of traditional due-diligence criteria, sustainability metrics, and assessments of the founders and team culture. But it doesnt stop there.In turn, this handbook demonstrates how to use human-centered AI to scale and digitalize the investment process. The goal here is to accelerate the use of exponential tech, capital, and consciousness leadership to transition to a sustainable global society: a process the author refers to as the Investment Turnaround. The 21 principles of Integral Investing, which she defines using Ken Wilbers Integral Theory, lead to her manifesto on how to implement the UN Sustainable Development Goals within Planetary Boundaries by 2050 through early-stage investing and entrepreneurship. Similar to the 15th century, when the Medicis inspiredthe Renaissance, today humanity is once again at a crucial turning point where pioneering public and private financiers, investors, entrepreneurs, and other committed individuals have the opportunity to leave behind the legacy of a prosperous society. This handbook provides a source of inspiration, and shows how self-actualization, a positive mindset, and a consciousness that is backed by a world-centric desire can become the driving force for solving the global grand challenges.
