It’s a non-profit seeking to pool researchers in studying technologies in multidisciplinary fields. This is the mission from the Singularity University web site:
A number of exponentially growing technologies will massively increase human capability and fundamentally reshape our future. This warrants the creation of an academic institution whose students and faculty will study these technologies, with an emphasis on the interactions between different technologies. Our mission is to assemble, educate and inspire a new generation of leaders who strive to understand and utilize exponentially advancing technologies to address humanity’s grand challenges.
