Prosperity for the Planet
We invest in ambitious founders for one reason: innovation is the most powerful tool we have to build the future we want, and founders are the ones most likely to use it.Our planet’s resources – and the industries, infrastructure, and buildings built from them – have created extraordinary prosperity for humanity.
We cannot take that prosperity for granted. Instead, we must carry it forward. Give ambitious founders the opportunity to unleash innovation, challenge them to solve real problems, and watch them build meaningful technologies that strengthen prosperity while protecting our planet.
