The Google AI Impact Challenge (expired)
The Google AI Impact Challenge is looking for projects across a range of social impact domains and levels of technical expertise, from organizations that are experienced in AI to those with an idea for how they could be putting their data to better use. Since 2005, Google.org has invested in innovative organizations that are using technology to build a better world.
The Challenge is open to any nonprofit organization, public charity, or for-profit business from around the world, provided that they apply for a project that has a charitable purpose. Unfortunately, individuals without organizational affiliation are ineligible. Individuals and organizations that ordinarily reside or are located in Crimea, Cuba, Iran, North Korea, or Syria are not eligible to apply.
