Google has never been a company to shy away from the big challenges in life, whether it’s creating self-driving cars, beaming the Internet from balloons, making human skin or abolishing death. Its latest example is a summit at the company’s Campus London space to try to figure out how world poverty could be eradicated within 15 years.

While it may sound a huge challenge, much progress has already been made. In 1990, the United Nations set a goal of halving global poverty levels by 2015, and the goal was actually reached five years early in 2010. Google now wants to complete the job – starting with an afternoon’s worth of ideas from tech entrepreneurs.

Google for Entrepreneurs is co-hosting a Tech Against Poverty summit on January 22 from 1pm to 6pm at Campus London, a Google shared office space specifically created for start-ups. Its partner in the event is Dreamstake, a support and investor platform for start-ups.

Google and Dreamstake want to test the hypothesis that the start-up culture will have a major positive impact on the poorest communities in the world. The event is open to Scientists, inventors, engineers, artists, thinkers and doers, and hopes to create some effective new thoughts in this space, with Google for Entrepreneurs actioning any ideas they see as innovating and taking a step closer to solving the problem.

The event is free, and you can register to participate at Dreamstake’s Solve for X website.
