Forty years ago, Bill and his childhood friend Paul Allen bet that software and personal computers would change the way people around the world worked and played. This bet wasn't exactly a wager. It was an opportunity to make computers personal and empower people through the magic of software. Some people thought they were nuts. But the bet turned out well.

Fifteen years ago, the two of us made a similar bet. We started our foundation in 2000 with the idea that by backing innovative work in health and education, we could help dramatically reduce inequity. The progress we've seen so far is very exciting — so exciting that we are doubling down on the bet we made 15 years ago, and picking ambitious goals for what's possible 15 years from now.

OUR BIG BET
The lives of people in poor countries will improve faster in the next 15 years than at any other time in history. And their lives will improve more than anyone else's.
