Challenge.gov is an online challenge platform administered by the U.S. General Services Administration (GSA) in partnership with ChallengePost that empowers the U.S. Government and the public to bring the best ideas and top talent to bear on our nation’s most pressing challenges. A challenge is exactly what the name suggests: it is a challenge by one party (a “seeker”) to a third party or parties (a “solver”) to identify a solution to a particular problem or reward contestants for accomplishing a particular goal. Prizes (monetary or non–monetary) often accompany challenges and contests.Challenges can range from fairly simple (idea suggestions, creation of logos, videos, digital games and mobile applications) to proofs of concept, designs, or finished products that solve the grand challenges of the 21st century.On Challenge.gov, the government and the public work together to find submissions. Government agencies post challenges on this site and the public can post submissions to these challenges.Once a challenge is created, other people can join the challenge to propose a submission, discuss the challenge, and show support. Incentives, which are payable only if a challenge is solved, encourage others to solve a problem and earn their rewards.
