Ohio Treasurer Josh Mandel launched the easy-to-use government transparency website in December 2014 by posting Ohio's transactions. Since then, Mandel has managed to get 650 local school districts and governments to add their data. The site, which has been searched more than 500,000 times, has data on $512 billion in government spending and 139 million transactions.
