Recover logo

Recover

Government-funded online addiction treatment

Recover provides more effective and affordable addiction treatment via telemedicine. We partner with local governments to save lives and taxpayer dollars. More than 20 million Americans struggle with addiction, but less than 10% of people who need it receive treatment. For those that do, it usually does not work - only 8% get better. Most of this treatment is funded by governments, and goes to programs that are frequently predatory, and focus more on profit than people. We have created an effective, accessible, and affordable solution: Recover. We offer a proven approach using medication and counseling, that can improve outcomes for over 70% of patients. It reduces overdoses by 80%, death by 50%, and has years of research and application showing it works. Despite how effective this medication can be, most rehabs do not have medical professionals on staff. Not only does our program work better and bring medicine to addiction care, it also costs just 10% of traditional programs. Nick founded Recover after seeing his family and friends struggle with addiction. He was raised by a drug addict, has an alcoholic brother, and lost an uncle to heroin. He saw how hard it is for people to get the treatment they need, and how ineffective existing options are. We are working to make sure that people like Nick’s family have access to best-in-class addiction treatment so they can get and stay well.

Recurious

thesixtyone is Digg for new music, a social filter for the tsunami of indie creativity hitting the web. Like Digg, the homepage is community driven. Listeners who sign up are given a daily number of "hearts" they can use to vote on songs they like. If songs you heart become popular, you earn reputation points, level up, and unlock community abilities. Listeners can also earn achievement badges for various activities, like hearting songs in under-explored genres or reaching a playcount milestone. All tracks are fully streamable and can be organized in tag-based playlists. To lubricate the experience, they've invented an ajax navigation system that allows listeners to enjoy seamless audio playback across pageviews.
