ResearchGate is a social networking site for scientists and researchers to share papers, ask and answer questions, and find collaborators. The site has been described as a mash-up of “Facebook, Twitter and LinkedIn” that includes “profile pages, comments, groups, job listings, and ‘like’ and ‘follow’ buttons”. Members are encouraged to share raw data and failed experiment results as well as successes, in order to avoid repeating their peers’ scientific research mistakes.
ResearchGate members receive automatic alerts for new publications authored by their contacts, a feature it shares with other social networks for scientists such as Elsevier's BiomedExperts and Google Scholar.
On September 8, 2010, ResearchGate announced the completion of its Series A financing. On February 22, 2012, ResearchGate announced the completion of its Series B financing. Currently, ResearchGate’s board of directors consists of Benchmark Capital general partner Matt Cohler, ResearchGate co-founder Madisch, and Founders Fund partner and PayPal co-founder Luke Nosek.
ResearchGate is said to be investigating ways to make money by providing job boards, conference boards for scientists and partnering with companies that manufacture and sell biotech lab equipment. 
Some scientists and researchers have expressed skepticism about the need for a social networking site. As quoted in Forbes, neuroscientist Bradley Voytek said “ResearchGate has its work cut out for them.” In his opinion, “researchers are quite conservative when it comes to adopting new technologies because time and attention are scarce commodities.” Voytek added that ResearchGate needs to “figure out how to get older, more experienced scientists to use their service. That’s a difficult task.”
An experiment conducted by journalist Beatrice Lugger showed that with just a few interactions on ResearchGate, her "RG score" would grow to the top 5%, indicating that the score as of now is barely indicative of scientific impact, and that most users interact even less.
