Researchgate.net Biography & Web Analysis

ResearchGate is a European commercial social networking site for scientists and researchers to share papers, ask and answer questions, and find collaborators. According to a 2014 study by Nature and a 2016 article in Times Higher Education, it is the largest academic social network in terms of active users, although other services have more registered users, and a 2015–2016 survey suggests that almost as many academics have Google Scholar profiles.
ResearchGate was founded in 2008 by virologist Dr. Ijad Madisch, who remains the company's CEO, with physician Dr. Sören Hofmayer, and computer scientist Horst Fickenscher. It started in Boston, Massachusetts, and moved to Berlin, Germany, shortly afterwards. The company's first round of funding, in 2010, was led by the venture capital firm Benchmark. Benchmark partner Matt Cohler became a member of the board and participated in the decision to move to Berlin.
In November 2015 they acquired additional funding of $52.6 million from a range of investors including Goldman Sachs, Benchmark Capital, Wellcome Trust and Bill Gates, but did not announce this until February 2017. Losses increased from €5.4m in 2014 to €6.2m in 2015, but ResearchGate's CEO expressed optimism that they would break even eventually.
In 2016 Academia.edu reportedly had more registered users (about 34 million versus 11 million) and higher web traffic, but ResearchGate was substantially larger in terms of active usage by researchers. The fact that ResearchGate restricts its user accounts to people at recognized institutions and published researchers may explain the disparity in active usage, as a high percentage of the accounts on Academia.edu are lapsed or inactive.
As of 2018, it has more than 15 million users, with its largest user-bases coming from Europe and North America. Most of ResearchGate's users are involved in medicine or biology, though it also has participants from engineering, computer science, agricultural sciences, and psychology, among others.
