wiki 6 26 ResearchGate - Wikipedia
...ResearchGate has been criticized for failing to provide safeguards against "the dark side of academic writing", including such phenomena as fake publishers, "ghost journals", publishers with "predatory" publication fees, and fake impact ratings.[43] It has also been criticized for copyright infringement of published works.[44][9][45]

History
ResearchGate was founded in 2008[11] by virologist Ijad Madisch, who remains the company's CEO,[4][3] with physician Sören Hofmayer, and computer scientist Horst Fickenscher.[13] It started in Boston, Massachusetts, and moved to Berlin, Germany, shortly afterwards.[14]
The company's first round of funding, in 2010, was led by the venture capital firm Benchmark.[21] Benchmark partner Matt Cohler became a member of the board and participated in the decision to move to Berlin.[22]
The website began with few features, and developed based on input from scientists.[3] From 2009 to 2011, the number of users of the site grew from 25,000 to more than 1 million.[12]
A second round of funding led by Peter Thiel's Founders Fund was announced in February 2012.[22] On June 4, 2013, it closed Series C financing arrangements for $35M from investors including Bill Gates.[23][24]
The company grew from 12 employees in 2011 to 120 in 2014.[3][14] As of 2016, it had about 300 employees, including a sales staff of 100.[25]
ResearchGate's competitors include Academia.edu, Google Scholar, and Mendeley,[4] as well as new competitors that emerged in the last decade like Semantic Scholar. In 2016, Academia.edu reportedly had more registered users (about 34 million versus 11 million[25]) and higher web traffic, but ResearchGate was substantially larger in terms of active usage by researchers.[4][5] 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.[4][5] In a 2015–2016 survey of academic profile tools, about as many respondents have ResearchGate profiles and Google Scholar profiles, but almost twice as many respondents use Google Scholar for search than use ResearchGate for accessing publications.[6]
Madisch has said the company's business strategy is focused on highly targeted advertising based on analysis of the activities of users, saying "Imagine you could click on a microscope mentioned in a paper and buy it", and estimating the spending on science at $1 trillion per year under the control of a "relatively small number of people".[4]
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.[26][27] Losses increased from €5.4m in 2014 to €6.2m in 2015, but ResearchGate's CEO expressed optimism that they would break even eventually.[28]
ResearchGate, Elsevier and American Chemical Society settled their lawsuit on 15 September 2023.[29][30]
As of January 2023, ResearchGate has partnered with Sage to distribute open access content.[31]
