Berlin-based ResearchGate, a LinkedIn-type site for scientists, today revealed that it has received $52.6 million from Microsoft co-founder Bill Gates and a wide spectrum of other investors in a funding round.
The investment round closed in 2015, but it’s just now being reported due to German regulatory requirements.
New investors for this round included the Wellcome Trust, Goldman Sachs Investment Partners and Four Rivers Group, with participation from the likes of Hollywood actor Ashton Kutcher and French entrepreneur Xavier Niel.
Gates re-upped after investing in a previous $35 million round for ResearchGate. Benchmark, Founders Fund and Tenaya Capital are among the other investors who added to their previous stake.
