Academia.edu, the academic world’s platform for sharing research papers, has grown to 175 million users and is nearing half of the world’s academic research content. With around 100 million papers written since the 1600s, Academia aims to make every research paper ever written freely available on the internet. This growth has attracted $23 million in Series D funding led by Tencent, bringing the total investment raised to $63 million. True Ventures and Greyrock Investments also participated in the funding round. With this new funding, the company aims to expand into allowing academics to be peer-reviewed and published in journals hosted on the Academia platform.
