Plum Analytics

Plum Analytics is a Philadelphia, Pennsylvania-based altmetrics company dedicated to measuring the influence of scientific research.

History
It was founded in 2011 by Andrea Michalek, who is its current president, and Mike Buschman. It was acquired by Elsevier in February 2017, which purchased it from EBSCO Information Services for an undisclosed amount. Its metrics were immediately incorporated into Elsevier's existing products, including Mendeley and Scopus.

PlumX
Plum Analytics is best known for PlumX, which was the company's first product. PlumX is an online tool that provides altmetrics for peer-reviewed journal articles and other scholarly works by aggregating information from different sources including Wikipedia. In August 2015, Plum Analytics released the "PlumX Suite", which consists of five separate products: Metrics, Dashboards, +Grants, Benchmarks, and Funding Opportunities.
