PearTree

PearTree develops a browser-based phylogenetic tree viewer for exploring and annotating evolutionary trees. The software, also called PearTree, is the successor to FigTree, rewritten to run entirely in the browser or as a native desktop application on macOS, Windows and Linux. It is designed for genomic epidemiology and displays large NEXUS and Newick trees with rich visual annotations.

All processing is performed locally on the user's machine, with no data uploaded to any server - a design choice that places data privacy at the centre of the product. The company's technical work spans browser-based software, cross-platform desktop application development and evolutionary tree visualization, serving researchers in bioinformatics, evolutionary biology and life sciences research.

The team focuses on open source projects and peer-to-peer software development solutions, and describes itself as a group of developers working across these domains. Further details on the company's founding, size and funding are not publicly stated.
