Seattle startup Trovares has raised another $1.35 million to help boost its graph analytics business.

The 9-person company launched in 2015 and is led by Jim Rottsolk, former CEO at Cray, the Seattle supercomputer company acquired by HPE for $1.3 billion in 2019.

Graph analytics consists of analyzing data in a graph format, with nodes and connections between them. The idea is to help companies run search queries and find patterns within various databases.

Trovares customers include the Department of Defense; the University of Warsaw; and other large enterprise companies.

Rottsolk co-founded Tera Computer in 1988 and acquired the Cray Research arm of Silicon Graphics, merging those assets to form Cray Inc. He stepped down in 2006 and joined Microsoft Research before founding Trovares five years ago with David Haglin, a former chief scientist at the Pacific Northwest National Laboratory (PNNL).

The most recent cash infusion is part of a larger $1.5 million round from existing investors, including Seattle attorney Rich Padden of Carney Badley Spellman.

Trovares raised a separate $2.5 million round in 2019.
