Orthant is a collection of specialized software companies dedicated to serving industries where performance, precision, and compliance are paramount.

As part of Carina—and by extension, Constellation Software Inc.—we embrace a buy-and-hold philosophy. We acquire established software businesses, maintain their operational independence, and provide them with the resources and strategic support necessary for sustained, long-term growth.

Our portfolio encompasses a diverse array of technical domains, including:

• Welding documentation

• Pressure vessel and piping design

• Finite element and stress analysis

• Forestry contract and inventory management

• Geospatial monitoring for infrastructure and land

We continue to expand into adjacent and complementary areas, guided by a deep respect for industry expertise and the operational realities of complex markets.

Each business within the Orthant portfolio is a leader in its respective field. Collectively, we support professionals with tools that enhance decision-making, ensure safety, and deliver enduring value.
