Aarhus GeoSoftware

Aarhus GeoSoftware is a Danish geophysical software company based in Aarhus. It was established in 2015 as a private spin-off from the HydroGeophysics Group at Aarhus University, starting with a group of four people. The company develops professional software solutions for the processing, inversion and visualization of geophysical data, with a focus on data acquired by electromagnetic and electrical instruments. Its principal products are the Aarhus Workbench platform and the SPIA software package. Aarhus Workbench is built on a GIS platform that supports processing and visualization of data in slices and sections. Its feature set includes cloud-based inversion through Aarhus Cloud Inversion, TEM inversion with induced polarization (IP) effects using Cole-Cole or Maximum Phase Angle approaches, import of ERT/IP, TEM, FEM, borehole lithology and geophysical logs into a single workspace, a 3D viewer for models, boreholes, sections and grids, a PDF reporting tool, QC tools, a color scale editor and borehole log handling. The company also maintains the Res2DInv and Res3DInv resistivity and IP inversion software line, with releases such as Res2DInv 2026.2 and Res2DInv & Res3DInv 2025.2. The software is applied to practical earth, environment and energy problems. Resistivity modelling can help identify groundwater, locate mineral deposits and define drilling targets, while civil engineering users apply the tools to questions such as locating bedrock. The company cites a Nordic highway project that reduced drilling by 30 percent using AEM, Workbench and machine learning. Aarhus GeoSoftware is now part of Seequent, the geoscience software group, and positions itself as helping customers solve earth, environment and energy challenges. At the time of its about-page description the company had grown to ten employees, including software developers, geophysicists and geologists. Toke Højbjerg Søltoft is the CEO and Stinne Høst is the CTO.

Aarhus GeoSoftware was established in 2015 as a private spin-off company from the HydroGeophysics Group at Aarhus University in Denmark. It began with a group of four people. The company was founded to commercialize software for processing, inversion and visualization of geophysical data, particularly data collected with electromagnetic and electrical instruments. Over the following years the company grew to ten employees, a team that includes software developers, geophysicists and geologists. Its product line expanded around the Aarhus Workbench platform, a GIS-based environment for processing and visualizing data in slices and sections, and the SPIA software package. Workbench capabilities accumulated features such as Aarhus Cloud Inversion for running large inversion jobs in the cloud, TEM inversion with IP effects using Cole-Cole or Maximum Phase Angle methods, import of ERT/IP, TEM, FEM, borehole lithology and geophysical logs into a single workspace, a 3D viewer, a PDF reporting tool, QC tools, a color scale editor and borehole log handling. The company also maintains the Res2DInv and Res3DInv resistivity and IP inversion software, with releases including Res2DInv & Res3DInv 2025.2 and Res2DInv 2026.2. Aarhus GeoSoftware is now part of Seequent, the geoscience software group, and describes itself as helping customers solve earth, environment and energy challenges. Its software is used in applications such as groundwater identification, mineral exploration, drill target definition and civil engineering questions like locating bedrock.
