Sigma Geoscience

Our Mission

We started Sigma Geoscience because we felt that the current options for field data collection and structural analysis were not fitting our vision of what software could be for field and structural geologists. Geologists today routinely stitch their workflow together from a handful of free academic tools and one or more expensive commercial packages — one for stereonets, another for density, a third for the map view, a fourth for field capture.

Our mission at Sigma is to provide cutting-edge, fast, and intuitive software that allows users maximum functionality through an integrated, one-stop-shop application — from the outcrop to the stereonet to the report — at a price that respects the geologists who actually use it.

Our Vision

We envision Sigma Geoscience as the source for quality structural analysis software — software that is genuinely useful and that moves seamlessly with the way geologists actually work, integrating field observations and structural data into a single, fluid workflow.

Meet the Founders

Sigma Geoscience was founded by two structural geologists who met in grad school at Montana State University and have spent the years since working on opposite sides of the geoscience world — one in industry, one in academia.

Julian Stahl

Co-founder · CEO

Julian had the initial vision for Stereogram and serves as CEO of Sigma Geoscience. He brings a structural geology background combined with deep experience commercializing geoscience technology.

Julian holds a Bachelor’s in Geology from UC Santa Barbara and a Master’s in Structural Geology from Montana State University, where he conducted structural analysis in the Bighorn Basin of Wyoming.

After grad school, Julian worked at OnX Maps in Missoula, Montana, before moving into the energy-tech sector. Today, he leads worldwide commercial strategy at Rogii as VP of Global Sales, where Rogii operates one of the most widely used geosteering platforms in the industry.

Jacob Thacker

Co-founder · CTO

Jacob is CTO of Sigma Geoscience and leads technical development of Stereogram.

Jacob holds a Bachelor’s in Geology from Cleveland State University and a Master’s in Structural Geology from Montana State University, where he studied a fault in the Stillwater Complex of the Beartooth Mountains. He earned his PhD from the University of New Mexico, conducting research on intracontinental tectonism using structural analysis, basin analysis, and thermochronology.

He subsequently worked as a Field Geologist for the New Mexico Bureau of Geology, and since 2022 he has been an academic geologist based in Billings, Montana, currently teaching for Rocky Mountain College.
