Sigma5 — Measurement Technology for Environmental Industries

Features and technology

Hyperspectral world models unlock new capabilities and automations

A full stack platform for sensing, world models, and AI reasoning layers.

Perception

We see what RGB and LiDAR can't

Spectral signatures sense and differentiate transparent and specular objects, textures for grasp planning, crop stress in agriculture, gas and fluid leaks, and stage of corrosion.

AI/ML

Accelerate and enhance existing models

Our platform provides sim-training for material reasoning and powers it for RGB inference.

World Data

Compounding data and models

Sigma5 data and models are continuously improved for understanding composition, condition, and material reasoning.

Deployment

Every industry and application are improved

Our platform turns impossible and costly measurement into everyday inputs — across agriculture, energy, infrastructure, and robotics.

Our Mission

Technology to measure and understand the world

Sigma5 is founded by a team of scientists and technologists with a clear focus: helping industries meet the moment with tools to improve performance and reduce risk.

At the heart of our mission is a commitment to accelerating the global shift toward a resilient future. We are creating cutting-edge technology to empower industries, governments, and communities to increase yield and economic growth.

Technology, thoughtfully designed and responsibly deployed, is one of the most powerful tools in the fight for energy security. That’s why we focus on real-world applications that drive efficiency, transparency, and action across supply chains and energy systems.
