## About

Based in Massachusetts, US, and co-founded by Hudson Gilmer (CEO) Jonathan Marmillo (CPO), and Nathan Pinney in 2018, LineVision, Inc. operates as a provider of electric utility tools. In September 2026, LineVision, Inc. raised USD 37.5 million in series D funding co-led by Centaurus Capital and New System Ventures, with participation from National Grid Partners.

LineVision’s non-contact sensor and patented software solutions, as well as transmission line monitoring and asset management solutions, provide Dynamic Line Ratings (DLR) and transmission line analytics, accelerating the Net Zero Grid. The company's flagship product, LineVision LUX™, is a sole non-contact sensor, providing real-time measurements without the need for physical contact with live lines. This technology, backed by IEEE and CIGRE methodologies, contributes to the safest DLR calculations. LineVision's software suite, including LineRate® Suite, LineAware®, and LineHealth®, complements its sensor technology, offering utilities comprehensive visibility into line capacity, health, and performance. The company's methodologies, incorporating machine learning and Computational Fluid Dynamics, guarantee 99.5% DLR availability.  The firm, as of December 2023, has helped its clients avoid 1,391,442 million ton of CO2, and some of its clients include National Grid, DLC, New York Power Authority, Xcel Energy, etc.

LineVision, Inc. generates revenue through the subscription, deployment, and support of transmission grid intelligence solutions for electric utilities and transmission system operators. The company provides Dynamic Line Ratings (DLR), transmission line monitoring, grid analytics, asset optimization, and capacity enhancement software that enables utilities to improve transmission reliability, increase network utilization, and support grid planning. Revenue is derived from software subscriptions, recurring analytics and monitoring services, hardware-enabled sensing solutions, implementation and integration services, and ongoing maintenance and technical support contracts with utility customers.

The company will use the September 2026 funding to accelerate the global deployment of its transmission grid intelligence platform, expand adoption of its Dynamic Line Ratings (DLR) technology, and strengthen its position as a leading provider of grid-enhancing technologies. The investment is expected to support the company's growth as utilities increasingly seek solutions to optimize existing transmission infrastructure, unlock additional grid capacity, improve reliability, and address rising electricity demand driven by AI data centers, electrification, and advanced manufacturing.
