Overstory raises $43 million to help utilities avoid wildfires with AI. Emanuela Hawker November 26, 2025 AI-powered grid resilience platform Overstory announced that it has raised $43 million in a Series B round, with the new capital aimed at supporting the development of its AI-based risk models to help utilities prevent wildfires. Founded in 2018, Amsterdam-based Overstory's platform uses high-resolution satellite data and AI to enable utilities to optimize vegetation management, to help prevent wildfires and reduce outages, pinpointing risk at a tree-by-tree level. The company works with more than 50 investor-owned utilities, cooperatives, and municipalities across North and South America and Europe. The company said vegetation is the leading cause of outages and wildfires, with demand for more accurate vegetation management growing alongside rising tree mortality, higher labor expenses, and more extreme weather events. "Utilities are on the front lines of keeping communities safe, and they're eager to use the best data available. When we talk about how satellites and remote sensing can identify dying trees and wildfire risk, they lean in." Alongside the funding news, Overstory launched the latest version of its Wildfire Intelligence product. The update includes a proprietary Fuel Detection Model designed to help utilities identify the parts of their networks where available fuels pose the greatest ignition and spread risk. The company said the tool offers more specific, action-oriented insights than publicly available fire-risk maps commonly used in the sector. The funding round was led by Blume Equity, with participation from Energy Impact Partners and existing investors including B Capital, Semapa Next, Pale Blue Dot, CapitalT, Convective Capital, Bentley Systems, MCJ and Moxxie Ventures. Michelle Capiod, Co-Founding Partner at Blume Equity, said: "The companies that will drive the greatest impact on our planet are those that deliver climate solutions with real economic value. This is exactly the kind of scalable, high impact climate solution we're proud to support."

Existing investors, B Capital, Semapa Next, Pale Blue Dot, CapitalT, Convective Capital, Bentley Systems, MCJ, and Moxxie Ventures also participated in this round. James Sprinz, Principal at Energy Impact Partners, says, "Utilities are at a pivotal moment, facing more extreme weather events every year. Overstory is tackling this challenge in a way that utilities can act on immediately, making sense of satellite data to spot the exact tree to trim, pole to clear, or asset to replace." Michelle Capiod, co-founding Partner at Blume Equity, adds, "The companies that will drive the greatest impact on our planet are those that deliver climate solutions with real economic value. Overstory exemplifies this - transforming satellite data into actionable insights that help utilities both prevent climate-related disasters and drive operational efficiencies." "Their customer-first approach and leadership in AI have enabled them to develop cutting-edge, yet highly practical, solutions that deliver a tangible return on investment. This is exactly the kind of scalable, high-impact climate solution we're proud to support at Blume Equity." Overstory plans to use the funds to develop its AI-based risk models, expand its wildfire prevention tools, and expand its operations internationally. Reducing wildfire and outage risks in utility operations. Founded in 2018 by Indra den Bakker and Anniek Schouten, Overstory aims to use artificial intelligence to help utilities manage vegetation and wildfire risk. Overstory introduced a Fuel Detection Model to help utilities identify locations where vegetation poses the greatest risk of fire ignition and spread. The model uses satellite imagery to locate high-risk areas, enabling utilities to take specific actions to reduce wildfire potential. Utilities have previously relied on publicly available fire risk maps that provide broad assessments of regional risk. Overstory's platform provides detailed data to help utilities prioritise resources and implement a targeted maintenance strategy. Fiona Spruill, CEO of Overstory, says, "Utilities are on the front lines of keeping communities safe, and they're eager to use the best data available. When we talk about how satellites and remote sensing can identify dying trees and wildfire risk, they lean in." "We're grateful to our forward-thinking investors for supporting this next chapter - expanding our intelligence product to address storms and wildfires to help utilities build a more resilient and reliable grid." A new Chief Operating Officer. Over the past seven years, Overstory has been operating and expanding its business, and during that time, it has provided its services to six out of the ten largest utility companies in the Americas. The company has grown its team to more than 80 people, covering roles from machine learning and data science to arboriculture and wildfire management. Overstory's next phase will be guided by its new Chief Operating Officer, Tamara Mendelsohn. She is a former Eventbrite CMO who has experience scaling companies from seed stage to IPO.
