Overstory

What Overstory does

Overstory is an AI-powered vegetation intelligence SaaS company that helps electric utilities manage vegetation encroachment around transmission and distribution networks to prevent wildfires and power outages. The platform combines satellite and aerial imagery with machine learning models — including proprietary Fuel Detection, Ignition, Outage, and Scenarios models plus a computer-vision classifier that distinguishes up to 37 vegetation species — to produce tree-level risk prioritization across thousands of miles of power line. Inputs include weather data, asset age, terrain, wildfire maps, and historical outage and ignition records, synthesized into ranked worklists and cost-to-risk-reduction analyses for utility vegetation management teams. The platform is sold via annual subscriptions priced at roughly $90-$175 per mile, undercutting LiDAR-based alternatives at $350-$450 per mile.

The company was founded in 2018 in Lisbon, Portugal, by Indra den Bakker and Anniek Schouten (originally as 20tree.ai), and is now headquartered in Amsterdam with a U.S. office in Boston's Greentown Labs. Overstory serves 50+ investor-owned utilities, electric cooperatives, and European transmission operators, including six of the ten largest utilities in North America — PG&E, AEP, BC Hydro, ComEd, Oklahoma Gas & Electric, and Portland General Electric — plus Red Eléctrica de España and Hydro Ottawa. It reports enterprise sales motion, SOC 2 Type 2 certification, satellite imagery partnerships with Maxar, Planet Labs, and Airbus, and a strategic alliance with Watch Duty for real-time wildfire alerting.

Overstory has raised approximately $67.7M across six funding rounds from Seed (2019/2020) through a $43M Series B in November 2025 led by Blume Equity, with participation from Energy Impact Partners, B Capital, Semapa Next, Convective Capital, Pale Blue Dot, CapitalT, Moxxie Ventures, Bentley Systems, and others. Total headcount is in the 64-100 range across a remote-first team spanning Europe and North America, including software engineers, data scientists, in-house arborists, and wildfire specialists. Following co-founder Indra den Bakker's passing in 2024, Fiona Spruill became CEO; the company reported its strongest year in 2024 with revenue nearly quadrupling, customers doubling, and miles of power line analyzed tripling.

Core offering

Overstory sells an AI-powered SaaS Vegetation Intelligence Platform that fuses machine learning with satellite and aerial imagery to identify vegetation risk along electric utility transmission and distribution networks. The platform delivers tree-level precision risk prioritization, wildfire and outage prediction models, and species and health classification to help utilities prioritize vegetation management work, prevent wildfires, and reduce power outages. Pricing is subscription-based and quoted per mile of network analyzed.

Product overview

Overstory offers a unified Vegetation Intelligence Platform — a SaaS product combining AI and satellite imagery to help electric utilities manage vegetation risk and prevent wildfires and power outages. The platform is offered as a core product with multiple integrated modules: Wildfire Intelligence (including the proprietary Fuel Detection Model) provides wildfire-specific risk assessment; the Ignition Model and Outage Model (launched April 2026) predict where wildfires and outages will occur at tree-level precision; Overstory Scenarios enables real-time cost-to-risk comparison of resilience programs; and Vegetation Species Identification uses computer vision to classify up to 37 species along power line corridors. These modules share a common data layer (satellite/aerial imagery + AI) and collectively support use cases including cycle optimization, work quantification, targeted risk identification, and regulatory reporting.

Products and services

• Vegetation Intelligence Platform AI-powered SaaS platform that combines machine learning with satellite and aerial imagery to deliver vegetation risk analysis across transmission and distribution networks. Identifies vegetation encroachment, hazard trees, wildfire risk, and supports data-driven vegetation management decisions for electric utilities.
• Wildfire Intelligence Product within the Vegetation Intelligence Platform that identifies high-risk vegetation areas where utility sparks are most likely to ignite and spread wildfires. Includes a proprietary Fuel Detection Model and supports proactive wildfire mitigation for electric utilities.
• Ignition Model AI model that predicts where utility-caused wildfires are most likely to start, identifying specific trees, shrubs, and infrastructure at risk with tree-level precision by integrating historical fire data, equipment age, and weather information to deliver prioritized intervention lists.
• Outage Model AI model that predicts where power outages are most likely to occur, identifying specific vegetation and assets at risk with tree-level precision by combining historical outage data with weather and equipment data to prioritize vegetation management work.
• Overstory Scenarios Dynamic modeling tool that enables utilities to compare the cost and risk-reduction potential of different vegetation management and resilience programs in real time, replacing weeks of manual analysis and supporting cost-to-risk-reduction optimization.

Direct peers

• AiDash: AiDash is an AI-first SaaS company that uses satellite imagery and remote sensing to help electric utilities manage vegetation, storm response, and grid infrastructure. It is the most direct peer to Overstory, with overlapping customer base (US IOUs and cooperatives), similar product positioning (risk-based vegetation management), and a comparable sales motion.
• Sharper Shape: Sharper Shape provides drone-based inspection and 3D modeling services for electric utilities, including vegetation management and asset inspection. It competes with Overstory for utility vegetation management budgets but relies on aerial drone flights rather than satellite-derived analytics.
• LiveEO: LiveEO is a Berlin-based geospatial analytics company that applies satellite imagery to infrastructure monitoring, including vegetation encroachment along railway and power corridors. It is a direct competitor to Overstory in the European market using a similar AI + satellite approach.
• eSmart Systems: eSmart Systems is a Norwegian AI company that provides grid inspection, vegetation management, and asset analytics for utilities, leveraging drone, helicopter, and satellite data. It is a direct peer with comparable products for utility vegetation management in Europe and North America.

Broad incumbents

• Trimble: Trimble is a large geospatial technology company with deep utility relationships through its GIS, mapping, and field solutions. While not a specialist in vegetation intelligence, its broad portfolio and established utility sales channels could compete with or bundle Overstory's capabilities.
• Hexagon: Hexagon is a global leader in geospatial and industrial software, including HxGN Content Program aerial imagery used in electric and gas utility asset management. Its broad portfolio and scale make it a credible incumbent that could add vegetation analytics features competitive with Overstory.
• Esri: Esri's ArcGIS platform is the de facto GIS standard for electric utilities, providing the spatial data layer on which vegetation management workflows are built. As a broad incumbent, Esri could integrate or partner with capabilities that overlap with Overstory's analytics.
• Planet Labs: Planet Labs operates a high-cadence Earth observation satellite constellation that supplies imagery to Overstory and competes indirectly in vegetation monitoring. While primarily a data provider, Planet's vertical moves into analytics could compete with Overstory's downstream applications.
• Maxar Technologies: Maxar provides high-resolution satellite imagery and geospatial solutions used by governments, utilities, and infrastructure operators. As a core data partner to Overstory, Maxar could either deepen the partnership or extend into downstream vegetation analytics.

Emerging players

• Arboreal Solutions: Arboreal is an emerging tree management software platform focused on inventory, work planning, and risk modeling for utility vegetation management. It competes in adjacent workflow software but lacks the satellite-AI analytics layer that differentiates Overstory.
