Overstory CEO Fiona Spruill

As a new year unfolds, 2025 has already brought devastating natural disasters. From blizzards to wildfires, climate chaos is impacting our neighbors and communities in real time. My heart goes out to the people of Los Angeles for the profound losses they suffered last month, and for the difficult path of rebuilding that lies ahead. This devastation brings to mind a tragedy that struck even closer to home in 2018.

I remember driving through Oakland that year, watching ash fall from the sky as the Camp Fire ravaged Paradise, California. That fire, still the deadliest and most destructive in California’s history, was sparked by vegetation coming into contact with power lines-- a common risk that, coupled with dry conditions, strong winds, and human activity, can ignite a wildfire. That same year, at least 17 additional wildfires in California were triggered by power lines.

Across the country and around the world, utilities face ongoing challenges from vegetation. The diversity of trees and their unique characteristics make it difficult to forecast where or when they might encroach on power lines. Traditional monitoring solutions like trucks, helicopters, and even drones cannot effectively or cost efficiently analyze the nearly 7 million line-miles of transmission and distribution that cover the US alone. 

In response, Indra Den Bakker and Anniek Schouten founded Overstory in 2018 — a software company that partners with utilities to predict and prevent wildfires caused by vegetation encroachment. Powerhouse Ventures is proud to be an early investor in Overstory, joining the team in 2020 via their seed round. It's been inspiring to watch the company grow, even in the face of immense loss.

Overstory’s founding CEO Indra tragically passed away in October of last year after a devastating battle with cancer, but his vision lives on. In a world where climate risks are increasing, Overstory's work is more critical than ever. Today, Overstory’s CEO Fiona Spruill and her team are continuing to manifest Indra and Anniek’s vision to reduce wildfire risks and make our grid resilient. This episode is a tribute to Indra, Anniek, and all that they’ve built together.
