Today, thinning a forest means sending two 20-ton machines in to remove trees that weigh about 80kg on average. The trails they need clear-cut roughly 20% of the forest, just for access.
Air Forestry does it from the air instead. A six-metre, six-armed drone selects a tree, grabs it from the top, strips the branches using gravity, cuts the trunk with an electric chainsaw, and lifts the whole tree out to the roadside. It’s the same end product the industry already pays for, without a single track through the forest.
Co-founder and CEO Caroline Walerud has spent 15 years in startups and deep tech investing. She sold bread door to door as a teenager, studied natural sciences at Cambridge, and founded Volumental, which has now scanned more than 60 million feet. She then invested in deep tech through her family’s office before jumping back in as an operator.
In this episode, Colin Brown and Caroline cover:
- What selling bread door to door teaches a founder
- Volumental: starting with a technology instead of a problem, and what that cost
- Investor vs operator: the filter of “would I work with this team two days a week for 15 years?”
- Forestry 101: why commercial thinning matters for forest health, carbon and wildfire risk
- The world’s first air harvest
- How two operators supervising 6–12 drones could deliver a huge productivity increase
- Why forestry is a regulatory sweet spot for autonomy
- Building a vertically integrated drone, tool and software stack in Uppsala
