Mast Reforestation Learned Planting Trees Wasn’t the Hard Part - Financing the Forest Was
Mast began with a fleet of seed-firing drones. Then it discovered the expensive truth: after a megafire, the real bottlenecks are native seed, nursery space, dead wood and patient capital - so it bought the supply chain and buried the business model underground.
Terranova
Terranova is a Berkeley-born climate-tech and robotics startup building car-sized autonomous robots that inject a wood-waste slurry deep underground to lift flood-prone land out of harm's way - no seawalls, no surface disruption. A single 'mothership' coordinating three injection rovers can raise about one acre by one foot per day, while the buried biomass becomes a durable carbon sink that can be sold as carbon credits. Founded by UC Berkeley mechanical engineer Laurence Allen to save his hometown of San Rafael, California, the company raised a $7M seed round in November 2025 and plans its first San Rafael pilots in 2026.
