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.
Kerem Ozkay
Kerem Ozkay is the CEO of Carbon Health, the modern primary and urgent care chain. An aerospace engineer turned marketer turned operator, he ran growth and operations at Carbon for years before founder Eren Bali handed him the top job in August 2024. He now steers the company through a Chapter 11 restructuring designed to refocus on its hybrid care model and homegrown EHR.
Laurence Allen
Laurence Allen is the co-founder and CEO of Terranova, a Berkeley-based startup building autonomous terraforming robots that lift flood-prone land out of harm's way by injecting wood waste slurry deep underground. A UC Berkeley Mechanical Engineering graduate (2024) who conceived the idea during a 2021 SpaceX internship, Allen launched the company — originally called Levitree — to save his own hometown of San Rafael, California, which floods to waist depth several times a decade. Terranova closed a $7M seed round in late 2025 at a $25.1M valuation led by Congruent Ventures and Outlander, and can lift one acre of land by one foot per day at a fraction of the cost of traditional seawalls. Allen was named to the 2026 Forbes 30 Under 30 list in Energy & Green Tech, took a leave from his Stanford master's program to scale Terranova full-time, and entered 2026 actively pursuing commercial elevation projects across the Bay Area for flood prevention, development, and wetland restoration.
