  • Floodbase

    Participated · Equity · Feb 2025

    Floodbase is a parametric platform that insures uncovered economic flood risk, continuously monitoring flooding worldwide using more than a decade of peer‑reviewed science. Its platform powers flood insurance programs for corporate and public‑sector clients and is used by leading re/insurers including Swiss Re Corporate Solutions, Liberty Mutual Re, and AXA Climate. Since its 2023 Series A, Floodbase has operated across 40+ countries and enabled more than 9,000 flood insurance policies. The company also supports FEMA, the UN, and The New York Times to identify and respond to major flood events. Floodbase plans to accelerate development of new flood insurance programs and cement its position as the industry standard for this emerging category of flood insurance. Co‑founded by Bessie Schwarz and Dr. Beth Tellman, Floodbase has raised $17 million in venture capital to date and emphasizes rapid, flexible liquidity to cover broader economic losses from floods. Floodbase is a New York-based climate adaptation technology company led by CEO Bessie Schwarz that provides precise, near real-time data and analysis on flooding and flood risk. Its platform is powered by 15 satellites, machine learning, and on-the-ground data to deliver satellite imagery, historical data, and modeling. Floodbase produces precise predictions of flood locations and severity and near-real-time measurements of flooding events. The company supplies data to insurance companies and governments to inform flood preparedness, recovery decisions, and parametric policy payouts. Floodbase raised $12M in a Series A and intends to use the funds to make parametric flood insurance policies available worldwide, protecting consumers and supporting climate change adaptation. Its combination of technologies can create new options for the previously uninsured.

  • Mast Reforestation

    Led · Series B · Feb 2025

    Mast Reforestation provides post-wildfire reforestation services and is integrating biomass burial (Biomass Carbon Removal & Storage, BiCRS) to generate restorative carbon removal credits. The company is launching its first restorative biomass burial project, Mast Wood Preserve MT1 in central Montana, with burial activities planned for 2025 and expected generation of up to 30,000 tonnes of removal credits through 2026, available for presale. Mast pairs burial with restoration using native species grown from wild-collected seed in-house and manages two large nurseries, Silvaseed and Cal Forest, producing an average of 36 million seedlings annually. The MT1 project is designed as a geotechnically engineered, anoxic chamber protected under a 100-year easement, and Mast has submitted the project for a BeZero rating while pursuing registration and future verification with Puro.earth. Since 2020 Mast has specialized in carbon-financed reforestation across the U.S. and Canada and has restored thousands of acres in California, Montana, and Oregon. The company lists buyers such as Shopify and TIME CO2 and is using recent funding to scale its restorative reforestation and durable carbon removal efforts. DroneSeed’s core product is an automated drone system that delivers engineered seed packets and, when needed, applies treatments to accelerate forest recovery after wildfires. Its drones map terrain, select optimal planting sites, and deploy squirrel-resistant, nutrient-filled seed “pucks,” while collecting granular data for auditing and growth tracking. The company has expanded operational capability through FAA approvals for swarms and beyond-line-of-sight flight, and has grown its team to over 60 employees. To address nursery and seed shortages it acquired Silvaseed, a roughly 150-year-old seed supplier, and committed to expanding that seed-sorting and seedling-growing capacity. DroneSeed now grows millions of seedlings annually and says it is doubling capacity, positioning itself as a vertically integrated, one-stop reforestation provider. Financially, the company is pursuing carbon futures (“ex ante” credits) as a funding mechanism to accelerate projects and provide upfront capital for large-scale restoration. The recent funding round is intended to scale operations, expand nursery capacity, and support its integrated reforestation and carbon-finance model.

  • Twelve

    Led · Series C · Sep 2024

    Twelve develops technology to convert captured CO2, water and renewable energy into chemicals, fuels and other products, including sustainable aviation fuel (SAF) branded E-Jet®. The company’s AirPlant™ One SAF plant in Moses Lake, Washington is expected to begin production in 2025. Twelve says its E-Jet fuel, made from biogenic CO2, can achieve lifecycle emissions up to 90% lower than conventional fossil jet fuel. The company is focused on defossilizing manufacturing processes with an initial emphasis on aviation customers such as Alaska Airlines and International Aviation Group (parent of British Airways). Led by CEO Nicholas Flanders and based in Berkeley, Twelve is advancing deployment of multiple AirPlants across the U.S. to scale supply of its products. Recent financing is intended to accelerate those buildouts and commercialization plans. Twelve converts captured CO2 into building blocks for materials, chemicals, fuels and consumer products, and says these products match the quality of fossil-derived alternatives. Internally developed products include CO2-derived sunglasses (priced at $495) and carbon-neutral fuels, and the company plans to integrate its technology into partner supply chains and operations. Twelve intends to build an industrial-scale carbon-transformation platform by installing reactors at partnered manufacturing locations to convert emitted CO2 directly into usable products. The company has partnerships with Mercedes‑Benz, Procter & Gamble, Shopify, NASA and the U.S. Air Force, and cites potential partners among CO2-capture firms such as Global Thermostat and Shell. Twelve declined to disclose how many products it has sold or any revenue figures. The company acknowledges a carbon footprint from manufacturing that it says is paid back quickly once running, though it is unclear whether that accounting includes Scope 3 emissions. Twelve develops proprietary catalyst and electrolysis technology that transforms CO2 into critical chemicals, materials and fuels conventionally made from fossil feedstocks. Its carbon transformation devices are designed to drop into existing manufacturing processes and integrate at any scale to produce CO2Made products. The company is partnering with brands and organizations including Mercedes‑Benz, Procter & Gamble and NASA to replace petrochemical feedstocks across automotive, household, apparel and other industries. Twelve says replacing fossil feedstocks in its target applications could address nearly 10% of global carbon emissions. The company raised $57 million in a Series A to expand its team, partnerships and scale its technology. Twelve is taking pre-orders for an industrial-scale carbon transformation module as it prepares to commercialize its devices.
