Floodbase

# High-Level Overview

Floodbase is a climate adaptation technology company that provides satellite-based flood intelligence and parametric insurance solutions.[2] Founded in 2015 and based in New York, the company addresses a critical gap in global flood risk management: while 1.5 billion people face flood risk worldwide and $5.3 trillion in economic activity sits within 100-year floodplains, traditional flood insurance leaves most of this exposure uncovered.[2]

Floodbase serves three primary constituencies: insurance and reinsurance companies seeking to underwrite previously uninsurable flood risk; governments and humanitarian organizations responding to disasters; and corporate risk holders protecting business continuity. The company's core product is an end-to-end platform that combines near real-time flood mapping with parametric insurance design and triggering mechanisms, enabling policies that pay out based on flood magnitude rather than individual property damage assessments.[5] This approach allows payouts within days of an event, giving policyholders discretion over fund deployment rather than waiting for traditional claims processes.

# Origin Story

Floodbase was founded in 2015 by Bessie Schwarz and Dr. Beth Tellman while they were pursuing Master's degrees at Yale University.[2] Both founders had direct experience working with climate-vulnerable communities and recognized how data scarcity directly contributed to financial inequity during climate disasters. Their initial project—built as a side effort to improve disaster aid allocation in El Salvador and New York—caught the attention of Google, which flew them to Mountain View for a presentation and subsequently funded them to develop the full platform.[2]

The company's scientific credibility was established early: Floodbase's research on satellite flood tracking appeared on the cover of *Nature* in 2021, and the Flood Intelligence Platform has since been adopted by the United Nations and multiple national governments for disaster response operations.[2] This trajectory from academic research to operational deployment across humanitarian and commercial sectors demonstrates the founders' ability to bridge science and practical application.

# Core Differentiators

• Advanced satellite detection technology: Floodbase's proprietary MODIS sensor algorithm significantly improves water detection in challenging terrain (sloped areas where water flows downhill) while minimizing false positives from terrain shadows, and can process tens of thousands of images simultaneously.[1]

• Multi-source data integration: Unlike competitors relying on models or one to two satellites, Floodbase leverages seventeen observational sources combined with hydrological, meteorological, and ground-based data to ensure consistent monitoring regardless of cloud cover—a critical advantage for parametric insurance in the 70% of global locations underserved by traditional flood maps.[5]

• Parametric insurance innovation: The company has assembled a carrier panel and developed the operational infrastructure to enable large-area flood insurance products that pay based on flooding magnitude rather than individual property assessments, fundamentally changing how flood risk is insured.[5]

• Established institutional partnerships: Floodbase counts Swiss Re Corporate Solutions, Liberty Mutual Re, and AXA Climate among its reinsurance partners, while also supporting FEMA, the UN, and major media outlets like The New York Times.[1]

# Role in the Broader Tech Landscape

Floodbase operates at the intersection of three converging trends: climate adaptation necessity, parametric insurance innovation, and satellite data accessibility. As flood losses reached $80 billion in 2021 alone and climate projections suggest $15 trillion in economic activity will face flooding risk by 2040, traditional insurance models are proving inadequate.[2] The company is pioneering a new category—climate adaptation technology that makes previously uninsurable risk manageable through data science and financial innovation.

The timing is critical: regulatory pressure on insurers to address climate risk, corporate demand for business continuity solutions, and government recognition of parametric insurance's efficiency in disaster response are all accelerating adoption. Floodbase's influence extends beyond its direct customers; by demonstrating that satellite-based flood intelligence can power insurance products at scale, the company is validating an entire market category and attracting capital to the broader climate tech ecosystem.

# Quick Take & Future Outlook

Floodbase is positioned to become the foundational data layer for global flood risk management. Recent product launches—including an on-demand U.S. flood mapping tool for insurers (August 2025) and parametric flood coverage for New Orleans businesses in partnership with Yokahu (April 2025)—signal expansion from reinsurance into direct commercial and municipal markets.[4]

The company's trajectory suggests three likely developments: geographic expansion beyond initial focus areas, deepening integration with insurance platforms to reduce friction in policy design, and potential expansion into adjacent climate risks (precipitation, drought) leveraging the same satellite infrastructure. As climate volatility increases and traditional insurance models face pressure, Floodbase's ability to make previously uninsurable risk quantifiable and insurable could reshape how the global economy adapts to climate change—transforming the company from a specialized data provider into essential climate infrastructure.
