Cracking the Code of the Nature Market with Matthew Jordan
RAMO Earth's Matthew Jordan joins the NatureBacked podcast to discuss the mission behind his platform, NatureOS—an operating system designed to enable nature-based solutions and help conservation projects thrive.
In a voluntary carbon market that is often described as "fragmented" and "confused," Matthew shares his journey from hands-on conservation work in Mozambique to building technological tools that bridge the gap between dreamers and dollars.
In this essential discussion, you will hear about:
The Wild West Carbon Market: Why the voluntary carbon market is struggling, facing "significant headwinds," and the challenges of high-integrity credit development.
The Funding Gap: The massive hurdle facing local developers—from small landowners to dedicated community groups—who have authentic, high-value projects but lack the institutional finance to professionalize.
The Rise of NatureOS: How Matthew and his co-founder, Miguel Correia (an AI data scientist), are building tools based on machine learning and remote sensing to help projects quickly assess feasibility, reduce risk, and get closer to "bankable" status.
Beyond Carbon: The emergence of new markets like Biodiversity Credits and how advanced technology can measure and monitor nature's services with a high degree of certainty, making nature one of the most valuable, yet currently unpriced, assets on the planet.
Human Potential vs. AI: Matthew's unwavering optimism, even after a career seeing ecosystems struggle, and his belief that the human capacity for dedication and change will ultimately beat the challenges faced by the climate and conservation worlds.

Beyond the Beach: Paige Roepers On How Ocean Ledger is Navigating Coastal Risk from Coral Reefs to Corporate Balance Sheets
What happens when a lifelong passion for the ocean meets the world of high finance? You get Ocean Ledger.
Paige, a marine biologist by heart who (surprisingly) transitioned to banking and consulting, shares the serendipitous journey that led her to co-found a company on a mission to change how we understand and manage coastal risks.
Prepare to have your perceptions challenged as Paige shows why oceans and the financial industry, far from being distant concepts, are intricately linked, especially when assessing global assets and exposures.
Key topics covered:
Origin of Ocean Ledger: Started from Paige's marine biology background, desire to work in ocean space beyond pure science, and serendipitous discovery of her co-founder's satellite mapping research after her time in banking.
Ocean & Banking Connection: Despite seeming disparate, Paige argues they're highly overlapped, as 70% of the world is ocean, impacting global assets and financial exposure.
Current Stage & Funding: Spun out 1.5 years ago, raised first venture funding in January, and are launching their first product for the financial services industry, starting with insurance.
B2B Sales Challenges: Acknowledged the slow pace of B2B sales in finance/insurance and strategies to de-risk (relationships, industry presence, focused product development, strategic opportunistic revenue).
Ocean Ledger's Product: Offers a software/dashboard for hazard assessment of storm surge and erosion, providing historical insight, quantifying existing defenses, and analyzing coastline changes for risk pricing and vulnerability assessment.
Target Markets: The initial focus will be on the US due to its high concentration of risk, with plans to expand to the Caribbean and Australia, where natural defenses are crucial.
Storm Surge Analysis: Explained that their USP is not just the physics model, but how the seabed depth, natural features (mangroves, rocks), and historical shoreline changes (erosion, beach nourishment) influence storm surge damage.
Satellite Monitoring: Utilizes satellite monitoring, capable of updating data every six days (though not always needed), providing high-frequency updates on coastline changes.
Long-Term Vision: Aims to be world-class in risk management for businesses and governments, bridging the gap between insurance/broking and insured clients (ports, developers) to unlock funding for exposure reduction through natural or built defenses.
Paige's Personal Connection: Reiterated her deep connection to the ocean, though she admitted it had been a few months since her last swim.
