Climate First

What Climate First does

Climate First is a small, privately held firm headquartered in London, United Kingdom, with 1-10 employees. The firm operates in the climate risk advisory space with a specific focus on property resilience assessment for real estate, addressing the growing need to evaluate buildings' ability to withstand natural hazards including hurricanes, wildfires, floods, and extreme heat. Its primary use case is providing climate risk due diligence to the Real Estate Services segment, an early-adopter category for standardized climate resilience evaluation in a market context where insured losses from natural catastrophes averaged over $100 billion annually between 2020 and 2023.

The company's core offering is built around ASTM International's E3429-24 Property Resilience Assessment (PRA) standard, released in October 2024. Climate First is among the first cohort of firms — alongside Intertek and RWDI — to incorporate this newly formalized industry standard into its service delivery, providing clients with a structured framework for climate-resilient real estate due diligence. No proprietary products, software platforms, technology stack, pricing models, or named customers are disclosed in the available source material.

Revenue mechanics, pricing structure, and go-to-market motion are not disclosed. No funding rounds, management team, certifications, patents, M&A activity, or geographic footprint beyond the London base have been reported. The firmographic description labels the entity as a venture capital firm, while the partnership and segment data characterize it as a climate advisory / standards-based assessment provider; this ambiguity, combined with minimal public information, constrains deeper analysis of the business model.
