Rigorous economics, built for the field.
QuantEco Consulting is an international development advisory firm specializing in climate finance, conservation finance, nature-based solutions, energy systems, and inclusive economic growth. We turn rigorous research into bankable, field-tested strategies.
What makes the firm different
Founded in 2025, QuantEco was built by economists who have designed macro-financial models inside central banks, benchmarked returns for development finance institutions, and sat across the table from community cooperatives in the field. That range is the point: we bring quantitative depth and on-the-ground realism to the same engagement.
We support governments, foundations, multilateral and development finance institutions, impact investors, and NGOs — with economic impact modeling, ROI benchmarking, market systems analysis, ESG and climate-risk modeling, monitoring & evaluation, and policy design — so that ambitious climate and conservation goals become strategies that can actually be financed and implemented.
Our mission
To advance nature-based solutions, conservation finance, and inclusive economic growth by making rigorous analysis usable, investable, and implementable.
Our standard
Every model, benchmark, and recommendation is built to withstand scrutiny from boards, investors, and government counterparts alike.
Our reach
Engagements across Latin America, Sub-Saharan Africa, the Caucasus, South and Southeast Asia, and the United States.
Three co-founders, one standard of rigor
Each trained at the Harvard Kennedy School, our co-founders lead engagements across climate finance, nature-based finance, and conservation.
