When measurement is credible, every fund deployed reaches the right place, and every government knows whether its policies are working. Sigma IMS makes both possible through one unified methodology.
National evaluation systems and impact investing share the same goal, evidence-based decisions that improve lives. But they have developed in isolation.
Impact investors and government evaluators measure the same things, what changed, for whom, how much, who contributed, and what could go wrong, but they use different tools, different languages, and different reporting standards.
We bridge this gap. By consolidating 57 frameworks into one methodology, we enable organisations to collect data once and report to any stakeholder, while connecting national evaluation infrastructure to impact capital allocation.
This link now sits between two systems: the global framework countries use to track progress toward the Sustainable Development Goals, and the national financing frameworks, brought to the fore at the 2025 Financing for Development conference in Sevilla, that steer all finance, public and private, toward those goals. A country's evaluation capacity is where the two meet, and it is what we measure.
See How It WorksWe build operational measurement systems grounded in 57 consolidated frameworks. Your tools, your data, your independence.
Every engagement produces implementable tools in formats you already work with.
No conflict of interest. We build audit-ready systems; independent verifiers validate them.
Platform-agnostic solutions delivered in standard file formats. No vendor lock-in.
Our goal is your independence. Your measurement system works without us.
Whether you manage a fund portfolio, lead a national evaluation programme, or run a social enterprise, the underlying measurement principles are universal.
Board-ready impact systems in formats your team already uses. Structured outputs that integrate into existing reporting workflows.
