Evidence for impact capital

Independent evidence for impact investment decisions.

IntelliSearch serves impact investors, development finance institutions, enterprises and public bodies. We offer pre-investment evidence reviews, investment readiness and policy evidence. We link every conclusion to its source document, and a member of the IntelliSearch team reviews and signs every deliverable.

What a review shows

Each material claim, tested against its source.

Claims that hold, claims with no document behind them, and claims the documents contradict, each with a page reference.

Our purpose

Capital for social and environmental goals should be allocated on evidence that can be independently examined.

We apply four tests to any intervention. Is it additional? Does it show contribution against a stated counterfactual? Is the change measured? Can it continue when grant or concessional funding ends? We help investors, enterprises and public bodies find the answers.

Our principles

One agreed definition and one source for every measure.

  1. 1

    We work from data. Each measure has one agreed definition and one source, whether it counts revenue, carbon or farmers reached.

  2. 2

    We link every figure in our analysis to its source document.

  3. 3

    We measure social and environmental results with the same rigour as financial ones.

  4. 4

    We keep national development goals in view. The evidence that moves investment also shapes the rules.
