Evidence that moves decisions.
From what you have, to what your stakeholders need. Decision-ready evidence.
You may be here because something important you are working on is murky, messy, or unclear. And it must land.
A disclosure. A measurement framework. A case for funding. An impact claim that has to hold up.
You have a pressing deadline. A maze of frameworks. Conflicting guidance. And the room is waiting for a resolution. You may not know where to start or how to cut through it.
This is the work we do: we help you reduce needless complexity and get to clarity, soundly, in time.
Who this is for
By audience
• Ventures and projects building their impact case.
• Accelerators that are prioritizing projects across a portfolio.
• Funders and investors who are making selection and due diligence decisions.
• Leaders who are justifying investment in projects where the value is not purely financial.
By situation
• Your funder is asking for evidence of impact, but your reports are not enough.
• You need to bring investors or partners along for a catalytic or blended-capital opportunity.
• Your team is not yet aligned on what success looks like, and the project depends on getting alignment right.
• You are asked to justify the impact or ROI for something that is not financial.
Evidence in your context, structured for your decision needs.
What we build
You share the material you have. You answer some simple questions. We work from your existing materials, prioritize what matters, identify and apply the right frameworks, and turn the work into outputs your stakeholders can use.
You can expect answers you need, not a theoretical document you do not know what to do with.
We work with frameworks your stakeholders recognize, including IRIS+, OECD DAC, SDG Impact Standards, IFRS, GRI, Theory of Change, and others, carefully scoped to the depth your context needs. No decorations. No excess. Nothing you do not need.
We put the questions in the right order, so you can move quickly toward a usable answer.
You leave with something organized, grounded, and short enough to be practical in real life. And the peace of mind that comes with it.
Align
Stakeholder mapping, roles, and engagement structures so teams can agree on what matters, what to measure, and how decisions will be made.
Measure
Metrics, theories of change, and economic value models built around the choices you need to support.
Translate
Impact narratives, investment cases, and decision materials that clarify findings and support the case for action.
Practical tools, in development
Ready-to-use toolkits and templates designed to help you prepare a credible first draft — not start from a blank page. Each tool creates a pathway from raw inputs to decision-useful outputs:
Impact measurement templates.
Theory of change builders.
Value-for-money models.
Evidence memo templates.
Funder-ready reporting structures.
