Theory of Change Builder
A Theory of Change is a written explanation of how and why your program creates change — mapping the steps from your activities to the outcomes they produce, and naming what has to be true for each step to connect. It was pioneered by Carol Weiss in the 1990s as a tool for making beliefs explicit enough that data could confirm or challenge them.
Without a Theory of Change, your impact narrative is a story. With one, it becomes a testable framework — the foundation of every serious investor due diligence, grant application, and impact report. Investors, DFIs, and grant bodies increasingly require it as baseline.
Why you need one as an impact founder
✓Investors and grant bodies require it before due diligence
✓Aligns your team around a shared definition of success
✓Creates the metrics framework for GIIN IRIS+ and SDG reporting
✓Makes your impact claims testable — not just stated
✓Separates you from ventures with narrative-only impact claims
✓Required by most DFIs, blended finance structures, and ESG-aligned capital

Step 1 of 7
Step 1 of 7 — Context
Your venture context
Set the foundation. Everything flows from here.
Name your venture, sector, and stage. Your Theory of Change language will be tailored to your context throughout.

MVP / Traction
First users or customers
Growth / Scale
Revenue, expanding
Mature
Established operations
Step 2 of 7 — Problem
The problem you're solving
Who is affected, and why does this situation persist?
Be specific: name who is affected, the scale of the problem, and why existing solutions haven't solved it. The more precise, the stronger your ToC.

Step 3 of 7 — Inputs
Your inputs
What you commit — the resources, people, and capital that make your activities possible.
Inputs are what you invest before any activity happens: funding, staff, technology, partnerships, and expertise. Be concrete.

Step 4 of 7 — Activities & Outputs
What you do and what it produces
Activities = what you deliver. Outputs = the direct, countable products of those activities.
Activities are your core programs or services. Outputs are the tangible, measurable things they produce — units sold, people trained, systems installed. Outputs are not yet the change itself.

Step 5 of 7 — Outcomes & Impact
The change you create
Outcomes = change in stakeholders. Impact = long-term systemic change.
Outcomes are changes in people's knowledge, attitudes, behaviour, or circumstances — often short to medium term. Impact is the long-term systemic shift your work contributes to, beyond individual beneficiaries.

Step 6 of 7 — Assumptions
Your assumptions
What has to be true for each step in your pathway to connect.
Assumptions are the conditions your theory depends on. A Theory of Change becomes a real theory only when its assumptions can be tested. Name what must hold for your chain of change to work.
Assumption 1 — The need is real
Assumption 2 — Activities are delivered
Assumption 3 — Outputs are taken up
Assumption 4 — Change persists
Step 7 of 7 — Framework Alignment
SDG alignment and impact metrics
Map your impact to global frameworks. This is what investors and grant bodies require.
Select the SDGs your work contributes to, then add up to 6 specific metrics. Use GIIN IRIS+ language where possible — e.g. "Number of individuals with improved access to clean energy" rather than "people helped".

How global frameworks are built into this Theory of Change
GIIN IRIS+
Your metrics use GIIN IRIS+ language — the global standard for impact measurement used by 2,000+ impact investors. This makes your data comparable and investor-ready.
UN SDGs
Your SDG alignment maps your outcomes to the global development agenda. Most DFIs, grant bodies, and blended finance structures require SDG alignment as baseline.
Theory of Change
This framework follows the six-component ToC pathway (Center for Theory of Change, Better Evaluation, NPC) — the form most widely accepted by impact investors and grant evaluators.
Impact Management Project (IMP)
Your outcomes and assumptions map to the IMP's five dimensions of impact: What, Who, How much, Contribution, and Risk — helping you pre-empt investor due diligence questions.
ESG Alignment
Your theory of change provides the impact narrative required by ESG-aligned investors and is structured to be integrated into standard ESG reporting frameworks.
