Turning Africa's Data Into Lasting Impact
D4Act is an African-led consulting firm headquartered in Lomé, Togo. We specialise in impact evaluation, monitoring-evaluation-learning (MEL) system strengthening, and data & AI solutions across Africa's most critical development sectors.
Evidence-Driven Solutions for Africa's Development
Founded in Lomé, Togo, D4Act - Data For Action - was born from a simple conviction: Africa's development challenges demand African-led, evidence-based solutions. Our team of researchers, data scientists and policy experts is set up to support interventions across the continent, bridging the gap between data collection and actionable policy change.
Our vision is a future where African decision-making is consistently informed by rigorous evidence - moving beyond anecdote to data-driven governance across every sector.
Read Our Full StoryComprehensive Evidence & Data Services
We go beyond activity tracking to measure outcomes, return on investment, and long-term sustainability - delivering rigorous analysis that drives real policy change across the continent.
Impact Evaluation
Rigorous randomized controlled trials, quasi-experimental designs, and mixed-methods evaluations that reveal what truly works - and what doesn't - in development programming.
📊 RCTs · Diff-in-Diff · PSMMEL System Strengthening
Building robust Monitoring, Evaluation, and Learning frameworks that transform scattered data into coherent learning systems - from theory of change design to real-time dashboards.
📈 Dashboards · ToC · KPIsData & AI Solutions
Leveraging machine learning, geospatial analysis, and AI-powered tools to unlock patterns in large-scale African datasets - from satellite imagery to health information systems.
🤖 ML · GIS · NLPWhere We Create Impact
Our work spans four critical development sectors across Africa, each requiring deep contextual expertise and locally-led approaches to measurement and learning.
Health Systems
Enhancing governance, service delivery, and accountability in health programs - from maternal health to disease surveillance.
Education & Skills
Measuring learning outcomes, teacher effectiveness, and education policy impact across primary, secondary, and vocational systems.
Agriculture & Food
Supporting smallholder farmers and value chains with data on productivity, market access, and climate resilience across Sub-Saharan Africa.
Livelihoods & Jobs
Evaluating youth employment, vocational training, entrepreneurship programs, and social protection systems for sustainable livelihoods.
Training & Capacity Building
Professional development programmes in impact evaluation, data science, MEL systems, and evidence-based policy for African development practitioners.
Working With Leading INGOs & Donors
From multilateral funders to grassroots networks, we deliver evidence that decision-makers act on.
Evidence That Moved a Decision
Sectors and signals where rigorous evidence is reshaping funding and operating decisions across African development.
Sub-Saharan Africa carries 58% of the world's under-five deaths
The 2025 UN IGME Child Mortality Report finds 4.9 million children worldwide died before age five in 2024, with sub-Saharan Africa accounting for 58% of those deaths and infectious diseases driving 54% of them. Progress has slowed sharply. D4Act builds the MEL systems that distinguish health programmes that move mortality from those that simply add headcount - the distinction donors need before approving the next funding cycle.
Only 11% of children read at grade level by age 10
The World Bank's 2025 AIM4Learning programme launch reported that across Eastern and Southern Africa, only 11% of children can read and understand a simple text by age 10. The Bank is mobilising $1.54 billion to address the foundational learning crisis - and donors increasingly demand evidence on which curriculum reforms actually shift learning outcomes. D4Act builds the evaluation frameworks that separate signal from spend.
A $1,000 cash transfer cut infant mortality nearly in half
A 2025 study tracking 100,000 births in rural Kenya found that a one-time $1,000 unconditional cash transfer to poor families cut infant mortality by 48% in the years families received it. With every $1 of cash transferred generating $1.50 to $2.50 of local economic activity, the case for cash sits on one of development's largest evidence bases. D4Act builds the data systems that let donors measure how those gains generalise across African contexts - and where they do not.
AI moves from curiosity to deployment in Africa
McKinsey's 2025 State of AI in Africa survey finds more than 40% of African organisations are now experimenting with or deploying generative AI. The continental AI market is projected to grow at roughly 28% per year and could add up to $2.9 trillion to African GDP by 2030. D4Act integrates AI-assisted workflows into MEL pipelines: faster qualitative synthesis, smarter data harmonisation, and pattern detection across multi-partner reporting.
Africa's payment rails moved $2 trillion in 2024
AfricaNenda's SIIPS 2025 report (with the World Bank and UNECA) shows Africa's instant payment systems collectively processed 64 billion transactions worth nearly $2 trillion in 2024 - the practical foundation of Digital Public Infrastructure on the continent. India's Aadhaar precedent suggests well-built DPI can return roughly $42 billion in reduced fraud and leakage on a $1.5 billion build cost. D4Act builds the MEL and audit layer that turns DPI spend into measurable public value.
Poor data quality costs organisations $12.9M a year
Gartner's cross-industry research puts the annual cost of poor data quality at $12.9 million per organisation, while MIT Sloan estimates that 15-25% of revenue is lost to data inefficiencies. In development programmes, the same dynamic shows up as wasted donor spend, missed indicator targets and audits that erode credibility. D4Act's data quality engine (DataPulse) and reconciliation platform (Data Bridge) are designed precisely for that leak.
