End-to-end data and research consulting for organisations across Africa and beyond. We collect, analyse, visualise, and translate data into outcomes that matter.
From field data collection to boardroom ready dashboards, we handle every step of the data journey with precision and expertise.
No questionnaire is too complex. Multi section instruments, skip logic, validation rules, offline capability, and multi language support, built precisely the way your data needs them.
We build research frameworks that hold up to scrutiny. Study design, sampling, analytical approach selection, and full methodology write-up to the highest academic and professional standards.
Rigorous quantitative and qualitative analysis that surfaces truth from complexity. From experimental datasets and programme surveys to large-scale organisational data.
Theory of Change, results frameworks, baselines, endlines, and programme evaluations built to the standards of the world's leading development funders.
Interactive dashboards, compelling data stories, and research reports that communicate insight with clarity and authority, the kind people actually read.
Value chain analysis, demand studies, market assessments, and policy research for development organisations and businesses that need evidence they can act on.
Hands-on training in data tools and methods for organisations, field teams, and researchers who want lasting in-house capability.
Find out exactly why your organisation keeps losing grants, and discover current opportunities you can realistically win. A proprietary assessment tool built exclusively for Nigerian and African NGOs, social enterprises, and development organisations.
Honestly, most data problems are not complicated. They are just unsolved. A survey sitting in a spreadsheet nobody has touched. A report due Friday with no analysis done. An M&E framework a funder keeps asking about. A multi country dataset that needs to make sense before the next donor report. A grant application that keeps losing and nobody knows why.
That is exactly where we come in. We have worked with researchers racing against dissertation deadlines and international organisations managing multi country programmes. The work looks different but the approach is the same. We take it seriously, we explain what we are doing, and we do not stop until it is right.
We catch problems early. We meet deadlines. We write reports that people actually read. And when a client's supervisor calls to say the work was exceptional, or a funder asks how the M&E framework was built so well, that is the moment that matters to us.
Data should make sense to the people who need it. That is why Diadem exists.
Diadem Data and Analytics Services works to the exact criteria that funders like the World Bank, GIZ, FCDO, and AfDB use to evaluate organisations. Those are the same criteria behind our Grant Compass tool.
We handle every step from tool design and collection through to analysis, visualisation, and reporting.
We design for the field conditions our clients actually work in: patchy connectivity, multi language teams, and funders with specific compliance demands.
A focused engagement on a single dataset, or a multi country programme evaluation. We size the approach to the problem, not the other way round.
