Does my data stay with me?

We can work on your servers, in a dedicated encrypted environment, or on pseudonymised data. A non-disclosure agreement is signed before any work starts.

How long does a database clean-up take?

An audit usually takes one to two weeks. Cleaning depends on volume and complexity; we deliver a first corrected batch from the second week.

Data Cleaning & Preparation | Africa Data Entry

Analysts spend up to 80% of their time preparing data. We give them that time back.

Duplicate customer records, badly formatted phone numbers, village names spelled five different ways: these flaws look harmless, yet they distort every indicator computed afterwards.

We audit your datasets, measure their quality across six dimensions (accuracy, completeness, consistency, uniqueness, validity, timeliness), then fix them with documented, reproducible rules in Python, SQL or your own tools.

Above all, we put safeguards in place so errors don't come back: master data, entry controls, quality alerts.
