Built from the inside.

How we collect better data than anyone else
1
Recruit — native speakers from universities, communities, and professional networks across Nigeria
2
Collect — spontaneous, natural recordings in real-world scenarios. Not scripted.
3
Review — native speaker quality check for tonal accuracy, clarity, and cultural authenticity
4
Annotate — transcription verified by a second independent reviewer with full metadata labeling
5
Pay instantly — contributors paid same-day in Naira via automated Korapay bank transfer
We are Nigerian. Our speakers are Nigerian.
No foreign company can replicate the community trust that comes from shared identity, language, and culture. Our contributors participate because they trust us — not a platform they've never heard of.
Proven payment infrastructure at scale
We operate automated Korapay payout systems across multiple Nigerian platforms — processing instant bank transfers to any Nigerian account. Contributors are paid same-day, every time, without friction.
Ethical collection is our core practice
Every contributor signs digital consent before participation. All data is fully anonymised before delivery. We comply with Nigeria Data Protection Regulation (NDPR) and applicable international privacy standards.
Pilot-first. No blind commitments.
We offer a 10-hour pilot batch before any full commission. You review quality, format, and accuracy first. Full engagement proceeds only on your satisfaction.
