We build the African datasets your models are missing — to your specification.

BSG DataWorks collects, annotates, and licenses human-sourced speech, image, video, and language data across Nigeria and West Africa. Tell us what your model needs; we recruit the speakers, run the collection, and deliver rights-cleared, consent-documented data your legal team can sign off on.

Commission a dataset Hear a sample first
Ready to evaluate Nigerian English and Yorùbá speech

Representative samples and time-aligned transcripts available for technical review.

Native-speaker QA Human review at every delivery stage

Transcriptions, annotations, and metadata checked against agreed quality criteria.

Rights-ready Consent-documented commercial data

Built with contributor records and a clear audit trail for AI training use.

What we collect

Four data types, one compliance standard.

Most of our work is commissioned: you define the specification, we build the dataset. Everything below is collected from consenting human contributors — never scraped, never AI-generated.

Services

Beyond collection.

We work with teams at every stage: those who need data built from scratch, those who already have data and need it made usable, and those who need to know whether their African data strategy will survive a compliance review.

Commissioned data collection

You specify languages, domains, demographics, devices, and volume. We recruit, obtain consent, collect, and QA — then deliver to your format.
