Our Services

Full-Stack African Language AI

Dataset Development

Custom text and speech datasets in African languages—collected, transcribed, and annotated by native speakers.

Akan (Twi, Fante), Ewe, Ga, Hausa, Yoruba, Dagbani, and more on request

RLHF for African Contexts

Preference data and reward model training from annotators who understand what 'good' looks like for African users. We evaluate outputs for cultural appropriateness, linguistic accuracy, and contextual fit.

Response ranking, cultural alignment, harm evaluation, instruction-following in local context

Model Evaluation & Red-Teaming

Native-speaker evaluation of your model's African language performance. We identify failure modes, cultural blind spots, and areas where outputs fall short of local expectations.

Detailed evaluation reports with examples, severity ratings, and recommendations

Our Advantage

Built in Africa. For African Languages.

Native Speakers, Not Translators

Our engineers speak these languages at home. They understand tone, register, proverbs, and the unspoken rules that govern communication—nuance that translation can't capture.

Ghana-Based Operations

Our core team operates from Accra, with networks across West Africa.

Cultural Context as Standard

Every annotation is informed by genuine local knowledge. We don't just check if the words are right—we check if the meaning lands.

Linguistic Range

Akan, Ewe, Ga, Hausa, Yoruba, Dagbani—and capacity to expand. If you're targeting West African languages, we can support it.
