Nairobi has become a vital hub for data annotation and labelling that powers the world’s leading AI systems, including those developed by OpenAI and Meta.
Through outsourcing partners such as Sama, thousands of Kenyan workers process huge datasets, including labelling text, images, and videos and moderating harmful content to train large language models, enhance safety filters, and improve AI accuracy globally.
This invisible yet essential labour supports the rapid advancement of generative AI while generating economic value for Kenya’s digital economy.
However, it also raises important questions about labour dynamics, working conditions, and long-term sustainability within the AI value chain.
Nairobi as a Global AI Data Hub
Kenya’s Silicon Savannah has positioned Nairobi as a preferred location for AI data work. Companies such as Sama maintain significant operations in the capital, contracting directly with major technology firms.
Workers annotate data for OpenAI’s ChatGPT safety systems (including toxicity detection) and support Meta’s content moderation pipelines, including recent efforts related to Ray-Ban AI smart glasses footage.
The scale is substantial: Sama alone employs thousands of workers across Kenya, forming a notable portion of the country’s tech workforce.
Tasks range from computer vision annotation and natural language processing to reviewing complex, sensitive material for model refinement.
Kenya’s role extends beyond U.S. firms, with emerging involvement from Chinese AI developers seeking similar cost-effective labelling capacity.
This outsourcing model allows global AI leaders to access high-volume, high-quality labelled data without building internal teams in high-cost markets.
Economic Contributions and Scale of Outsourcing
Data annotation contributes meaningfully to Kenya’s BPO (business process outsourcing) sector and broader digital economy. It creates entry-level employment opportunities for a youthful, English-speaking workforce amid high youth unemployment rates.
The activity generates foreign exchange earnings and supports local infrastructure development in tech parks such as Sameer Business Park.
While exact national figures remain opaque due to the fragmented nature of outsourcing contracts, the sector aligns with Kenya’s National AI Strategy 2025–2030, which identifies AI-related services as a driver of GDP growth, job creation, and digital inclusion.
Outsourcing volumes have grown steadily, driven by the explosive demand for training data as AI models scale.

Labour Dynamics and Calls for Improved Conditions
The labour model presents a complex picture. Workers often earn between US$1 and US$2 per hour significantly lower than equivalent roles in the United States or Europe while handling repetitive, sometimes traumatic content under strict non-disclosure agreements and algorithmic performance targets.
Recent media investigations (including reports from 2025–2026) have highlighted challenges such as psychological strain from exposure to graphic material, limited mental-health support, and concerns over contract stability.
In response, workers established the Data Labellers Association (DLA) in 2025–early 2026 to advocate for fair compensation, psychological support, transparent contracts, and an end to exploitative practices.
Legal actions and policy discussions continue, with Kenyan courts examining accountability of international clients and contractors.
These efforts reflect broader calls for ethical AI supply chains that ensure fair wages and worker protections.
Kenya’s Competitive Advantages
Kenya offers distinct advantages that sustain its position in the AI data ecosystem:
- Cost-effectiveness: Competitive labour rates combined with high-quality output enable global clients to scale efficiently.
- Digital connectivity: Robust mobile penetration (over 118% in recent estimates), expanding fibre networks, and improving broadband infrastructure support reliable, high-volume data work.
- Talent pool: A young, tech-literate, English-speaking workforce with growing digital skills, reinforced by initiatives in the Silicon Savannah.
These factors, alongside stable governance and a supportive policy environment, make Kenya an attractive partner for AI training pipelines.
Pathways Toward Higher-Value Roles in the AI Value Chain
Kenya is actively transitioning from low-value annotation tasks toward higher-skill contributions.
The National AI Strategy 2025–2030 prioritises talent development, including AI literacy, curriculum integration, and reskilling programmes.
Initiatives such as Moringa School’s AI upskilling efforts (targeting thousands of youth with practical machine-learning competencies) and partnerships with global tech providers aim to equip workers for roles in model development, ethical AI governance, and local AI solution design.
These programmes seek to move Kenyan talent upstream in the value chain from data labelling to innovation and oversight ensuring more sustainable economic benefits.
Looking Ahead
Kenya powers critical segments of the global AI training pipeline through Nairobi’s skilled workforce and cost-effective, digitally connected infrastructure.
While economic contributions and scale are significant, labour dynamics underscore the need for fair compensation, improved working conditions, and ethical practices.
Through worker advocacy, policy frameworks, and targeted upskilling, Kenya is positioning itself not merely as a data supplier but as an active participant in higher-value AI development.
