Kenyan tech-worker organiser, former Samasource team lead on the OpenAI ChatGPT toxicity-classification project, and one of the most public faces of the Nairobi worker-led AI-supply-chain organising layer; co-founder, founding-committee member, and administrator of the African Content Moderators Union (ACMU) and co-founder and Chief Operating Officer since 2024 of Techworker Community Africa (TCA). His full name on the public record of the July 2023 parliamentary petition against OpenAI and Sama is Richard Mwaura Mathenge. He was named to the inaugural TIME100 AI list in September 2023 — Billy Perrigo's profile recording his age at the time as 38 — was listed among the Top 100 Kenyans of 2023, and in October 2023 was appointed to the inaugural Policy Steering Committee of Partnership on AI under his African Content Moderators Union affiliation, alongside Rumman Chowdhury, Alexandra Givens, Sam Gregory, Alondra Nelson, and Irene Solaiman.
Mathenge worked at Sama in Nairobi as a team lead on the OpenAI-contracted ChatGPT toxicity-classification project that ran from late 2021 until Sama's February 2022 termination of the contract — the outsourcing arrangement under which the Nairobi workforce read and classified textual descriptions of sexual abuse, hate speech, and violence so that OpenAI could build the safety layer that became ChatGPT. He has consistently described the work as paying less than USD 2 per hour and as having produced post-traumatic and other psychological consequences he has named publicly in the Guardian-via-Business-and-Human-Rights-Resource-Centre coverage of the petition as having "destroyed me completely". The TechPolicy.Press progress check on the union records that during his Sama tenure he advocated internally for better mental-health support for the team before his own contract was terminated, and that he has subsequently framed the petitioners' broader stake plainly: "This is a win for all content moderators, not just for me."
Mathenge's organising work runs along three connected tracks. He was one of the 150-plus African AI workers who voted at the May 2023 Nairobi summit to establish the African Content Moderators Union, one of the union's founding committee of six former employees, and serves as its administrator — sitting alongside committee secretary and primary spokesperson James Oyange and chairperson Mophat Okinyi at the head of the union's structure. He is one of the four named petitioners, alongside Mophat Ochieng Okinyi, Alex Mwaura Kairu, and Bill Kelvin Mulinya, on the July 2023 Mutemi-led parliamentary petition asking the Kenyan National Assembly to investigate Sama and the wider Big Tech outsourcing chain — counselled by Mercy Mutemi of Nzili & Sumbi Advocates and supported by Foxglove. In 2024 he co-founded Techworker Community Africa together with chairperson-and-ACMU-peer Mophat Okinyi and a four-person founding team, serving as its Chief Operating Officer — building TCA into the largest reported headcount among the worker-led bodies in the Africa Tech Workers Movement coalition, a hybrid NGO / for-profit / worker-supporting-DAO structure distinct from ACMU's trade-union shape and the Data Labellers Association's sectoral-association posture.
Across the post-2023 organising cycle Mathenge has consolidated a recognisably international public-facing posture for the worker-side of the Kenyan AI supply chain — his perspectives on the African tech sector published in The Wall Street Journal, The Guardian, and the BBC; his name carried alongside Mophat Okinyi and other ACMU-and-DLA peers among the 72 named signatories of the May 2024 Open Letter to President Biden from tech workers in Kenya timed to the US–Kenya Strategic Trade and Investment Partnership announced during President Ruto's state visit; his Partnership on AI seat the only Policy Steering Committee position held by a worker-organiser from the global-South labour layer that produces frontier-AI training data. His distinctive contribution to the make-AI-good movement is the consolidation of an organiser's identity that runs from the team-lead floor of the Sama RLHF workforce — the non-AI publics whose hand-classification of toxic content underwrites generative-AI safety — through national trade-union founding, a parliamentary petition, a hybrid worker-owned organisational vehicle, and a seat at one of the field's largest multistakeholder policy tables.
