What it is

Bernard Chiira, who grew up with scoliosis, founded AT4D (Assistive Technologies for Disability Trust) in 2023 as a Kenyan-based not-for-profit and organization of persons with disabilities (OPD) to run Africa's first assistive technology accelerator. Before founding AT4D, Chiira led the Innovate Now accelerator since its launch in 2019.¹² His career spans startup ecosystem development, entrepreneurship training, and venture capital. He has written on science and disability innovation for SciDev.Net, served on the drafting committee for Kenya's ICT Accessibility Standard, and sits on the Government of Kenya's Disability Inter-agency Committee.³⁴

The accelerator has delivered 10 cohorts, supporting over 90 ventures led by more than 100 entrepreneurs across 11 countries in Africa, the UK, and the US.⁵ The free program combines mentorship, workshops, guest lectures, and hands-on disability expertise to help startups reach product-market fit.⁵ Disabled mentors with startup experience drive this approach, embedding disability knowledge directly into each venture's problem-solving process.⁶ In ENABLE terms, that mentorship, convening, and expert support are acts of resource provisioning before they become design or development.

AT4D operates three programs: the Innovate Now accelerator, the Momentous Pilot Fund (a $500,000 early-stage investment fund launched in March 2026 with the Judith Neilson Foundation), and a community network connecting innovators, funders, and policymakers.⁶⁷ Chiira describes the Momentous Fund as "the first fund on the continent dedicated to investing in emerging assistive technology start-ups," and targets up to five ventures with investment, technical assistance, and strategic partnerships.⁷ The fund makes AT4D's resource provisioning role explicit: it does not just advise founders, it supplies capital and support they can build with.

AT4D works within a broader ecosystem. The Global Disability Innovation Hub (GDI Hub), based at University College London, coordinates the AT2030 programme, a UK Foreign, Commonwealth & Development Office (FCDO)-funded initiative to improve assistive technology access globally. GDI Hub originally established the Innovate Now accelerator with Kilimanjaro Blind Trust Africa and AT4D implementing the program, funded by NORAD.⁸⁹

Nearly 200 million people in Africa require at least one assistive product, yet only 1 in 10 can access what they need.⁷ Chiira frames the challenge in terms of three interconnected barriers: accessibility, equity, and affordability.² He argues that "regulation must meet the needs of innovation" to deliver technology effectively. Current regulatory frameworks in many African countries hinder rather than help AT distribution.²

Why it matters

AT4D operates as a builder-side intervention, creating the infrastructure for assistive technology in a region where that infrastructure largely does not exist. This infrastructure gap has roots in colonial policy choices. Missionary organizations opened Thika School for the Blind in Kenya in 1944, while the colonial government withheld comparable investment in disability education for African populations.¹⁰ This pattern extended beyond education to health and technology infrastructure.¹¹ When nations emerging from colonial rule inherited public health systems, those systems contained no assistive technology supply chains, no regulatory frameworks for device approval, and no training programs for AT service providers. The Global Disability Innovation Hub's analysis of six Sub-Saharan African countries found that "by 2020, no African countries had developed National Assistive Products Lists," the foundational policy tools that direct government procurement and health system integration.¹¹ More than two decades after Kenya ratified the UN Convention on the Rights of Persons with Disabilities (2008), the WHO estimates that nearly 200 million Africans require assistive products and only 1 in 10 can access them.⁷ Postcolonial states never built the infrastructure colonialism refused to establish. International donors establish AT programs then withdraw them when funding ends, cycling disabled people through access and deprivation.

Stigma operates as an institutional mechanism shaping who can access AT. A qualitative study of Kenyans with disabilities, conducted as part of AT2030's Ghana, Kenya, and Nigeria implementation work, found that disabled people avoid using visible assistive devices despite health consequences. One respondent reported: "She needs to use a calliper... [she] hasn't used it for 5 years due to pity people have... I know it's having an adverse effect on her health." Another described a friend with a prosthetic leg who "avoids walking into the busy Nairobi streets, people stare at her, maybe laugh when they see her use her leg... Many a times [she] avoids... walking out. She keeps to herself, if [there is] something she needs, she'd rather send somebody than go for it herself."¹² The disabled people in these accounts face a structured choice: public visibility triggers stigma from strangers, while private isolation forces them to ask for human help from family members or stay immobilized. Professional norms reinforce this arrangement. Health systems across Sub-Saharan Africa offer no unified training in AT service provision, so disabled people seeking a wheelchair fitting, prosthetic leg, or hearing aid evaluate providers by individual reputation rather than by standardized credentials or outcomes. Without formalized AT service infrastructure, disabled people depend on whatever programs international donors establish and withdraw, tying AT access to charity rather than entitlement.

AT4D's accelerator is funded by international development partners: the UK Foreign, Commonwealth & Development Office (FCDO), NORAD (Norwegian development agency), and the Judith Neilson Foundation. These funders shape the program's priorities alongside disabled users' needs. Bernard Chiira positions assistive technology as "a viable entrepreneurial sector rather than purely charitable work."² Chiira's framing attracts investment capital from foundations and governments whose theories of change emphasize market mechanisms and venture growth. When investment logic aligns with disability needs, this works well. When it does not, the funder's theory of change prevails. AT4D does not control this tension. Across all builder-side market-building interventions, the pressure to demonstrate returns-on-investment and scale shifts what gets built toward products that have clear revenue models, that appeal to investors comfortable with tech startups, and that can be measured in growth metrics. Mobility devices built by Lincell from salvaged parts have lower VC appeal than AI-powered sign language translation. Both solve problems. The funding ecosystem amplifies one. Over time, the organizational ecosystem reflects funder preference. Harry Ochieng, AT4D's investment manager, frames the challenge directly: "Many investors still associate disability innovations with charity and donations. The Momentous Fund is an opportunity to change that narrative and demonstrate that this sector presents real opportunities for investment, impact, and sustainable returns."⁷ Investors, not disabled people's needs, structure the political economy of disability innovation in Africa. That makes AT4D's role in resource provisioning central, not incidental: the accelerator, the fund, and the partner network decide which ventures receive time, capital, and technical help in the first place. Chiira also operates at requirement-setting, serving on the drafting committee for Kenya's ICT Accessibility Standard and the Government of Kenya's Disability Inter-agency Committee.⁴ Innovate Now's board includes Senator Isaac Mwaura, a disabled lawmaker.⁹ Chiira's requirement-setting role and Mwaura's board position give AT4D influence over whether Kenya's AT infrastructure becomes policy obligation or remains funder-dependent.

The Union of the Physically Impaired Against Segregation published "Fundamental Principles of Disability" in 1976, drawing a distinction between impairment, what a body does or does not do, and disability, the restriction imposed by a social organisation that excludes people with impairments from full participation.¹³ This distinction does the central analytical work in AT4D's approach: Bernard Chiira's accelerator targets the infrastructure that withholds wheelchairs built for unpaved roads, sign language technology tuned to Kenyan signers, and hearing aid batteries sized for African contexts. Each absence is a restriction the social organisation imposes, not an attribute of the impaired body. James Charlton formalized the governance principle that follows from this distinction in Nothing About Us Without Us (1998), drawing explicitly on South African disability activists Michael Masutha and William Rowland of Disabled People South Africa, who had made disabled-people's leadership the operational premise of their own organizing.¹⁴ Charlton's core argument, that no policy about disabled people should be decided without disabled people's full participation, had reached him through African disability organizing before entering the global disability studies literature. In Kenya, the United Disabled Persons of Kenya, founded in 1989 as an umbrella coalition of disabled people's organizations, institutionalized that claim at the national level, establishing the organizing tradition AT4D builds on.¹⁵ Signvrse founder Elly Savatia built sign language translation with Kenyan signers as knowledge-makers because their embodied language expertise is information no engineer without that experience possesses. Lincell founder Lincoln Wamae built wheelchairs for unpaved African terrain using salvaged parts because his own movement revealed what international wheelchair designs omit. Deaftronics founders developed hearing aid batteries for African contexts because Western device assumptions did not fit African use conditions.

Disability deprivation embeds itself in disabled Africans' bodies. Disabled Africans without access to assistive technology carry an adaptation tax in their bodies. Stigma creates stress. Stress creates avoidance. Avoidance creates immobility. Immobility creates musculoskeletal complications, weakening, chronic pain, reduced cardiovascular fitness. A 2024 network analysis showed that disabled Kenyans with AT concentrated heavily in Nairobi (nearly half of all AT users in the country) despite Nairobi having the lowest disability prevalence. Resource geography alone shaped which disabled people could access technology and which could not.¹⁶ Disabled Africans without AT access either improvise compensations or endure. Stigma that keeps disabled Kenyans off visible assistive devices acts as more than psychological distress. The social arrangements that enforce stigma become embedded in stressed bodies, immobilized joints, and compressed life expectancy.

AT4D operates at the resource-provisioning, design, and development stages. Whether disabled Africans can access those ventures depends on distribution networks, manufacturing capacity, regulatory integration, and health system adoption that AT4D does not operate. A 2024 network analysis found that "innovation training organizations are not yet well integrated into the network."¹⁶ Kenya's Persons with Disabilities Act (2025) mandates accessibility standards and AT support.¹⁷ OPDs drove this recognition through county-level advocacy. Yet policy does not guarantee implementation. One OPD leader, Caroline Agwanda, stated: "Budget allocation to the county government is not just important it's the heartbeat of implementation. If counties don't get the resources, the law remains words on paper."¹⁷ Kenya's 47 counties received devolved responsibilities without the budget allocations needed to operationalize disability rights. Structural barriers separate innovation from distribution. AT4D's $500,000 fund addresses early-stage ventures but represents 0.025% of the gap the WHO estimates in Africa.⁷ Where implementation falters, disabled Africans return to navigator-side compensations: traveling to distant cities, paying out-of-pocket, abandoning unaffordable technology, or enduring without it.¹⁸

Real-world examples

In the news

Kenya Nonprofit Launches $500,000 Fund for Assistive Tech Startups (March 2026)
-- John Adoyi, TechCabal

• AT4D and the Judith Neilson Foundation launched the Momentous Pilot Fund, a $500,000 initiative to support early-stage assistive technology startups across Africa. Bernard Chiira described it as "the first fund on the continent dedicated to investing in emerging assistive technology start-ups." The fund supports digital solutions for mobility, communication, inclusive education, independent living, and digital accessibility. Coverage framed AT as a viable investment sector, not charity.⁷

Innovate Now Announces KES 2M Prize for First Winner
-- Global Disability Innovation Hub

• Lincell Technology, founded by Lincoln Wamae, won the first Innovate Now accelerator prize: USD $20,000 and three months of dedicated support. Lincell developed electric wheelchairs for African terrain that are also suitable for indoor use. Lincell had sold over a dozen units in Kenya before the prize. The first cohort included five finalists who completed a six-month acceleration program.⁹

• Signvrse started with $10,000 each from UNICEF and the We Are Family Foundation, participated in Innovate Now, and subsequently won a Presidential Innovation Award, joined the Google.org Accelerator on Generative AI, won $25,000 at Microsoft's Imagine Cup, and earned founder Elly Savatia a Mandela Washington Fellowship.¹⁹²⁰
• In June 2025, AT4D co-hosted "Accelerating Impact: Shaping the Next Wave of Assistive Technology Innovation in Africa" in Nairobi with GDI Hub, Kilimanjaro Blind Trust Africa, and Senses Hub. The event gathered AT innovators from Kenya, South Africa, Ghana, Nigeria, and Tanzania, and discussed Kenya's Persons with Disabilities Act (2025).⁸
• AT4D and its founder Bernard Chiira were recognized on the Forbes Accessibility 100 for 2025, alongside Koalaa, another AT2030-supported venture.²¹
• Kenya's Persons with Disabilities Act (2025) replaced the 2003 legislation with a rights-based framework that mandates accessibility standards and 5% disability representation in public service. OPDs led the advocacy.²²
• The Innovate Now accelerator has delivered 10 cohorts across 11 countries since 2019. The program is free and funded by international development partners.⁵

What care sounds like (builder-side interventions)

Care at the resource-provisioning, design, and development stages involves building the infrastructure for assistive technology where it does not yet exist:

• "We build technologies and communities that enable persons with disabilities to thrive." -- AT4D mission statement⁶
• "Africa is now building many new cities in Kenya. We are hoping that the technologies we are nurturing will power these future cities." -- Bernard Chiira²¹
• "Early-stage assistive technology innovators across Africa face significant structural barriers to accessing capital." -- Bernard Chiira⁷
• "All the projects had a strong user-centred approach to their product development." -- Innovate Now judges on the first cohort⁹
• "Many investors still associate disability innovations with charity." -- Harry Ochieng, AT4D Investment Manager⁷
• "Regulation must meet the needs of innovation." -- Bernard Chiira, on AT policy in Africa²

What neglect sounds like (builder-side interventions)

Neglect involves failing to build the systems that would make assistive technology available to the people who need it:

• "Assistive technology is a charity problem, not a business opportunity." *1
• "The market is too small to justify investment." *2
• "We will address accessibility after we solve the more urgent infrastructure needs." *3

*1: When AT is framed as charity, it does not attract the capital, talent, or supply chains needed to reach 200 million people.
*2: Nearly 200 million people in Africa need assistive products. The market exists. The infrastructure to serve it does not.
*3: Accessible infrastructure is infrastructure. Deferring it means building cities, transit systems, and digital platforms that exclude disabled people from the start.

What compensation sounds like (navigator-side compensations)

When the assistive technology ecosystem fails to deliver, disabled people in Africa carry this compensatory labor:

• "I modify my own wheelchair because no supplier stocks parts that work on unpaved roads."
• "I cannot attend school because the assistive device I need costs more than my family earns in a year."
• "I travel to the capital for a prosthetic fitting because there is no service in my district."
• "I rely on family members to carry me because there is no mobility device available."
• "I built my own screen reader workaround because the commercial ones do not support my language."

---

All observations occur within the context of assistive technology innovation and access in sub-Saharan Africa, where the WHO estimates that nearly 200 million people require at least one assistive product and only 1 in 10 can access what they need. A Kenyan OPD led by a disabled founder is attempting to build the builder-side infrastructure that the global AT supply chain has not delivered.
