Build
AI for digital trade, payments, logistics, manufacturing and services that create jobs.

For youth-led startups from across West Africa already using AI to build businesses, widen clean energy and help farmers grow more. Submit online, pitch at Bintumani, and meet the winners at WAIIS 2026 in Freetown.
About the challenge
Young Africans are already building AI products that power new businesses, widen clean energy access and help farmers grow more. They rarely reach the rooms where investment and policy decisions are made.
WAIIS 2026 brings ministers, financiers and development partners to Sierra Leone from 13 to 19 November. This challenge gives youth-led startups from across West Africa a place in that week on their own terms.
Founders from different member states compete on the same terms, pitch in the same room in Freetown and meet the same investors, building the cross-border links regional integration depends on. Solutions that can scale beyond one country are rewarded through the impact criterion.
Who can enter
This is not an ideas competition.
The lead founder is aged 18 to 35.
With a solution that can serve Sierra Leone and the wider region.
If shortlisted.
The three themes
Each theme names one winner, who receives USD 5,000. Awards are paid within 30 days of the announcement, once identity, age and bank details are verified.

AI for digital trade, payments, logistics, manufacturing and services that create jobs.

AI for clean and off-grid energy, energy efficiency, climate risk and environmental monitoring.

AI for crop advice, pest and disease detection, market prices, agro-processing and climate risk.
Build week





Independent judging
Every eligible entry is scored online by both judges of its theme against five criteria. The top three in each theme then pitch live at Bintumani.
How many people across West Africa the product can reach, how much it changes for them, and whether it can scale across borders.
Whether AI is central to the product and works as shown in the demo and the live pitch.
Users, pilots, revenue or partners, and a credible path to sustain the business.
Data protection, fairness, and reach to women, rural users and low-connectivity settings.
Capacity of the team to deliver and grow.
Screening. AfCEN checks every entry for eligibility.
Desk scoring. Both theme judges score each eligible entry. The chair moderates any gap of more than 15 points.
Shortlist. The top three in each theme get a pitch slot at Bintumani on 14 November.
Live pitch. Judges score each pitch on the same criteria. The final score is 40% desk score and 60% live pitch.
Deliberation. Judges agree the winner in each theme in a closed session on 14 November.
Sealed results. Results stay sealed until the announcement on 15 November. Every shortlisted founder is invited.
Invited investors join the questions on pitch day and may book follow-up meetings with any shortlisted startup. Only the judges score.

Photos and closeAfCEN
Mixed tables of six to eight (founders from different countries, hub managers, investors and officials) each draw a barrier card: capital, data and compute, rules and regulation, markets and public buyers, or power and connectivity. In 10 minutes a table maps who the barrier hits and why it persists; in 25 it designs a workaround on a one-page canvas; then it pitches in 90 seconds and the room votes by QR code. The canvases become a Youth Innovation Workaround Playbook, shared after the Summit with every participant, partner and ECOWAS ministry.
