African founders need fast, affordable product validation, and participants need a dignified way to earn from that work. Typical research ops are slow, expensive, and pay in cash rails that stall in emerging markets.

Problem What I built Technical notes
- A two-sided marketplace: Rez for researchers, Pax for verified participants, plus public poll insights on the marketing site.
- GoodDollar (G$) as the default reward currency, with stablecoin payouts and instant withdrawals via MiniPay / GoodWallet.
- On-chain stats, a G$→USDm quote API, and lead funnels that turn inbound research demand into booked studies.
- Adjacent products under the same umbrella — GoClaim, The Good Pax App, and Celina as the Intelligence wing.
- Marketing site on Vite + React with prerendered SEO routes for public poll pages, Firebase + Supabase for insights, and Cloudflare Workers for reserve quotes.
- Dual-Firestore architecture: Rez writes tasks into the Pax store; researchers read completions filtered by their org.
- Celo smart-contract stack for gas sponsorship, wallet registry, task management, and cryptographic reward verification.
- Born at Build with Celo 7 (2024); supported by Prezenti grants.
