Technical Cofounder – Mobile App Lead (Equity Role)
Equity + Leadership Role | Remote | Africa-focused
We’re building something bold — a platform designed to empower everyday people through real-world commerce and daily utility. The concept is built, the community is growing, and the brand is already in motion. Now, we’re ready to build the MVP.
We’re looking for a technical cofounder — someone with the skill to build and the vision to lead.
What You’ll Own:
• Lead the mobile app development (Android-first; iOS optional for now)
• Build core features: user registration, listings, wallet logic, escrow integration, and payments
• Collaborate on product direction and tech decisions
• Scale with the company as a core part of the founding team
Ideal Experience:
• You’ve built marketplace-style or P2P mobile apps before
• You’re comfortable with payment APIs like Paystack, Flutterwave, or others
• You understand how to work with wallets, escrow flows, and multi-user platforms
• You’re not just a builder — you want to grow with a brand and own a meaningful slice of it
Your Role Is Not Freelance.
This is a cofounder opportunity — you’ll help shape the product, tech stack, and long-term vision. You’ll receive equity and work closely with the founding team to build a scalable African-first product.
