One Ocean

An online marketplace for Nigeria where anyone can buy and verified sellers can sell, from phones to cooked meals.

Why it exists: Buying online in Nigeria often means paying a stranger and hoping. One Ocean holds the money safely until the buyer confirms delivery.

01Overview

Overview

One Ocean is one place to buy and sell almost anything in Nigeria. Buyers' money is held until they confirm their order arrived, so both sides can trust the deal. An AI helper turns a few details into a full product listing for sellers.

03Key decisions

Key decisions

  • Money is held until delivery. The seller is paid only after the buyer confirms.
  • No private chat between buyers and sellers. This stops people taking deals off the site, where scams happen.
  • Listings are checked before they go live. Banned items are blocked, and borderline ones wait for my review.
