About us

We're building the commerce layer for African WhatsApp.

WA-B started in Osu with one kelewele stand that was losing orders to unread messages. Today it runs checkout, payments and delivery for shops from Madina to Takoradi — on the number their customers already use.

The story.

WA-B started in 2024 in a kebab shop in Osu. The owner, Auntie Ama, was juggling 18 orders on three phones. Her best customer had just bounced because she missed his message during the lunch rush. We built the first version of WA-B that weekend: a single Python script that took her order, charged MoMo, and printed a receipt.

A year later we'd outgrown the script. The platform now runs hundreds of merchants across Accra, Kumasi and Takoradi. Auntie Ama is customer #1 and still on the Kiosk plan.

We're a small team: six engineers, a designer, two operations leads. We're not VC-funded. We're profitable, and we plan to stay that way.

What we believe.

Meet sellers where they are.

No app to teach. The chat they already answer becomes the shop.

Cash is a first-class citizen.

MoMo and cash-on-delivery are not edge cases here; they're the default.

Show the math.

Fees, payouts and estimates are printed in full, never buried.

Build for bad networks.

Offline queues, durable webhooks, retries. Orders don't get lost.

The team.
