The problem
For thousands of sellers in Nigeria, the business lives in WhatsApp. Every unread DM is a lost sale, every “last price” argument erodes margin, and the real work — stock, payment links, delivery — is scattered across apps.
Case study — 01
Live beta
BetaInbox: every DM, one inbox, zero missed sales.
An AI salesperson for WhatsApp-first sellers. It answers every customer, holds the price floor, and turns conversations into paid orders — then Boost brings in more buyers.

01 — The brief
WhatsApp is the storefront.
The approach
Put the whole sale on one screen. BetaInbox connects conversations, catalog, price floors, payments, and delivery — with an AI that answers first and only pulls the seller in when a human decision actually matters.
02 — The product
An AI that sells, not just chats.
01 / Conversations
AI that answers first.
Every customer gets a reply in seconds — a greeting, a straight answer about the product, and the seller's floor and target price in mind. Quiet buyers get a nudge before the sale goes cold.
- Answers every WhatsApp DM, day or night
- Knows the catalog, stock, sizes, and price floor
- Escalates only when a human decision matters
02 / Growth
Boost: ads into the inbox.
Done-for-you ads on the platforms sellers already use. BetaInbox creates and runs the campaign across the catalog, and interested shoppers land straight in WhatsApp — not a separate checkout.
- Facebook, Instagram, and TikTok placements
- Promotes the seller's entire catalog
- Free while the beta is open
03 / Operations
One screen for the whole sale.
Products, stock, payment links, and delivery status live beside the conversation. The AI serves the menu, quotes the right price, and the seller can step in with one tap.
- Catalog with stock, sizes, and designs
- Fixed, negotiable, or budget-first pricing
- Payment links and delivery tracking in-thread

04 — The craft
Designed for the hustle.
01
One calm surface
Cream and orange instead of enterprise grey. Conversations, products, and orders sit on a single screen so a seller can move without switching apps.
02
Guardrails, not guesswork
The AI is grounded in the seller's catalog and stated floor. It answers with their products and their limits — it does not invent a product or a discount.
03
Mobile first, installable
Built for a phone in one hand and stock in the other, then wrapped for Android with Capacitor so it runs like an app, not a bookmark.
05 — Status
Live, in public beta.
BetaInbox is running today on WhatsApp, with a responsive web app and an Android build. Core selling tools are free while the beta is open.
