A day in the life

Nine hours a day,
online.

South Africans spend more time online than anyone else on Earth. And nearly all of it happens inside a handful of apps on one screen.

Where business gets done

Place. Page. Conversation.

🏬
First

The storefront

For centuries, business was done in person. Location, signage, the handshake across the counter.

🌐
Then

The website & socials

Everyone went online. Your site, Instagram, YouTube. Great for being found, but mostly one way.

💬
Now

The conversation

WhatsApp is where the relationship lives. Two way, and the one place you can own and control it.

Where it's going

Messaging a business
is exploding.

175M / day today so far where it's heading ↗

More than 175 million people already message a business on WhatsApp every day. And that's just where the curve is now.

Daily conversations with businesses on WhatsApp. Solid line to today (175M+, Meta's reported figure); dashed line is the trajectory.

A quick plot twist

But there's more than
one WhatsApp.

Everything so far has been the one you know. The most common one. There are actually three.

Tip 1 of 6

Keep business and
personal apart.

Run both apps on one phone, two numbers. Many phones now hold a second number just for work, so customers never land in your personal chats, and 50 unread business messages never get buried under memes from friends.

Labels and notes
are your memory.

Label every chat by where it sits in your sales cycle, and keep a note for context. So when someone messages two years later, you know exactly who they are and what they wanted.

Landing page
Anonymous visitor. Bounces. You never know who.

Tip 3 of 6

Click-to-WhatsApp ads
are underrated.

Most ads send people to a landing page where they stay anonymous and bounce. An ad that opens a chat hands you a real, named lead you're already talking to. The most underused tool in the app.

"Your order is ready for pickup"
"The item you asked about is back"
"20% off everything!" to everyone
Any unofficial bulk-send tool
Tip 4 of 6

Earn the right
to broadcast.

Customers hate messages that don't concern them. Keep broadcasts high-intent and relevant to keep their trust. And only broadcast with the app's own tools: anything else risks a ban.

Adding people to groups you've never messaged
Modded apps or unofficial automation
Bulk-messaging people who never opted in
Tip 5 of 6
5

Don't get
yourself banned.

Adding people to groups you've never messaged gets you flagged and locked out fast. And never use anything that isn't official Meta software. Stay on the official rails and you stay safe.

Be one tap from
a Google search.

Google lets you put your WhatsApp number on your business profile, so searchers message you straight away instead of hunting through a website. People prefer messaging, and most businesses still haven't added it.

WhatsApp, number three

The third one
has no app.

Nothing to download, no icon to recognise. This is the WhatsApp Business Platform, the API: the engine serious businesses run on.

No app, no screen?

An API is just plumbing.

No interface of its own. It is the pipe that carries messages between WhatsApp and your software.

Launch to millions.

Paige turns a plain-language description into a working WhatsApp app. No code to write, no servers to wrangle. Describe what you want, and it goes live to the three billion people already there.

Why build here?

The case for
the conversation.

😮‍💨

App fatigue

Nobody wants another download, signup and login. Most apps are deleted within a month.

🛡️

Instant trust

Meta's red tape is hard to pass, so being on WhatsApp signals you're legitimate. And it's end-to-end encrypted.

🏠

Already a habit

You meet customers inside an app they open all day, instead of fighting for a new one.

⚡

Cheaper & faster

No app store, no download, no new interface. Push a change instantly, at a fraction of the cost.

Tin hat on. A prediction.

WhatsApp becomes
the super-app.

One place where everything gets done. It's already happening. No one has named it yet.

this with Paige.

My prompt to Paige

Build a WhatsApp Flow to survey my audience after a talk. Ten questions, feedback-focused, mostly taps. 1. Overall, how useful was this for your business? (1 to 5 stars) 2. What stuck with you most? (multi-select: the scale of WhatsApp, the three WhatsApps, the maturity tiers, what it costs, Paige, the super-app future) 3. Did it change how you think about WhatsApp for your business? (Completely / A bit / Not really) 4. How likely are you to do something in the next 6 months? (Already on it / Very likely / Maybe / Not yet) 5. What's one thing you'd love to build on WhatsApp? …

Ten questions. Built, tested and deployed in 20 minutes.

Thank you

Meet customers where
they already are.

Three billion conversations are already happening. Let's build where yours live.
