WhatsApp Usage by “Industry” (Simple View)

WhatsApp Usage by “Industry” (Simple View)

There is no clean official table of WhatsApp users by industry, but we can think about it in a simple, realistic way.

There are two different things:

  • Industries of the users (how people use WhatsApp in daily life)
  • Industries of the companies using WhatsApp Business

1. WhatsApp in Daily Life (Users by “Life Context”)

For normal people, WhatsApp is mostly used for:

  • Family & friends – the biggest “sector”, but not a formal industry
  • Work / colleagues – informal company chats, shift groups, teams
  • Community – churches, mosques, associations, clubs, school parents, groups

If we imagine 100 people using WhatsApp, a simple mental split could be:

  • 70 / 100 → mainly for family & friends
  • 20 / 100 → a lot for work / business
  • 10 / 100 → a lot for community / projects / groups

The same person can be in all three at the same time.

2. WhatsApp Business (Companies by Industry)

For companies that use WhatsApp Business, the main industries are:

Retail & E-commerce

  • Order updates
  • Delivery tracking
  • Product questions and simple support

Travel & Hospitality

  • Hotel confirmations
  • Flight / train updates
  • Customer service chat

Banking & Fintech

  • Notifications and alerts
  • Simple support and questions

Healthcare

  • Appointment reminders
  • Simple follow-up messages

Education

  • School announcements
  • Course / class groups
  • Tutoring or support messages

Local Services

  • Beauty salons
  • Restaurants and delivery
  • Taxis, transport, maintenance

Public Services & NGOs

  • Information hotlines
  • Campaigns and social projects

If we imagine 100 companies actively using WhatsApp Business, a conceptual split could be:

  • 30 / 100 – Retail, e-commerce, food
  • 20 / 100 – Local services & small businesses
  • 15 / 100 – Travel & hospitality
  • 10 / 100 – Banking / fintech / financial services
  • 10 / 100 – Healthcare
  • 10 / 100 – Education & training
  • 5 / 100 – NGOs / public services / other

These numbers are not official statistics. They are a simple way to picture where WhatsApp Business is most used.

3. How This Can Help Design New Apps

WhatsApp shows that messaging becomes real business infrastructure in:

  • Retail + local services + travel – for orders, bookings, and support
  • Healthcare + education + NGOs – for reminders and simple follow-up

For a sanctuary or healing project, a WhatsApp-style flow can be used for:

  • Simple check-ins
  • Reminders for sessions, playlists, prayers, reflections
  • Short supportive messages (not heavy medical records)

4. Which Technologies Allow WhatsApp to Offer Its Service

WhatsApp works because of five core technologies working together:

1) Internet (Data Networks)

  • WiFi
  • 3G, 4G, 5G mobile data
  • The internet replaces SMS and phone minutes

2) Smartphones (iOS and Android Apps)

  • Android app
  • iPhone (iOS) app
  • Web / Desktop app that connects to your phone
  • The phone number is the identity of the user

3) Servers (Cloud Infrastructure)

  • Deliver messages between users
  • Sync contacts and chats
  • Handle user login and account management
  • Store backups and routing information

4) End-to-End Encryption (Security Technology)

  • Uses strong cryptography so only sender and receiver can read messages
  • Protects text messages, voice calls, video calls
  • Even WhatsApp cannot read the content of the messages

5) Push Notification Services

  • Apple Push Notification Service (APNS) for iPhone
  • Google Firebase Cloud Messaging (FCM) for Android
  • These services wake up the app when a new message arrives

Simple Summary of the Technology

  • Internet – moves the messages
  • Smartphone apps – where users send and read messages
  • Cloud servers – deliver and manage messages and accounts
  • Encryption – keeps conversations private
  • Push notifications – alert users instantly when a new message comes
