Two billion people use it. End-to-end encrypted, voice, video, groups. The default messaging app outside the US.
Our Take
The messaging app that swallowed the world. Two billion users means your customers, team, and mum are already on it. End-to-end encrypted, dead simple, and the Business API is genuinely useful for founder-to-customer comms. It's not fancy, but it's where conversations actually happen.
What we like
- Two billion users — your audience is already here, no onboarding needed
- End-to-end encryption on all messages, calls, and media by default
- WhatsApp Business API lets you automate order updates, support, and broadcasts
- Voice and video calls are rock-solid even on patchy connections
Where it falls short
- Meta owns it — if you care about data privacy beyond encryption, that's a tension
- Group chats max at 1,024 people and get chaotic fast with no threading
- Desktop app is a second-class citizen compared to Telegram or Slack
Verdict
If your customers or team are on WhatsApp (and statistically, they are), just use it. The Business tools are surprisingly capable for support and broadcasts. Not a Slack replacement for internal work, but unbeatable for reaching real humans.
