Slack vs WhatsApp
WhatsApp started first, in 2009, 4 years before Slack.
Why Slack lasted
- It turned IRC-for-work into a company default and made search across chat a reason to stay.
- Salesforce bought it and the login did not vanish, which is the adult form of surviving.
Why WhatsApp lasted
- It is the SMS of half the planet. Network effects at that scale do not care about your new app.
- Facebook bought it and was not allowed to fully melt it into Facebook. The brand stayed the brand.
