7 years ago today we launched Slack to the world.

We started the day with a connected users record of 9.8K. Almost ten thousand humans! Using the little thing we made! We made about $5K from paid seats.

It was a good day.

They say the cells in the human body replace themselves every 7 years (this isn't true but it's poetic). It feels like that at Slack: the ongoing evolution and reinvention of the code, the company, and the product has replaced much of what we started with, though the DNA remains.

The dent we set out to make in how people spend their time at work is apparent. Slack and similar products have largely replaced email for a huge number of people. People's expectations of the quality and care that goes into work software have risen.

Also: lots of emoji. A lot.

It's a good dent, I think. The next seven years will be a chance to make sure that people and working teams – with all their diverse and complex needs (and the insane volume of custom emoji they generate) – will remain at the center of this paradigm shift.

Our mission remains to make people's working lives simpler, more pleasant, and more productive. There sure is a lot to do.

See you in 2028.
