Modern Messaging

Fast, flexible messaging for Mac, PC, iPhone, iPad & Android. Archived and organized as you go, with configurable alerts, notifications and sync so you never miss a beat.

Any File, Anywhere

Share, serve, star & comment on files. Images, PDFs, text snippets, zips —even files you store elsewhere, like Google Docs— are all indexed & accessible wherever you go.

Universal Search

Slack is built around search from the ground up. It captures everything you put in. Slice, dice, filter, sort and winnow: you'll find what you need faster.

Slack

It's like an infinite brain for your whole team.

"We were looking for something to help with team communication, and nothing really stuck until we started using Slack. It looks good, feels right and search just works: being able to trust that I can find things again when I need them is good peace of mind."

Dustin Senos, Medium

Dustin Senos
Design and UX Lead

Medium is a new place on the Internet where people share ideas and stories that are longer than 140 characters. It's simple, beautiful, collaborative, and it helps you find the right audience for whatever you have to say.

Slack

One search box for everything.

"To create a strong emotional experience that touches our audience, it requires the whole development team to work as one voice. To make that possible it's essential to have strong communication between each team member. Therefore Slack is essential to us."

Jenova Chen, TGC

Jenova Chen
CEO

TGC (thatgamecompany) design and develop artistically crafted, broadly accessible video games like Flower, flOw, Cloud and Journey, the #1 game of 2012.

"We're most excited about Slack's emphasis on integration and search. The big problem we have with our current communication tool is all the history is local – it makes it impossible to share conversations as a team. We need to be able to reference files and get them into the search index so they're assets the whole team can work on. With Slack, that happens automatically."

Rdio is a groundbreaking digital music service reinventing the way people discover, listen to, and share music.

Slack

Make better decisions, faster.

"The biggest thing is nobody thinks about Slack – it just always works. The tool itself gets out of our way so we can get work done. Any good tool makes it so you don't think about the tool but the things you want to get done. I never think about it – that's perfect."

Cozy is a San Francisco-based startup that makes renting easy for both landlords and renters. With world-class customer service and first-of-their-kind products for rent payments, applying/screening, and personal security, Cozy is the best way for small landlords and renters to get things done.

"Team coordination was a challenge before Slack. I wasn't aware of issues until they became urgent. As a project manager, I need to keep informed. Slack has become one of my key tools – and my favorite. It's been especially amazing to use because it's the only tool our programming team has adopted that I also find essential. Slack is the tool that everyone uses because it works for all of us."
