Where Work Happens
(in the UK, too).

For businesses across Britain, Slack is the place where planning projects, getting answers, sharing files, getting final sign off… basically; where whatever needs to happen to make work run smoothly, happens.

Space for every conversation

Organise your team’s communication in open channels, for a transparent view of all that’s going on, or in private channels that hold only select members. Or, for highly-focused discussions, you can use direct messages to talk one-on-one or in small groups.

Face to face, wherever you are

When typing isn't cutting the mustard, take your conversation from finger-to-keyboard to face-to-face with a voice or video call. Use Slack’s own one-to-one or group calls — or use one of the many services that seamlessly integrate with us — and start a call with a single click.

Focus and flow

Share files, keep notes, and, most importantly, connect all the tools you use with Slack to avoid the faff of constantly switching between windows. From support tickets and code check-ins, to error logs or sales leads, you can gather, share, and respond to them directly within Slack.

Searchable and scientific

Everything in Slack — from conversations to files to app messages — becomes part of a searchable archive of information. To keep that archive useful as it grows, Slack uses machine learning to hone in on exactly what you’re looking for: So the more you use it, the better it gets.

All of the above, at Enterprise scale

Slack Enterprise Grid features all the benefits of Slack, but with far more options to customise workspaces for every team and department. Give all the parts of your business space to focus on their work , create shared channels between these workspaces, and provision security controls across your entire organisation.
