I really love Slack for its comprehensive tools that boost team collaboration from channel creation that helps to handle multiple projects through organized conversations.

“Slack gets the job done -But a smarter AI would trigger some of the features I specified.”
Slack is a reliable communication tool that helps teams organize and connect. Channel structure and integrations are really good for day-to-day tasks. However, Ai should take place in the slack for better performance of the app.

What Your Peers Are Saying About Slack
VP of IT
I am revisiting our messaging retention thresholds more specifically for email (Google) and instant messaging (Slack). Was curious as to what is generally being used as the threshold for these 2 communications tools (i.e.; 30 days, 6 months, etc.)?Director of IT
See Full DiscussionI also am curious what other organizations are doing on this front. We had an event where legal had us put an indefinite hold on all messages (email, IM, etc) and now that has just become the standard. Would like to compare what other organizations are doing and try to get us back to something that doesn't hold messages forever.
VP SALES OPERATIONS & ENABLEMENT
Does anyone have experience with Slack Sales Elevate or Slack AI? If so, did you see any productivity improvements, specifically for Sales? We are looking at Sales Elevate for a few specific use cases: (1) Deal Desk efficency improvements; (2) Summaries of changes made to opportunities for sales leaders; (3) Account planning (there are collaborative templates in Sales Elevate which you can configure to meet your org's needs). We're also interested because it seems like an easy way to start using AI in a fairly low risk area. For context, we use SFDC CRM already. Founder
See Full DiscussionBeen disappointed by it honestly, especially when compared to Momentum.io it doesn’t even come close.

Intuitive Features Like Huddles Stand Out Despite Slack’s Premium Pricing Concerns
SLACK remains the gold standard for team culture and rapid-fire communications. My overall experience is that it is the most "human-centric" tool in the enterprise space.
