This tech firm rationalizes its collaboration stack case study is an anonymised composite, built from our engagements to illustrate a common situation. It is not a named client, and the savings are shown as ranges rather than exact figures. The pattern, though, is real and recurring: a growing technology company that accumulated overlapping collaboration tools faster than anyone reviewed them.
Situation
A technology firm of roughly 1,100 employees across three offices had grown quickly. Different teams had adopted their own tools along the way. The company ran Slack for chat, Zoom for video meetings, and a separate webinar platform, while also holding Microsoft 365 licences that already bundled Teams for both chat and meetings. Nobody owned the collaboration stack as a whole, so each tool renewed on its own date and the total spend was never looked at together.
The overspend found
The review found duplication on three fronts. Chat ran on Slack while Teams chat sat paid for and largely unused inside the Microsoft 365 licences. Meetings ran on Zoom while Teams meetings were also available at no extra licence cost. And the standalone webinar tool overlapped with capability the firm could access through its existing platforms for most of its use cases. On top of the duplication, a meaningful share of Slack and Zoom seats were inactive, belonging to people who had left or moved teams while their seats stayed billed. The renewal dates were scattered across the year, so the firm negotiated each contract alone with no leverage.
Approach
We treated this as a stack decision rather than a series of single vendor cuts, the approach set out in our collaboration tool rationalization service and connected up into the bundled digital workplace cost optimization view. First we measured real usage of every tool and identified the teams with a genuine dependency, such as the engineering groups relying on specific Slack integrations and the marketing team running large external webinars. Then we decided the standard for each capability, defaulting to the tools already paid for in Microsoft 365 where they met the need, while protecting the justified exceptions. We reclaimed the inactive seats immediately, applied the discipline in internal chat tool rationalization to the chat overlap, and timed the Slack and Zoom reductions to their renewals using the leverage described in negotiating Slack enterprise renewals.
Outcome
The firm reduced its collaboration tooling spend by a range of 30 to 40 percent. It consolidated three overlapping categories onto Teams for the bulk of chat and meetings, retained a small justified Slack footprint for the engineering teams with a real integration dependency, and kept a limited webinar capability only where the existing platforms could not serve the use case. It reclaimed several hundred inactive seats across Slack and Zoom. It also aligned the remaining renewal dates so future negotiations happen as a portfolio rather than one contract at a time. The figures are illustrative ranges drawn from a composite, not a single client's books.
Lessons from how this tech firm rationalizes its collaboration stack
Three lessons carry across. First, the largest collaboration savings usually come from removing duplication, not from negotiating a single tool harder, because companies so often pay for capability already bundled into Microsoft 365. Second, protecting genuine dependencies is what makes a large reduction safe: the goal is to right size to real need, not to strip tools people rely on. Third, scattered renewal dates and unowned tools are how the waste accumulates, so assigning an owner and aligning renewals is what stops it returning. For any contract wording, the firm relied on its own counsel, since our work is commercial and cost advisory rather than legal advice.
