What buyers actually pay for Slack, quarter by quarter: the median paid price as a line, the negotiated corridor as a band, and the observations behind every figure. Published quarterly, versioned, and never restated.
Business+ and Enterprise agreements, indexed through the Business+ public list anchor. Each quarterly stamp aggregates the trailing four quarters of observed agreements from the VendorBenchmark outcome network and curated reference book, publishes only above our density thresholds, and never extrapolates into thin cells. The full rules are on the methodology page.
