Slack Valuation And Public Market Impact
From Glitch To Enterprise-Grade Messaging
Slack’s direct listing and subsequent IPO delivered substantial paper wealth for shareholders, including Butterfield, whose holdings were revalued on the open market. The listing also increased media scrutiny on executive compensation and long-term shareholder returns.

With the acquisition, Butterfield’s net worth was re-anchored to cash and Salesforce shares, subject to market fluctuations in the parent company. This shift made his wealth more legible to public benchmarks such as Forbes rankings.
