Documented cause
Cybereason was an endpoint detection and response (EDR) cybersecurity company founded by Israeli intelligence veterans, backed by $900 million from SoftBank Vision Fund and Google. The company was valued at $3 billion+ and employed 1,700 people at peak. In 2022, Broadcom explored acquiring Cybereason but the deal collapsed — reportedly due to valuation disagreements after Broadcom acquired VMware instead. Following the failed acquisition, Cybereason underwent mass layoffs in 2022 (cutting 10% then 17% of staff), closed offices, and dramatically contracted its go-to-market. The cybersecurity market had consolidated around CrowdStrike and SentinelOne with network effects Cybereason could not overcome despite genuine technology. By 2023, the company was a shadow of its peak.
Lesson
“Building your company for an acquisition rather than for profitability creates a binary outcome: either the acquirer comes, or you are over-staffed, over-capitalized, and structurally unable to survive as an independent company.”
