Documented cause
Busuu, a London-based language learning platform co-founded by Bernhard Niesner and Adrian Hilti, raised over $30M and built a community of 120M registered users. In January 2022, Chegg acquired Busuu for $436M as part of its international expansion strategy. While technically a successful exit, Busuu was functionally absorbed and lost its independence. By late 2023, Chegg's own collapse undermined Busuu's strategic position, with its future tied to a struggling parent.
Lesson
“Strategic acquisitions that look like wins can become liabilities when the acquirer is disrupted.”
