Failures & Challenges
The chapters most pages skip.
No journey is a straight line. The setbacks weren't detours — they were the route.
Tumblr acquisition writedown
Context
Wrote down most of the $1.1B Tumblr purchase by 2016.
Recovery
Sold to Automattic in 2019 under Verizon ownership.
Lesson
Cultural-fit and integration plan should be a board-level diligence item before price.

Context
A breach affecting 500M accounts came to light during the Verizon sale.
Recovery
Negotiated a $350M reduction in deal price; coordinated security overhaul.

Recovery

Lesson
Restructuring requires a narrative the team can keep retelling internally.
