What happened
When Satya Nadella became CEO in February 2014, Microsoft was profitable but stagnant. It had largely missed smartphones and search, and its internal culture was known for competing divisions protecting Windows.
Nadella set a ‘mobile-first, cloud-first’ direction. Microsoft released Office for the iPad within weeks, embraced Linux and open source, and wrote off about $7.6 billion on its Nokia phone purchase in 2015. It moved Office to Microsoft 365 subscriptions and invested heavily in the Azure cloud. Nadella promoted a ‘growth mindset’ culture, borrowing from psychologist Carol Dweck.
Acquisitions including LinkedIn (about $26.2 billion) and GitHub (about $7.5 billion) added platforms with loyal users. An early, large investment in OpenAI positioned Microsoft at the front of the AI wave. Microsoft's market value passed $1 trillion in 2019 and $3 trillion in 2024.
