Why We're Only Just at the Beginning of SaaS
We may have been talking about SaaS companies for more than a decade, but we’re still just at the beginning. The legacy software companies including Oracle, Microsoft, SAP and and IBM control 83% of the market cap of software businesses, representing $830B in market cap. The largest SaaS company, Salesforce, is just about half the size of SAP, and Microsoft is 8x bigger.
In revenue terms, the legacy vendors control an astounding 93% of revenue: $245B compared to $19B.
