Zylo·high signal

Zylo's eighth annual SaaS Management Index reveals organizations now spend $55.7M on SaaS annually (+8% YoY), but portfolio app counts dipped just 0.07% to 305 — meaning existing apps are getting more expensive, not that orgs are adding tools. AI-native application spend jumped 108% overall and 393% for large enterprises. AI category usage grew 181%, the fastest in the dataset. 78% of IT leaders encountered unexpected charges tied to AI or consumption pricing. ChatGPT is now the most expensed application across enterprises.
