Source: Torii Research, anonymized and aggregated usage data. Published August 1, 2025. Summary figures computed from the 30 apps in this report.
What the data says
Google AI Studio leads with a viral score of 6.2 and doubles its users inside an organization in 11.7 days on average, ahead of NotebookLM at 5.8 and OpenAI at 5.3.
DeepSeek spreads almost as fast, doubling in 12.1 days, against a median of 70.5 days across the 30 apps. IT & Security (8) and Productivity (7) are the largest categories.
Most apps are well covered: 26 of the 30 claim at least two of SOC 2, ISO 27001, and GDPR, and none scores 70 or higher on the Shadow IT index. The ones to watch are DeepSeek, Lovable, n8n, and Read AI, which score between 40 and 69 with at most one compliance claim.
This report ranks the apps spreading fastest inside organizations, based on anonymized, aggregated usage data from August 2024 to August 2025.
Bottom line
Viral adoption in 2025 concentrates in AI-forward productivity and developer tools. Most of these apps claim strong compliance coverage, but four fast-spreading apps with elevated Shadow IT scores claim little: DeepSeek, Lovable, n8n, and Read AI.
