SaaS Explained in 30 Seconds

SaaS means software delivered online via subscriptions instead of one-time licenses. Customers pay for ongoing access, updates, and support. This model is common across CRM, collaboration, security, and analytics products.

Why SaaS Matters

SaaS matters because recurring revenue changes how companies build and measure growth. Strong retention creates compounding revenue over time. In conversation, SaaS usually means balancing acquisition speed with long-term retention quality.

What People Usually Mean When They Mention SaaS

In business discussions, SaaS means MRR, ARR, churn, and expansion revenue. In product discussions, it means onboarding and stickiness loops. In investor talks, it means revenue durability and margin potential.
