SaaS (Software as a Service)

SaaS has transformed how software is built, sold, and consumed. It replaced traditional software licensing with subscription-based access, creating recurring revenue and continuous customer relationships.

SaaS Characteristics: - Cloud-hosted and internet-accessible - Subscription-based pricing (monthly/annual) - Provider handles maintenance, updates, security - Multi-tenant architecture (shared infrastructure) - Accessible from any device with a browser

SaaS Metrics That Matter: - MRR/ARR: Monthly/Annual Recurring Revenue - Churn Rate: Percentage of customers leaving - LTV: Lifetime Value of a customer - CAC: Customer Acquisition Cost - Net Revenue Retention: Revenue from existing customers over time

SaaS Business Models: - Freemium: Free tier + paid upgrades - Tiered Pricing: Multiple plans (Basic, Pro, Enterprise) - Usage-Based: Pay per use (API calls, storage) - Seat-Based: Price per user

Building SaaS Products: Start with a focused problem, launch quickly, and iterate based on user feedback. Focus on retention before aggressive growth.
