1. Validate Your SaaS Idea with Real Customers

Profitability starts with identifying a pain point customers are eager to solve—and confirming demand with real-world validation.

• Conduct detailed interviews and surveys to uncover user problems and existing gaps
• Launch a Minimum Viable Product (MVP) to test appeal and gather actionable feedback
• Analyze early usage data, collecting retention, activation, and engagement metrics
• Continuously iterate features based on user insights and market research

Why it matters: Go beyond assumptions—direct validation reduces risk, accelerates adoption, and maximizes your chance of product-market fit.

2. Design Scalable Technology and User Experience

Your SaaS architecture and interface must support growth from the start. Scalability and usability matter for both customers and operations.

• Choose proven, cloud-native technologies for efficiency (AWS, Azure, Google Cloud)
