Building a robust streaming app like Disney+ or Netflix involves a comprehensive, step-by-step process that integrates user experience, content management, and real-time data analytics. Whether you're a senior executive, data strategist, or engineer, understanding how each piece fits together is essential to success. In this article, we will explore the key steps, best practices, and questions you should ask during each phase of development to ensure your app meets the growing demands of today's media landscape.
1. Define Business Objectives
The foundation of a successful streaming app lies in its business objectives. Begin by asking yourself: What are the goals of this app? Are you aiming to increase subscriptions, reduce churn, or expand your market presence? For example, Disney+ focuses on family-oriented content and bundled subscriptions with Hulu and ESPN+ to maximize market penetration.
Once you've defined your goals, focus on core business drivers—content recommendations, personalization, and cross-platform accessibility. From a UX perspective, maintaining a consistent design across platforms like Samsung, LG, and Roku is crucial. Additionally, implement data strategies that track user engagement metrics such as watch time, conversion rates, and retention. Ensure the backend architecture (built with Python or Go) integrates with content management systems (CMS) and is scalable using container orchestration platforms like Kubernetes.
Key Question: What specific user engagement metrics will we focus on to drive growth and retention?
UX Design Instructions
Establish a consistent UI/UX across all Smart TV platforms (e.g., Samsung, LG, Roku) while ensuring user-friendly navigation and immersive design.
Data Strategy and Instructions

Engineering and Coding Instructions
Use Python or Go for backend microservices. Build APIs to connect with content management systems (CMS) and monitor the performance metrics relevant to business goals. Ensure scalability by integrating with container orchestration platforms like Kubernetes.
2. Select TV Platforms
Choosing the right Smart TV platforms is another critical decision. You must ask: Which platforms offer the best opportunities for market growth? Conduct demographic research and usage statistics to prioritize your development efforts. For instance, if most of your audience uses Roku, prioritize its development, but don’t ignore niche markets like Samsung Tizen or LG webOS.
Ensure your design is adaptable, considering the unique interface interactions across different remote controls and devices. Platform-specific SDKs (e.g., Roku SDK, Tizen SDK) are essential for native development, but consider cross-platform frameworks like React Native TV to reduce development costs.
Key Question: Which Smart TV platforms should we prioritize based on our target demographics?
