Our expertise
Digital Products
We craft digital products and bespoke digital companions to physical products.
Shaping digital experiences that connect, perform, and scale.
We design and develop thoughtful digital products — from strategy to launch and beyond. Whether it’s a connected mobile app, a dynamic website, or a digital layer for a physical product, we help our clients bring ambitious ideas to life.
As the boundary between digital and physical continues to dissolve, products are no longer standalone artifacts. They’re platforms for experience, interaction, and growth. That’s why we approach digital with a product mindset: strategically designed, beautifully executed, and built to evolve.
We bridge vision and reality — combining UX/UI design expertise, cutting-edge technology, and deep business understanding to deliver impactful, scalable digital solutions.
Our Digital Product Development Process
At Propeller, we've refined our digital product development process through years of experience working with startups and enterprises across Stockholm and globally. Our approach ensures that every digital product we create is not just technically sound, but also delivers real value to users and businesses.
Every successful digital product begins with deep understanding. We immerse ourselves in your business context, user needs, and market dynamics. Through stakeholder interviews, user research, and competitive analysis, we uncover insights that shape product strategy. This phase includes technical feasibility studies, business model validation, and roadmap planning.
Our UX/UI design process transforms insights into tangible experiences. Starting with user journey mapping and wireframes, we iterate through interactive prototypes that bring ideas to life. Our Stockholm design team applies Scandinavian design principles — clarity, simplicity, and functionality — while ensuring your brand identity shines through. Usability testing validates our design decisions before development begins.
We build digital products using modern, scalable technologies. Our agile development approach ensures transparency and flexibility throughout the process. Whether it's a React-based web application, React Native mobile app, or complex IoT integration, we maintain high code quality through automated testing, code reviews, and continuous integration practices.
Launching is just the beginning. We ensure smooth deployments with comprehensive testing, performance optimization, and monitoring setup. Our team provides launch support, user onboarding strategies, and analytics implementation to track key metrics from day one.
Digital products must evolve with user needs and market changes. We offer ongoing support, feature development, and optimization based on real user data and feedback. Our iterative approach ensures your digital product remains competitive and continues delivering value.
