TL;DR
Design Thinking remains essential in 2026, but it is now combined with AI (such as Claude) and A/B testing to move from generating ideas to validating them quickly. The companies that innovate today are not the ones with the most ideas, but the ones that experiment, measure and learn faster.
Introduction
In recent years, we’ve seen how artificial intelligence has transformed the way companies generate ideas, design products and make decisions. Today, it’s possible to create prototypes in hours, automate complex processes and launch digital solutions at a speed that would have been unthinkable just a few years ago.
However, one thing hasn’t changed: the difficulty of truly understanding what users need.
In this context, Design Thinking is not only still relevant, but more necessary than ever. Because while technology accelerates execution, the real challenge remains defining the problem correctly and validating that the solution makes sense.
Far from being a “creative” methodology of the past, Design Thinking has become a strategic tool that connects innovation, business and users within the same process.
What is Design Thinking
Design Thinking is a way of approaching complex problems by putting the user at the center of the entire process. It’s not just about generating ideas, but about deeply understanding needs, challenging assumptions and building solutions that actually work in practice.
Unlike more traditional approaches, it doesn’t start from what a company wants to build, but from what the user needs to solve.
More than a rigid methodology, Design Thinking works as a mindset that combines:
empathy
creativity
experimentation
validation
In 2026, it naturally integrates with tools such as A/B testing, data analysis and artificial intelligence, allowing teams not only to ideate, but also to measure and continuously optimize.
Current examples of Design Thinking in action
To understand how it’s applied today, it’s important to move beyond classic examples and look at how digital companies operating in complex and competitive environments are using it.
Spotify: designing experiences that evolve with the user
Spotify doesn’t design static products. It designs systems that learn. The key lies in how it combines Design Thinking with data. It doesn’t just try to understand what the user wants at a specific moment, but observes how habits evolve and adapts the experience accordingly.
Features like Discover Weekly or personalized recommendations don’t come from a single big idea, but from a continuous process of observation, experimentation and iteration.
Here, design never really ends. It constantly adapts based on real user behavior.
Notion: simplicity as a competitive advantage
Notion is a great example of how innovation doesn’t always mean adding complexity. Its success comes from understanding something simple: users needed a flexible tool that adapts to how they work, not the other way around. Through constant iteration, they’ve built a platform that allows users to organize information, collaborate and create their own systems.
What’s interesting is that many of their improvements don’t come from internal decisions, but from observing how users interact with the product and adjusting the experience accordingly.
Google Antigravity (AI-first platforms): Designing human-AI interaction
New AI-first platforms like Antigravity are redefining Design Thinking entirely. The challenge is no longer just designing interfaces, but designing how humans interact with intelligent systems. This involves working on aspects that didn’t exist before, such as:
how to structure prompts
how to shape responses
how to guide users in open environments
In this context, Design Thinking becomes more dynamic: a process where design, technology and user behavior continuously adapt in real time.
Amazon: eliminating friction as a design strategy
Amazon has been applying Design Thinking for years, but in a subtle way.
Its goal is not to impress users, but to remove friction. From checkout to recommendations, everything is designed to make decisions easier. What’s most interesting is that every small change is constantly validated.
Here, design is not a phase, it’s an ongoing system of improvement.
Digital startups: Validating before building
In the startup ecosystem, Design Thinking has evolved into something more practical: validating before scaling.
Instead of building full products from the beginning, many companies start with:
an idea
a simple prototype
testing with real users
And then iterate.
This approach reduces risk and accelerates learning. This is where Design Thinking connects directly with idea validation and experimentation. Something more and more companies are adopting.
The 5 stages of Design Thinking
Although traditionally presented as five stages, in practice they are not linear steps but parts of a continuous system.
Empathize
Everything starts with understanding the user, not through assumptions but through real data, behavior and context.
Define
Once the problem is understood, the challenge is to frame it correctly. Often, the real value lies in redefining the question.
Ideate
This is where possible solutions are generated. In 2026, this phase is heavily supported by AI tools, although human judgment remains essential.
Prototype
Ideas become tangible. This can range from simple mockups to fully functional MVPs.
Test
Solutions are validated with real users. This is where interesting ideas are separated from those that truly work.
What is Design Thinking used for in companies today
In a business context, Design Thinking is used to address innovation challenges and opportunities within the organization. Here are some of its practical applications:
Product and Service Development
Design Thinking helps companies develop products and services that align with customer needs and desires. By deeply understanding users, opportunities can be identified to create solutions that solve real problems and provide an exceptional experience.
Customer Experience Improvement
Design Thinking's user-centered approach allows companies to understand customer interactions and experiences at every touchpoint. This helps identify and address areas for improvement, optimizing the customer experience and increasing satisfaction and loyalty.
Internal Innovation
Design Thinking is also applied to foster internal innovation within organizations. By involving employees in the Design Thinking process, their creativity is stimulated and they are encouraged to propose innovative ideas. This promotes a culture of innovation and allows companies to leverage the knowledge and experience of their own teams.
Solving Complex Problems
Businesses often face complex challenges that require creative and unconventional solutions. What is Design Thinking if not a structured framework for effectively addressing these problems? By adopting an iterative approach to prototyping and testing, businesses can explore different approaches and find viable solutions.
Collaboration and Teamwork
Design Thinking promotes collaboration and teamwork. By involving people from different disciplines and perspectives in the design process, more diverse ideas are generated, and co-creation is encouraged. This strengthens collaboration and knowledge sharing among teams, driving creativity and collaborative problem-solving.
Focus on User Satisfaction
Design Thinking places special emphasis on understanding and addressing user's needs and desires. By prioritizing user satisfaction, businesses can build products and services that meet market demands and generate a competitive advantage.
Why Design Thinking is more important than ever in the age of AI
Artificial intelligence has changed the pace of innovation. Today, ideas, prototypes and solutions can be generated in hours. But that doesn’t guarantee relevance.
This is where Design Thinking becomes even more important. It allows companies to filter, validate, and prioritize in an environment where possibilities are nearly endless.
In other words, AI helps you create faster, but Design Thinking helps you create better.
Design Thinking, A/B testing, and Claude: the winning combination
In recent months, we’ve been hearing everywhere about tools like Claude and how revolutionary they are. They have changed the way we design products and digital experiences. Today, generating ideas and prototypes takes minutes. But this has made one thing clear: having many ideas is no longer enough. The real difference lies in knowing which ones work.
This is where Design Thinking, A/B testing and AI come together. While AI enables rapid exploration of solutions, A/B testing helps validate them with real data, all within a user-centered approach.
This model is transforming innovation. Companies are moving away from long, linear processes and toward shorter cycles of ideating, testing and learning continuously. Because today, innovation is not about having the best idea, but about building a system that allows you to learn faster than others.

Conclusion
Design Thinking has evolved. It is no longer just a creative methodology, but a way of working that combines intuition, data, and experimentation. The companies that are truly innovating today are not those with the most ideas, but those that know which ideas are worth developing.
And that only happens by understanding users, validating solutions and continuously improving. In a fast-changing environment, the advantage is not getting it right the first time, it’s learning faster than everyone else.
