Are you an entrepreneur navigating the complex landscape of 2025, looking to build a sustainable, impactful startup? Are you struggling with problem-solving, project management, or fostering a culture of creativity?
If so, Design Thinking could be the game-changer you need to overcome these challenges and unlock smarter, faster, and more realistic solutions. This blog post explores how adopting Design Thinking can set your startup up for success in 2025 and beyond.
What is Design Thinking?
Design Thinking is more than just a process; it’s a mindset - a human-centered approach to problem-solving that prioritizes empathy, experimentation, and iteration. Unlike traditional linear problem-solving methods, Design Thinking encourages a cyclical process. This iterative process ensures continuous improvement, helping you create solutions that address your audience’s problems.
The Five Phases of Design Thinking for Startups

1. Empathize
Understand the needs and motivations of your target audience by immersing yourself in their world. This could involve conducting interviews, shadowing potential customers, or using data analytics to uncover pain points and preferences.
Identifying these pain points ensures you're solving meaningful problems that resonate with your audience - key to the success of any sustainable startup.
This step is vital for customer-centric solutions and will play a major role in entrepreneurship in 2025.
2. Define
Clearly articulate the problem your startup aims to solve.
Frame the pain points uncovered during the Empathize phase into a concise problem statement.
For example, if your startup focuses on eco-friendly packaging, you might define the problem as: “Businesses struggle to find sustainable yet affordable packaging options”.
This clarity ensures your team stays aligned and focused on innovative solutions.
3. Ideate
This phase encourages creative problem-solving techniques to foster startup innovation.
Think BIG. Break boundaries and unleash creativity using bold techniques like mind mapping or SCAMPER.
Building on the example of affordable sustainable packaging, consider ideas like:
Partnering with local farmers to repurpose agricultural waste into biodegradable materials
Creating a community recycling program where customers exchange used materials for discounts
Collaborating with artists or schools to turn scrap packaging into reusable products
Don’t just solve the problem—redefine what’s possible by considering a wide range of solutions and evaluating their feasibility.
4. Prototype
Create low-cost prototypes to quickly test your ideas and validate assumptions.
For our sustainable packaging example, you could:
Craft small batches of biodegradable packaging from agricultural waste to test durability
Develop a prototype recycling exchange platform to gauge customer engagement
Prototyping allows you to turn concepts into tangible solutions, which helps minimize risks while innovating for your sustainable startup.
5. Test
Collect user feedback to refine and perfect your solution.
Engage your target audience to validate whether your prototype addresses their pain points.
For example, testing a recycling exchange platform could involve:
Pilot launch: Start small to gather real-world feedback
User testing: Have your target users interact with the platform and observe their experience
Feedback collection: Use surveys, interviews, and focus groups to gather insights
Key metrics: Measure engagement levels and satisfaction to identify areas for improvement
Refinement and iteration are crucial for aligning with customer expectations and scaling your human-centered design process effectively.
Why Startups Need Design Thinking to Innovate in 2025
Minimizes the Risk of Building the Wrong Product
Design Thinking helps you validate your ideas early on by gathering feedback from real users. By focusing on empathy and understanding customer needs, you avoid the costly mistake of building a product that no one wants. This iterative approach dramatically reduces the risk of failure.
Enables Quick, Low-Cost Iteration
Design Thinking promotes rapid prototyping and testing, allowing you to build functional versions of your ideas at low cost. This iterative process allows you to learn quickly from your mistakes, and improve your product before committing large resources. It’s a smarter way to turn concepts into products without wasting time or money.
Builds a Loyal Customer Base and Strong Brand Image
By involving customers in the process, Design Thinking ensures your product resonates deeply with them. This fosters trust and satisfaction, leading to stronger customer loyalty. When customers feel heard and valued, they are more likely to stay engaged, advocate for your brand, and continue using your product for the long term.
Data Speaks: The Impact of Design Thinking on Startups
A McKinsey & Company study found that companies prioritizing design saw 32% higher revenue growth and 56% higher shareholder returns than competitors.
(While the McKinsey Design Index (MDI) doesn’t explicitly use the term "Design Thinking," it measures the implementation of practices that are core to Design Thinking - offering a tangible way to measure the benefits of adopting this approach.)

Real-World Example - TômTex
TômTex is a pioneering startup dedicated to creating sustainable, high-quality, and cost-effective vegan leather alternatives. Founded by Vietnamese designer Uyen Tran, the company utilizes chitosan derived from shell seafood waste and mushrooms to produce eco-friendly materials that mimic the look and feel of traditional leather.
TômTex's innovative process embodies the principles of Design Thinking:
Empathy: Recognizing the environmental impact of traditional leather production, TômTex seeks to address the fashion industry's reliance on fossil fuel-derived materials.
Define: The company identifies the need for sustainable, biodegradable, and durable materials in fashion, aiming to reduce waste and environmental harm.
Ideate: By exploring natural waste products like shellfish and mushrooms, TômTex develops alternative materials that are both functional and eco-friendly.
Prototype: The startup creates samples of its materials, collaborating with designers to test and refine their products.
Test: Through partnerships with fashion brands and designers, TômTex gathers feedback to enhance the performance and appeal of its materials.
Their design process emphasizes understanding environmental needs, experimenting with novel materials, and continuously refining their products. This human-centered approach has allowed TômTex to create an innovative solution that aligns with both user needs and eco-friendly goals.
In July 2024, TômTex formed collaborations with Sky High Farm Universe and Parley, showcasing products like bomber and puffer jackets made from their sustainable materials. The company is set to launch its first commercial product in spring 2025 and is exploring potential partnerships beyond the fashion industry
