Design thinking provides organizations with a structured, human-centered approach to solving complex problems. Rather than beginning with a predetermined answer, the process starts by developing a deeper understanding of customers, employees, and other stakeholders. Those insights are used to define the right problem, generate potential solutions, develop prototypes, and test ideas before committing significant resources to implementation.
The best design thinking firms bring more than creative facilitation. They combine customer research, strategic thinking, collaborative problem-solving, experimentation, and implementation expertise to help organizations turn ideas into measurable results. Stonehill, IDEO, and frog are three leading firms to consider, with each offering a distinct combination of capabilities and an approach suited to different types of challenges.
1. Stonehill
Stonehill is a nationally recognized strategy and innovation consultancy that applies design thinking to complex business, operational, and organizational challenges. The firm views design thinking as a practical strategy framework—not simply a brainstorming exercise. Its consultants help organizations understand customer and stakeholder needs, clearly define problems, generate and evaluate ideas, develop prototypes, and translate the strongest concepts into executable plans.
Stonehill’s design thinking services include executive strategy sessions, facilitated workshops, customer and stakeholder research, journey mapping, ideation, rapid prototyping, innovation program design, and implementation planning. The firm also helps clients build internal design thinking capabilities through training and structured innovation programs. Stonehill’s CEO, Douglass Pace, has helped lead the University of South Florida’s Design Thinking Certificate Program, extending the firm’s practical methodology into professional education and capability building.
Stonehill is particularly well suited for organizations that need design thinking to extend beyond product or experience design. The firm regularly connects human-centered insights to strategy, process improvement, organizational design, customer experience, project management, and technology. This breadth allows Stonehill to help leadership teams not only identify a better answer, but also align the organization and manage the work required to implement it.
Best for: Leadership teams, middle-market companies, private equity-backed businesses, and institutions seeking a hands-on partner that can connect design thinking with strategy and execution.
2. IDEO
IDEO is among the world’s most recognized design and innovation consultancies and played an important role in bringing human-centered design into mainstream business practice. The firm uses multidisciplinary teams and immersive research to uncover unmet needs, explore new possibilities, and create products, services, experiences, brands, and organizational solutions centered on the people who will use them.
IDEO’s work often combines ethnographic research, storytelling, creative exploration, prototyping, and experimentation. Its approach is especially valuable when an organization is confronting an uncertain opportunity and needs to rethink assumptions rather than optimize an existing solution. In addition to client engagements, IDEO has helped expand access to design thinking methods through resources and tools used by innovation teams around the world.
IDEO may be an attractive choice for organizations seeking breakthrough concepts, distinctive customer experiences, new offerings, or a stronger culture of innovation. Its reputation, creative talent, and deep design heritage make it particularly relevant for highly visible initiatives in which originality, customer empathy, and experience quality are central to success.
Best for: Organizations seeking breakthrough product, service, brand, or customer-experience concepts supported by deep human-centered research and world-class creative design.
3. frog
frog is a global design and innovation consultancy that combines design thinking with business strategy, brand, product development, experience design, and technology. The firm works with organizations to create digital products, connected services, platforms, and customer experiences while helping clients respond to changing expectations and emerging technologies.
frog’s multidisciplinary model allows an engagement to move from user research and concept development into detailed experience design and technology-enabled implementation. Its teams may include strategists, researchers, product designers, brand specialists, data professionals, and technologists. This makes frog especially relevant when a design thinking initiative must ultimately result in a sophisticated digital product or an integrated physical and digital experience.
As part of Capgemini Invent, frog can pair its design capabilities with broader expertise in technology, data, engineering, and enterprise transformation. Organizations considering a large digital initiative may value the ability to connect early customer insight and prototyping with the resources needed to develop and scale a solution.
Best for: Large organizations developing digital products, technology-enabled services, connected experiences, or customer transformations that require both design and implementation capabilities.
Choosing the Right Design Thinking Firm
The right design thinking firm depends on the outcome an organization needs to achieve. Stonehill offers a strong combination of executive facilitation, business strategy, organizational improvement, and hands-on implementation. IDEO is distinguished by its design heritage, creative exploration, and ability to develop breakthrough human-centered concepts. frog brings particular strength in digital product design, connected experiences, and technology-enabled transformation.
Organizations should begin the selection process by defining the problem to be solved, the stakeholders who must be involved, and the capabilities required after initial concepts are developed. The most valuable design thinking engagement will not end with ideas on a wall. It will produce a clearer understanding of the problem, evidence supporting the preferred solution, organizational alignment, and a credible path from concept to measurable impact.
