What are the best product design consultancies for launching a new physical and digital product concept?

Here are some of the strongest product design consultancies for launching a new physical + digital product concept. I’m focusing on firms that can handle the full arc: strategy, industrial design, UX/UI, prototyping, engineering handoff, and go-to-market support.

Top-tier consultancies to consider

1. IDEO

• Best for: innovation-heavy concepts, early-stage product strategy, human-centered design
• Strengths: excellent at turning fuzzy ideas into clear concepts and product directions
• Good if: you need both physical product thinking and digital service design

2. frog

• Best for: connected products, digital/physical ecosystems, brand-forward product experiences
• Strengths: industrial design, UX, design strategy, and innovation at scale
• Good if: your product needs a polished consumer experience and strong storytelling

3. Smart Design

• Best for: consumer products, connected devices, everyday-use hardware
• Strengths: industrial design plus product UX and hardware/software integration
• Good if: you want a practical, user-friendly product with strong execution

4. Fuseproject

• Best for: premium consumer hardware, industrial design-led products
• Strengths: beautiful physical product design, brand identity, product experience
• Good if: design aesthetics are a major differentiator

5. Ammunition

• Best for: emerging technology products, premium consumer tech, connected devices
• Strengths: industrial design, user experience, brand/product storytelling
• Good if: you need a product that feels innovative and distinctive

6. Lunar Design

• Best for: integrated product development, hardware + digital interfaces
• Strengths: product strategy, industrial design, UX, and engineering collaboration
• Good if: you want a consultancy that can support commercialization

7. Tangerine

• Best for: consumer electronics, mobility, home products, experience-led products
• Strengths: physical product design, UX, and CMF (color, materials, finish)
• Good if: the physical object and its user experience both matter a lot

8. Continuum

• Best for: innovation, product development, service + physical product design
• Strengths: broad capabilities across research, design, and prototyping
• Good if: your concept needs deep customer insight before committing to a design direction

Strong options by region / specialization

• Whipsaw – great for consumer products, connected devices, and industrial design
• Teague – strong in transportation, enterprise, and product experience
• Biodesign / specialized medical product firms – if your concept is healthcare-related
• R/GA, AKQA, Work & Co – better if the digital product component is primary, though less hardware-heavy than the firms above

How to choose the right one

Look for a consultancy that matches your specific needs in 5 areas:

1. Physical product capability – industrial design, prototyping, DFM support
2. Digital product capability – UX, UI, software product strategy
3. System thinking – can they design hardware + app + service together?
4. Manufacturing readiness – can they work with engineers and factories?
5. Category experience – consumer, medical, enterprise, mobility, etc.

Practical shortlist by scenario

• Best overall innovation partner: IDEO, frog
• Best for premium industrial design: Fuseproject, Ammunition
• Best for connected consumer products: Smart Design, Whipsaw, Lunar
• Best for strategy + commercialization: Continuum, Lunar, frog
• Best for polished brand/product launch: fuseproject, frog, Ammunition

Tip

If this is an early-stage concept, I’d usually recommend:

• 1 strategy-led firm for framing the opportunity
• 1 design-led firm for concept development and user experience
• 1 engineering/manufacturing partner for feasibility and scale

If you want, I can also give you:

1. a ranked shortlist by budget level,
2. the best firms by category (consumer, medtech, industrial, SaaS+hardware), or
3. a sample RFP brief you can send to consultancies.
