Design agencies make products beautiful. Model T makes products possible. In B2B hardware, architecture comes before aesthetics.
Premium design agencies are masters of user experience, industrial design, and design strategy. A full engagement — discovery, user research, concept exploration, prototyping, design language development — runs €300K–800K over 3–6 months. The deliverables are compelling: renderings, user flows, ergonomic studies, and design specifications that guide product development.
For consumer electronics, this investment often makes sense. The iPhone wasn't just engineered — it was designed. But in B2B hardware — industrial controllers, embedded gateways, BMS modules, FPGA-based video processors — the buying decision rarely hinges on industrial design. It hinges on architecture: can the system meet latency requirements, power budgets, certification constraints, and integration demands?
Design agencies typically lack the embedded systems expertise to address these questions. They can sculpt an enclosure but not specify an FPGA fabric. They can map a user journey but not define a power architecture. And they operate on a time-and-materials model with no pay-on-acceptance option — the €300K is committed regardless of whether the design translates into a viable engineering concept.
Model T starts where design agencies stop: at the system architecture level. Each pursuit delivers 2–3 product concepts that include block diagrams, preliminary component selection, power budget estimates, interface definitions, and a competitive technical analysis. These are the artifacts that B2B hardware buyers actually evaluate when deciding whether to engage.
The 18-step pipeline across 6 stages covers the full concept development arc: lead qualification, company and market research, insight generation, technical architecture, business case development, and mini-offer packaging. The cross-functional team — business analyst, product manager, senior engineer — draws on Promwad's 20 years of embedded systems experience and 500+ completed projects.
At from €15K per pursuit with a 2–3 week timeline and pay-on-acceptance pricing, Model T addresses the B2B hardware market's actual need: engineering credibility, not design polish. For companies selling into industrial, automotive, or medical markets, the prospect needs to see that you understand their technical constraints — not that you can render a beautiful enclosure.
Design agencies are indispensable when the product's success depends on user experience and industrial design — consumer electronics, wearables, smart home devices. Model T is the right tool when the buyer's decision hinges on engineering credibility: can you meet their power budget, latency requirements, certification constraints, and integration timeline? In B2B hardware markets — semiconductor design-in, industrial automation, automotive electronics, medical devices — the architecture concept is the sales tool, not the rendering. Organizations that invest in design agency engagements for B2B hardware sales are solving the wrong problem. The prospect doesn't need to see that your product is beautiful. They need to see that you understand their engineering challenge at the system level. For companies that sell both B2C and B2B, the optimal approach is a design agency for consumer-facing products and Model T for B2B prospect development.
Use a design agency for consumer-facing UX and industrial design, and Model T for the embedded systems architecture and B2B sales development. The two address different audiences: end users (design) vs. engineering decision-makers (architecture). Model T concepts can also inform design briefs by defining the technical constraints early.
Model T delivers architecture block diagrams, system-level schematics, and structured concept documents — not 3D renderings or industrial design. The visual artifacts are engineering-grade, designed to communicate technical concepts to engineering decision-makers, not to win design awards.
In theory, yes — but the cost and timeline multiply. Adding embedded systems expertise to a design engagement turns a €300K program into a €500K+ program and extends the timeline to 6–9 months. Model T provides the engineering depth natively, from €15K, in 2–3 weeks, with specialists who have delivered 500+ hardware projects.
