Prototype
A working model or early version of a product used to test ideas, validate concepts, and gather feedback before full development. Prototypes range from simple sketches to functional interactive models.
What is a Prototype?
A prototype is a tangible representation of your product idea—anything from low-fidelity paper sketches to high-fidelity interactive mockups. It bridges the gap between concept and reality, making abstract ideas testable and visible. Prototypes let teams experiment with features, flows, and designs without committing to full development.
Why It Matters
For startups and product teams, prototyping is a risk reducer. Testing assumptions early saves thousands in development costs by catching problems before engineering begins. Prototypes also help you get genuine user feedback, secure investor buy-in, and align your team around a shared vision. Building something tangible forces you to think through details that sketches alone miss.
What to Look For in an Agency
Find agencies experienced in your product type (web, mobile, hardware). Ask about their prototyping fidelity—do they start low and iterate, or jump to high-fidelity? Check if they combine prototyping with user testing to validate assumptions. Look for portfolios showing how prototypes informed final products, not just how polished they looked.

Design Sprint
A time-boxed, structured problem-solving method where cross-functional teams work intensively over 3-5 days to prototype and test solutions for a specific challenge.
Wireframe
A low-fidelity visual blueprint that maps out page structure, content placement, and user flow before design or development begins. Wireframes focus on functionality and layout, not aesthetics.
Usability Testing
Usability testing involves observing real users interacting with your product to identify friction points, confusion, and opportunities for improvement before launch.
User Research
The systematic process of understanding your users' needs, behaviors, and pain points through interviews, observations, and testing. It informs every design decision.
