Our Interactive Prototype Design Services

From concept validation to investor presentations, we create interactive prototypes that bring your product vision to life.

Clickable Prototype Development

Build fully interactive, clickable prototypes in Figma that simulate real product experiences. Perfect for user testing, stakeholder demos, and validating design decisions before development begins.

Micro-Interaction Design

Design delightful micro-interactions including hover states, loading animations, transitions, and gesture controls that make your product feel polished and professional during demos and testing sessions.

User Flow Prototyping

Create comprehensive user flow prototypes that map complete customer journeys from onboarding to key actions. Identify friction points and optimize paths before investing in development.

High-Fidelity Interactive Mockups

Develop pixel-perfect, interactive mockups with real data, animations, and state changes. Ideal for investor presentations, fundraising decks, and securing strategic partnerships.

Usability Testing Prototypes

Build testable prototypes optimized for gathering user feedback. Includes multiple variants for A/B testing and detailed interaction specifications for research teams.

Developer Handoff Specifications

Create developer-ready prototypes with detailed interaction specs, animation timing, state behaviors, and technical documentation that eliminate ambiguity and accelerate implementation.

Risk-Free Innovation

Validate Ideas Before You Build

Interactive prototypes are your fastest path from concept to confidence. We transform abstract ideas into tangible experiences you can test with real users, present to investors, and hand off to developers with precision. Our prototypes help climate tech and deep tech companies reduce development risk, secure funding faster, and launch products that customers actually want. With turnaround times as fast as 48 hours for iteration cycles, we keep your innovation moving at startup speed.

Frequently Asked Questions

What is interactive prototyping?

Interactive prototyping is the process of creating clickable, navigable mockups that simulate how a final product will look and behave. Unlike static designs, interactive prototypes allow users to click through screens, trigger animations, and experience user flows as if using a real application. These prototypes are essential for user testing, stakeholder presentations, and guiding development teams with precise interaction specifications.
