Product Engineering
Test the idea before
funding the build.
A prototype costs a fraction of a full product build — and answers questions that a specification document cannot. GreaterHeight builds prototypes that are realistic enough to surface genuine user feedback, align stakeholders, and de-risk the investment decisions that follow.
Prototyping Services
Three levels of prototype fidelity
Wireframes & Flow Diagrams
Low-fidelity structural layouts that define information architecture, user journey, and screen flow — fast to produce and easy to iterate on before visual design begins.
Interactive Clickable Prototype
High-fidelity, brand-designed screens in Figma with clickable interactions — realistic enough for user testing sessions and investor demonstrations without any backend code.
Functional Proof of Concept
Working software for the core value proposition — real data, real APIs, real user interactions — built quickly using prototyping-friendly stacks and architecture.
User Testing Facilitation
Structured user testing sessions using the prototype, with moderated interviews, task completion analysis, and findings synthesis into actionable product decisions.
Investor Demo Preparation
Polished prototype and demonstration narrative preparation for fundraising presentations — making the product real enough to validate the investment thesis.
Prototype to Product Handover
When prototyping leads to a full build — which it usually does — we transition seamlessly to the development phase with the learnings fully incorporated.
