Do any of thesesound familiar?

  • Design costs grow with every sprint.
  • You are building without a design process.
  • Design rework pushes your launch back.
  • Design and development speak different languages.
  • Every team designs its own way.
  • We can't measure whether the design works.
  • Product launched but adoption remains flat.
  • Redesigns stall without a clear direction.
  • You design without user research.
  • Whoever talks loudest sets the priorities.
  • The MVP shipped, but nobody knows what's next.
  • The design only looks good in Figma.

What is Product Design?

Product Design at Startup House is the end-to-end design process for digital products. We cover user research, UX architecture, UI design, prototyping, and developer handoff. You work with one team from the first research session to the final production-ready file.

We do not separate strategy from execution. Research informs every design decision. Every screen connects back to a user need and a business goal. The result is a product your users understand immediately and your engineers build without guesswork.

Our process & deliverables

  1. 01

    Discovery

    We start every project grounded in real data. We audit your existing product, research your users, and map the competitive landscape, so every design decision that follows has a clear rationale.

    • UX AUDIT OF THE CURRENT SOLUTION
    • COMPETITIVE BENCHMARKING AND TREND ANALYSIS
    • IN-DEPTH USER INTERVIEWS
    • PERSONAS AND CUSTOMER JOURNEY MAPS
  2. 02

    Envision

    We run a co-creation workshop with your team to turn research into direction. We review findings together, identify priorities, and align on a clear product vision before any design work begins.

    • REVIEWED AND PRIORITIZED RESEARCH INSIGHTS
    • DEFINED PRODUCT VISION AND KEY USER PATHS
    • INITIAL PRODUCT BACKLOG AND ROADMAP
  3. 03

    Design

    We design high-fidelity interfaces that reflect your product's final appearance — visual style, interactions, and micro-animations. Everything is built on a reusable component library, tested with real users, and handed off development-ready.

    • HI-FIDELITY SCREEN DESIGNS
    • CLICKABLE PROTOTYPE
    • COMPREHENSIVE UI KIT (COMPONENT LIBRARY)
    • POST-PROJECT DEVELOPMENT SUPPORT
  4. 04

    Testing & delivery

    We test the prototype with users, make the fixes and hand the design over to developers. During the build we run design QA, so the finished app matches the design.

    • USER TESTING
    • POST-TEST FIXES
    • DESIGN QA
    • SUPPORT FOR THE DEVELOPMENT TEAM

How we use AI in design

Faster iteration. More paths tested. Every decision still made by a human.

We generate and compare multiple design directions in Figma before committing to one.

What you gain beyond better-looking screens.

Faster Engineering Delivery

A component library reduces the time developers spend recreating UI elements. Your team ships new features without starting from scratch every sprint.

Higher Conversion and Retention

Visually consistent, intuitive interfaces reduce cognitive load. Users complete key actions more often and return more frequently.

Brand Integrity at Scale

Your product reflects the same visual identity across web, mobile, and every touchpoint. Users recognize your brand without reading a single word.

Reduced Design Debt

A documented design system prevents visual inconsistency from accumulating over time. Onboarding new designers or developers takes days, not weeks.

Accessibility Built In

WCAG compliance is integrated into components from the start, not retrofitted later. Your product meets regulatory requirements (including the European Accessibility Act) without a separate accessibility audit cycle.

Outpace Competitors Visually

Enterprise buyers and end users compare your product to the best interfaces they use every day. A polished, consistent UI signals reliability and positions you ahead of alternatives that look unfinished.

From visual chaos to a scalable design system.

Product Design is not about making things look good. It is about making the right decisions in the right order. When research drives structure, and structure drives visuals, you end up with a product that performs, not just one that looks like it should.

Frequently asked questions

Product Design covers the full process: research, experience design, visual design, and handoff. UX Design focuses on structure and flows. UI Design focuses on the visual language and component system. When you choose Product Design, you get all three handled by one team with a single source of truth.

Yes. Development without a defined design process leads to structural rework, inconsistent interfaces, and misaligned user journeys. A Product Design engagement gives your engineers clear specifications before a single line of code is written.

Timelines depend on product scope and complexity. A focused engagement for a core product or feature set typically runs 8 to 12 weeks. Full product design for a new digital product runs 12 to 20 weeks.

You receive a research report, user flow maps, wireframes, a component library, annotated screen designs, a design system, an interactive prototype, and a developer-ready Figma handoff. Every deliverable is documented and ready for your engineering team.

Both. For existing products, we start with a design audit to identify what is working and what is not. We then redesign the areas with the highest user impact, rather than rebuilding everything from scratch.

Your product and engineering leads join key workshops at each stage. We align on direction before moving forward. You review and approve deliverables at every milestone. There are no surprises at handoff.

We align on metrics before the project starts. Typically these include task completion rates, time on task, conversion rates, and reduction in support volume. We design to those outcomes, not to aesthetics alone.
