The product experience users don't abandon
Product UI/UX design services for B2B SaaS companies struggling with activation or churn. We design products that help users succeed—not just look good in screenshots.
Is Your Product Ux Costing You Users?
Stop watching users struggle through your onboarding
Your product works. The features are there. But users get confused during onboarding, support tickets pile up, and activation rates stay flat. Your sales team says demos are harder than they should be. Churn is creeping up — and your product experience is the reason.
Meanwhile, competitors with fewer features but better UX design are winning users. Your product team is buried in feature requests instead of fixing the core experience. Enterprise buyers test your product once and don't come back.
Your product isn't just functionality — it's the user experience that determines if users activate or churn. In B2B SaaS, a confusing interface costs you activation rates, increases support burden, and makes every sale harder than it needs to be.
Polybox is a product UI/UX design agency for B2B SaaS. We improve onboarding, reduce churn, and increase activation — 25+ SaaS companies and counting.
The process
We audit your current product's user experience, analyze behavior data, interview stakeholders, and review activation metrics.
Low-fidelity wireframes mapping user flows, onboarding sequences, and information architecture. We solve usability problems and optimize task completion before visual design.
High-fidelity UI mockups with full visual design applied. Every screen designed for your key user flows, responsive layouts, and interactive states.
Interactive Figma prototypes, design system documentation, developer handoff specs with assets, and implementation guidelines.
Usability testing with real users, feedback analysis, iteration rounds on critical paths, and final design validation.
Timeline: 6-12 weeks depending on scope. SaaS UX audit projects: 2-3 weeks.

What makes us different
We start with research, not assumptions.
Most designers jump straight to mockups. We start by understanding your users — their goals, pain points, and actual behavior. Every product design decision is backed by data from user research, analytics, and stakeholder insights.
We design for activation and retention, not just beauty.
Pretty interfaces that confuse users are expensive failures. We optimize for the SaaS metrics that matter — activation rates, time-to-value, feature adoption, churn reduction. You get product UX that helps users succeed, which means they stay.
We hand off working systems, not static files.
You don't just get mockups. You get interactive Figma prototypes, design systems with reusable components, and developer handoff documentation that makes implementation smooth. Your engineering team can actually build what we design.

Common questions
Full-time senior product designers take 3-6 months to hire and cost $120K-$180K annually. We give you senior-level expertise on-demand, with research capabilities and no hiring overhead. You get better results faster, and scale up or down as needed.
A UX audit (2-3 weeks) evaluates what's broken and gives you a prioritised fix roadmap. A product redesign (8-16 weeks) implements the solutions — new user flows, UI design, prototyping, usability testing, and developer handoff. Many clients start with the audit, then move to a redesign based on findings.
Start with the Audit. It gives you clarity on what's actually broken and a roadmap for fixing it. Many clients start with an audit, then move to MVP or Custom design based on what we find.
Yes — our MVP Product Design package is built specifically for startups taking a product to market. It includes user research, wireframing, high-fidelity UI, interactive prototyping, and developer handoff. Everything you need to launch with confidence and validate product-market fit.
Our SaaS UX audit includes a screen-by-screen usability teardown, user journey analysis of onboarding and core tasks, stakeholder interviews, competitive benchmarks, and analytics review. You get an executive summary with a prioritised 30/90/180-day fix roadmap and effort estimates for every recommendation.
We map your current onboarding flow against user behavior data — where do users drop off, what confuses them, what steps feel unnecessary. Then we redesign the flow to get users to their first value moment faster, test with real users, and iterate. Onboarding is typically the highest-leverage area for improving activation rates.
Most SaaS churn comes from poor onboarding, confusing navigation, or features users can't find. We identify these friction points through user research and analytics, then redesign the flows that matter most — onboarding sequences, core task paths, and feature discovery. Better UX means users reach value faster, which directly improves retention.
Yes. We integrate into your workflow—joining standups, working in your project management tools, and collaborating directly with PMs and engineers. We're not a black box—we're an extension of your team.
Both. For MVP and Custom packages, we can extend your existing design system or build a new one from scratch. The Audit package includes a design system consistency review if you already have one.
For a SaaS UX Audit: 4-6 hours (kickoff, stakeholder interviews, findings review). For MVP/Custom product design: 8-12 hours (research sessions, design reviews, testing feedback, final handoff). We handle the rest.
Absolutely. Our portfolio includes product UI/UX design work for B2B SaaS across industries, with metrics on activation improvements and churn reduction where clients have shared them.
All packages include 30 days of post-handoff support for questions during implementation. After that, you can work independently or continue with our ongoing design partnership retainer for iteration and new features.
