UX/UI Redesign for Software Service Solution Company

5.0 Sep 15, 2022

Our speed has increased by 25% thanks to Infinum’s work. They’ve delivered the first version of the redesign, but they’re going to make some additional updates after we’ve taken a few months to gather feedback. One of the best results is that there haven’t been too many changes for the users. It’s always difficult for users to switch from one design flow to the other, but their feedback has been that, while the refresh is powerful, the solution still feels familiar to them. Additionally, Infinum definitely reduced the number clicks needed for our users to take actions. They’ve hit all our metrics.

Our new site instantly brought significant increases when compared to the same quarter in the previous year: +106% in sessions, +73% in page views, and +27% in museum visitors. Infinum came up with the idea of highlighting breakups on the world map in the first or second workshop we held, which I found fascinating. We are planning to develop a web shop with Infinum — even though they are expensive from a Croatian point of view, the results are worth the money.

Look for Verified Providers

Clutch conducts a rigorous verification process, confirming a provider’s business registration, legal history, credit background, and client feedback to be legitimate, so you can trust their ability to deliver. Learn more

Hire with confidence

Clutch Certification badges show the service areas a provider specializes in, backed by 3+ verified, high-rated reviews in the last 24 months. Learn more

Why Trust Clutch

At Clutch, we believe trust is the foundation of every business relationship. Our mission is to help buyers make confident, data-backed decisions informed by real client experiences.

Every review on Clutch undergoes a rigorous, human-led verification process to make sure it’s valid. Our team of specialists confirms the identity of each reviewer, ensures the project is legitimate, and only publishes reviews that meet our strict criteria.

Verification doesn’t stop at the point of publication. Our Trust & Safety team routinely audits older reviews against our guidelines. When reviews fall short of our standards, we remove them.

We evaluate service providers using a structured methodology that combines:

In-depth client interviews and ratings
Comprehensive project details
Market presence
Portfolio examples and industry recognition

This data powers tools like the Leaders Matrix, which helps you compare agencies directly. Our research team curates rankings by weighing verified reviews most heavily, so the most trusted and experienced providers rise to the top.

Using this unique combination of verified client feedback and provider-supplied insights, Clutch distills the most important details into clear, digestible summaries so you have everything you need to make confident, informed decisions quickly.

We take fraud seriously. Providers who violate our guidelines may face lower rankings, restricted visibility, or removal from the platform altogether.

Clutch’s commitment to transparency is ongoing. We’re constantly refining our systems to protect the integrity of reviews and support you in finding the right agency.
