Working with UPNEXT (formerly SPLX) on the UX analysis of our SYNLAB e-shop was excellent. Their team gave us a detailed, clear analysis that pinpointed specific areas to improve the user experience. Thanks to their expert recommendations we were able to simplify the site's navigation and increase customer satisfaction. We appreciate their professional approach, the speed of delivery, and their ability to bring fresh perspectives to our e-shop's design.
The UPNEXT (formerly SPLX) team does absolutely top-class work and their reliability is second to none. From the very start we were pleasantly surprised by their professional approach, fast communication, and attention to detail. They handled every task precisely and exactly to our requirements. What we value most is their knack for always finding an effective solution. They're true experts in their field and you can tell they love what they do. If you're looking for people you can rely on 100%, UPNEXT is the clear choice!
Communication during the UX analysis with UPNEXT (formerly SPLX) was excellent, and we got genuinely relevant feedback on our website. I appreciate the constructive criticism and professionalism that helped us better understand usability and navigation on our e-shop. Thanks to their expert recommendations we were able to implement our next steps far more effectively.
What I want to praise most is the honesty and constructive criticism you shared with us. It's great to talk to people who genuinely listen, yet immediately grasp the client's context and business, have the experience, and are bold enough to get to the heart of the matter. I'd absolutely recommend working with - and the initial analysis from - UPNEXT (formerly SPLX) to anyone who truly wants to hear, straight up, how to improve their website and their whole customer experience, all tied directly to their brand's specific goals.
A super professional approach from the first conversation and planning of the work all the way through to the consultation itself - which definitely wasn't just skimming the surface. You can tell they genuinely care about understanding both the client and their customers. They asked great questions and brought their own insights and suggestions that weren't creative just for the sake of it, but grounded in facts, data, and experience. Hats off and a big thumbs up!
Ráda doporučím UPNEXT (dříve SPLX) za práci na našem novém webu. Začali jsme od návrhu rozložení, který jsme společně rychle dotáhli do finální podoby. Jejich odbornost a důraz na řešení na míru stojí za pochvalu. UPNEXT doporučím každé firmě, která hledá profesionální web.
- Day 1
Kickoff together
We sit down, align on goals, and agree how we'll work together. No ambiguity going in.
- Within 7 days
A clickable prototype in hand
In the very first week you get a simple clickable prototype. No waiting weeks to see where it's heading.
- Every week
Demos, not reports
Once a week we show you working output and you give feedback on it directly. You follow the whole build live.
- After launch
We don't disappear
After launch we watch the data and keep improving. We're here afterwards too, not just until the invoice clears.
The code and data are yours
Everything we build belongs to you. No lock-in, no dependency - you can take it with you any time.
No surprises
A steady rhythm, a clear agreement, and a budget you know up front. Nothing blindsides you mid-project.
You talk to us directly
You work straight with the people building it, not through an account manager. When you need something, we're right there.
We grow with you
Launch isn't the end. We watch the numbers, tune, and help you scale. We treat your business as our own.
Upnext - a product studio from Prague.
We're a small team of designers and developers. We build websites and products for companies that want to grow - not just have a new site. Every project runs as a product: from strategy through design to data after launch.
