How the studio works
350life is a product design and development studio based in Slovenia, working with startups and enterprises across Europe and the United States on brand, product design, and software development.
Brand, product design, and development stay connected from the first decision to release. We use AI where it improves production work. Direction, judgement, and quality control remain ours.
We work with YC-backed startups, national enterprises, and public institutions across Europe and the United States.
Why 350life exists
350life started before it was a company. Websites and web apps built at home, for free, with a developer in the family. Watching something you made actually work was reward enough.
That part never changed. The studio opened in 2019, and the job has been the same ever since: listen to someone's idea properly, then build it into a product people can use. The industry has rarely mattered. The listening always has.

How we operate
1We move fast, and we own the result
A first release typically ships in four to eight weeks, and a full product build in two to four months. What we ship is ours to stand behind. When something is wrong, fixing it is our job, not a change request.2You will not wait for an answer
We reply the same day. For the whole engagement there is someone reachable who knows your product and can make a decision about it.3We iterate until it is right
Nobody should end up with a product they did not want. Work is shown early and often, so direction can still change while changing it is cheap.4Keep the work connected
Brand, product design, and software development follow one product direction and one scope. Flows carry the states, edge cases, and rules engineering needs, and design systems map cleanly into code.5The industry is not the constraint
Retail investing, national logistics, satellite operations, medical devices, public broadcasting. The product questions rhyme; what changes is who we have to listen to, and how carefully. The same discipline applies to a funded startup's first release and to a national platform.

“350life is an incredible design team. They are thoughtful, strategic, and have an eye for clean and modern design.”
Jonathan ManuzakFounder & CEO, Cashews 
“350life didn't just improve our website. They legitimated our startup. Their UI/UX work was next-level, and they saw onboarding issues before we did.”
Rachelle BrempongCo-founder, Bettershot
“We're really happy with the work. 350life designed our iPhone app, and it looked so good we expanded the project to the Mac app right away. Both have shipped, and the product is getting very good traction. Their designs gave our team a ton to build, but helped us ship a polished product in quick time. We love their work, and we'll be back for more product work.”
Matt RongeCEO, Astropad“350life are a dream to work with. They are insanely fast and thorough. We'd often hand off a loose idea at the end of the day and wake up to a polished solution.”
Tara KappelCo-founder & CPO, RealRoots“As a client, I'm deeply impressed by their exceptional professionalism, creativity, and prompt delivery. Their meticulous attention to detail, innovative ideas, and commitment to deadlines sets them apart from any competition.”
Dejan CenceljLead Engineer, MMC, RTV Slovenija“I got to know the team through a recommendation from one of my clients…I directly commissioned the team for the next company.”
Daniel PannruckerCEO, Lama Partners“We brought 350life in for UI and UX design on a custom software project, and they worked as part of our team from day one. They joined our daily meetings, collaborated directly with our developers, and made sure every design decision could actually be built. The end result was a beautiful, visually captivating interface that our own client was genuinely impressed with. Deliverables always came on time, and they went the extra mile when deadlines demanded it. We will definitely hire them again.”
Romano PravdičCEO, Cloud9“I’m super impressed with the speed of learning new things you have been so casually showing off! I mean every word of it! So impressed with your not being afraid of learning new things. I’ll keep pushing and challenging you to see where you can go. :)”

Nejc ŠkoberneFounder & CEO, Sellestial“The whole 350life team did a great job in building our MVP - from design to launch. We moved extra fast and they helped us implement some of the custom stuff that was needed on top of our Bubble implementation.”

What does 350life do?
350life is a product design and development studio based in Slovenia, working with startups and enterprises across Europe and the United States on brand, product design, and software development. Brand, product design, and development stay connected from the first decision to release, under one scope.
Where is 350life based, and who do you work with?
The studio is based in Slovenia and has been operating since 2019. Clients are YC-backed startups, national enterprises, and public institutions across Europe and the United States, and the work has run from a funded startup's first release to a national platform.
How fast do you ship?
A first release typically ships in four to eight weeks, and a full product build in two to four months. Those are published commitments rather than best cases, and they assume a clear brief: the clock starts when you have explained what you want, not at first contact.
Do you use AI to do the work?
We use AI where it improves production work, and direction, judgement, and quality control remain ours. It is part of why the timelines above are what they are. What we ship is ours to stand behind either way.
Who will actually be working on our product?
Senior people, on the work itself, for the whole engagement. There is someone reachable who knows your product and can make a decision about it, and we reply the same day.
