Who this is for

The first release has one job: prove the product is worth building further

We define the product idea, identify the smallest complete experience that can test it, and state what will wait. Brand, product design, and development run as one engagement. You finish with a released product that can collect real feedback and become the base for what follows.

What you get

  • A working product released to users

    A web, iOS, or Android product that supports the core user flow and can collect meaningful feedback.

  • One scope for brand, design, and development

    The product proposition, identity, interface, and software are planned and delivered against the same release goal.

  • A typical four-to-eight-week first release

    The exact timeline is set in the written scope, with the release boundary and required client decisions made explicit.

  • A base for the next release

    The product is structured so validated features can be extended rather than automatically rebuilt after launch.

How we work, in detail

How it works

  1. Define the core product loop

    We identify the product idea, the core user flow, and the smallest complete scope needed to test it. Deferred features are documented.

  2. Design and build in the same loop

    Core flows, interface states, components, and working software develop together, with decisions tested in implementation early.

  3. Ship to real users

    We prepare the production release for the web, App Store, or Google Play and verify the full core flow before launch.

  4. Learn and decide what's next

    The first release creates evidence for the next decision: strengthen the core, expand the product, or change direction.

Thanks to 350life's work, the app was delivered on time and within budget. User onboarding was quick and painless.

Rok LenardičCEO, Indigo Labs

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

Rok GregoričLead iOS Developer, Benson

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

They are very devoted to what they do and they put all their efforts to understand what you need. Communication is transparent and responsive.

FAQ

How fast can you ship a first release?

A first release typically takes four to eight weeks, and a full product build two to four months. The exact timeline depends on the platforms, integrations, and scope of the core user flow, which we define in the free written scope.

Will the first version be something we can build on, or throwaway code?

Yes. We structure the first release so validated features can become the base for the next version. Any shortcut required by the timeline is documented before it is taken.

Do you handle both design and development?

Yes. An app engagement can cover the product proposition, brand identity, product design, development, and release to the web, App Store, or Google Play.

Do you build web apps, or only mobile?

Both. We design and build web applications as well as native iOS and Android apps, and choose the platforms from the product requirements rather than a fixed stack.

Do you work with US and European startups?

Yes. 350life is based in Slovenia and works with startups across Europe, including Germany and the Benelux, and in the United States. Several clients are YC-backed.

We're not a technical team. Is that a problem?

No. You bring the domain knowledge, audience, and business goal. We translate that into a product scope, interface, technical plan, and shipped first release.
