A product partner that validates, builds and helps you sell – long after launch

We don't just write code. We find out whether the idea has a market, design it, build it, ship it, then help you win customers with measured ads and SEO. One team, one owner for the whole journey.

Every product starts with a dream, but it often stalls because...

Months go into building something nobody turns out to need

We validate before coding: interviews and a clickable prototype with real users

The finished product brings no customers, because nobody planned measurement and marketing

We stay after launch: measurement, ads and customer acquisition, if you want it

Developers disappear or go on "eternal vacation"

In the client portal you always see where things stand: milestones, documents and the proposal in one place

AI-generated code works at first, then becomes unmaintainable and breaks under real load

Automated tests and code review on every change, plus 1 year of bug fixes

Our Solution

Each of these has a fixed step in our process – refined over 60+ projects, from validation to growth.

How we work

AI writes code. An amateur ships something. We build products – and help you sell them.

From checking the idea to your first paying customers – human care at AI speed.

Already built something yourself – maybe on our Vibe Coding platform? If it works, we take it from there: we review it, harden it and build it for production.

01

Checking the idea

We find out who needs the product and why: we talk to future users, look at competitors and test interest with a small ad – before you spend on development.

What most skip: decisions from data, not gut feeling
02

Detailed plan

We write down exactly what goes into the first version and what can wait – with a timeline and milestones.

What most skip: no surprises, no hidden costs
03

Design, tried out

Custom design that fits your brand. Before we build, real users try the clickable design, so anything unclear surfaces in time.

What most skip: a tried-out experience, not a template
04

Development

Fast progress with AI assistance and continuous automated checks, so everything works as it should – for everyone.

What most skip: AI speed, human engineering quality
05

Demos & reviews

We regularly show where we are and review it together. Before go-live we test everything thoroughly, privacy settings included.

What most skip: you're part of the team
06

Launch

Full App Store & Google Play setup, store assets (description, screenshots, icon) uploaded, submission and approval handled.

What most skip: we handle the store paperwork
07

Winning customers

We set up tracking, launch Google and Facebook ads, and make sure Google and ChatGPT can find your product.

What most skip: not just done – in demand
08

Measuring & improving

We watch how people use the product, catch errors early and keep improving it based on the data.

What most skip: launch is the start, not the end

Optional: monthly partnership after launch

Not required – the project is complete without them, warranty included. If you like, we can continue monthly after launch: either retainer can be chosen on its own.

Development retainer

Optional

Continuous development, maintenance and a weekly call – with the same team that built the product.

Growth retainer

Optional

Ads management, visibility in Google and ChatGPT, and more leads from your existing traffic – with a monthly report, no content production. The ad budget is paid separately and the accounts stay yours.

The privacy check is a technical review, not legal advice.

1-year bug-fix guarantee · milestone-based billing

  • 100% Bug Fix Guarantee

    We don't just promise - we deliver! Free bug fixes for one year after launch - and with most clients we step into year two from here.

  • Direct Communication

    Quick and Continuous responses using dedicated Slack channel

  • 6+ years in product development

    International collaborations, 95% client retention - we work with most of our clients for several years.

Common Questions

FAQ

We've collected some frequently asked questions to help you find your way. If you can't find the answer to your question, feel free to contact us!

  • We start with a free consultation to discuss your goals and project needs. Next, we prepare an initial cost estimate to give you a clear idea of the expected budget. If that fits, we schedule another in-person or online meeting to fine-tune the details, which we then document and finalize within a few days. This leads to the final proposal, a quick contract signing, and the start of the UI design and development phase.

  • No, we never ask for advance payments. You only pay after each development phase is delivered and accepted. This ensures reliability and minimizes risks for both parties.

  • After each development cycle, our expert testers rigorously evaluate the product through both development and acceptance tests. Then, it's your turn. We present our progress for your review, taking your feedback to heart as we refine our focus for the next features. This collaborative approach ensures that the final product is not just exceptional, but also perfectly aligned with your vision.

  • We provide access to the software tools we use, allowing you to monitor the progress of your project in real-time. For graphic work, we utilize Figma, where you can see the ongoing design developments. For tracking the project and development progress, we employ Jira, enabling you to keep a close eye on every stage of the project.

  • Absolutely! We're here to support you throughout the entire planning process and with all administrative tasks. Our team is equipped to help with comprehensive planning, setting up everything you need for your project. We have developed detailed documentation for many tasks, ensuring you're well-supported and informed at every step.

  • Choosing an agency like ours offers a multitude of benefits compared to hiring a freelancer. We provide a comprehensive suite of services in-house, including development, graphic design, and ongoing maintenance. This integrated approach ensures consistency and quality across your project. Moreover, our team is always available, offering you reliability and accessibility that's hard to match. With us, you're not just hiring a professional; you're gaining a dedicated partner committed to your success.

  • We Hope Your App Exceeds Your Wildest Dreams! Beyond delivering a top-notch final product, we also offer ongoing technical support and maintenance to keep your app running smoothly. If you prefer to handle maintenance yourself, you'll have full access to all the technical data you need. But remember, we're always just a call away if you need any assistance.
