CODING.

FROM IDEA TO PRODUCT.

Software development is entering a new phase. AI is no longer just a tool for developers — it is becoming part of the development team.

At Krojač we use Vibe Coding, generative artificial intelligence and AI-assisted development to turn ideas into working digital products faster than a classic development process allowed.

Idea → prototype → development → testing → product

Definition

PROGRAMMING IS NOT WHAT IT WAS.

Vibe coding is a new approach to building software in which artificial intelligence is used as an active participant in the development process, not only as help with writing individual lines of code.

AI can help with understanding requirements, writing code, creating components, finding bugs, refactoring and iterating on the product.

That does not mean the developer is gone. The role changes.

The greatest value is no longer only in how fast someone can write code, but in how well they understand the problem, the product, the user, the architecture and the business goal.

Process

FROM THE FIRST PROMPT TO A WORKING PRODUCT.

01

Idea

We start from the problem that needs solving. We define the user, the functionality, the business goal and what actually needs to be built.

02

Prototype

We use AI to quickly explore different solutions, UX concepts and features. We do not spend months planning a product nobody may use.

03

AI development

Through Vibe Coding and AI-assisted development we build real software. Modern AI tools are part of our everyday process, including Claude, ChatGPT and other specialised coding tools.

04

Testing

AI speeds up testing, finding problems and iterating. Every new version can be checked, fixed and improved faster.

05

Product

The goal is not a demo. The goal is a working product that can reach real users.

The economics of development

FASTER DEVELOPMENT IS NOT THE ONLY CHANGE.

AI changes the economics of building software. For certain products it is now possible to build a working prototype in days or hours instead of weeks or months.

But speed alone is not enough. A bad idea built ten times faster is still a bad idea.

That is why Vibe Coding at Krojač is not just “talking to an AI”. It is a combination of product thinking, technology experience and AI development.

Fractional CTO & AI Strategy

It changes how companies

  • test new ideas
  • build MVP products
  • automate internal processes
  • build web and mobile applications
  • maintain existing software
  • experiment with new business models
  • organise development teams
Accountability

AI WRITES CODE. IT DOES NOT MAKE EVERY DECISION.

AI can write a large part of the code. But someone has to know:

  • What needs to be built.
  • Why we are building it.
  • How it should be built.
  • Whether the architecture is sound.
  • Whether the product is secure.
  • Whether the user needs it at all.

That is why experience in Fractional CTO work, product development and technology strategy matters just as much as knowing the AI tools.

Who it is for

WHEN YOU NEED TO BUILD SOMETHING NEW.

For companies that want to test a new digital idea.
For startups that want to build an MVP.
For companies that want to automate an internal process.
For existing development teams that want to bring AI into their work.
For companies that have a problem but do not yet know the best technical solution.
For founders who want to go from an idea to a first working product.
Together

FROM STRATEGY TO CODE.

Vibe Coding answers the question: “How fast can we build something?”

Fractional CTO answers a far more important one: “What should we be building at all?”

That is why these two services naturally belong together at Krojač.

AI strategy → technology decision → Vibe Coding → product

Approach

WE DON'T BUILD AI FOR THE SAKE OF AI.

Before we write the first prompt, we ask:

  • What problem are we solving?
  • What is that problem costing the company?
  • Can AI solve it?
  • Does software need to be built at all?
  • How fast can we build a first version?
  • How will we know it worked?

Only then does development begin.

FAQ

FREQUENTLY ASKED QUESTIONS ABOUT VIBE CODING

What is Vibe Coding?
Vibe Coding is an approach to software development in which AI is used as an active part of the programming process, from understanding requirements and generating code to testing and iteration.
Is Vibe Coding the same as AI programming?
Vibe Coding is one approach to AI-assisted development. The broader term AI development covers different ways of using artificial intelligence in building software.
Can we build a complete application with AI?
For many products AI can significantly speed up both the prototype and the working application. A quality product still requires product thinking, UX, architecture, testing, security and human oversight.
Which AI tools do you use?
We use different AI tools depending on the project, including Claude, ChatGPT and AI coding tools. Tools change quickly, so we do not build our process around a single product.
Do you only build new applications?
No. We also use AI on existing software, for automation, refactoring, testing and improving the development process itself.
Can Vibe Coding replace a development team?
AI can dramatically increase developer productivity and change the structure of the team you need, but architecture, product decisions, quality, security and accountability still require expertise.
