You know you need Digital Transformation. But where do you start?

Before you spend on software or AI, VAON looks at the systems you already have with you, points out what to fix first, and lays out a prioritised roadmap. Our CEO is involved from the first call.

5 signs it's time for an outside look at your systems

  • Your legacy system is slow and costs more to maintain every year

  • You can't decide between AI, cloud, or both

  • You've outsourced, but quality is inconsistent

  • You want to pursue DX but have no CTO or in-house tech team

  • You need an independent technical assessment of your system or your current vendor

Not having a CTO isn't a failure. Many mid-sized companies get there with someone technical at the table.

I don't allow a "get it done" mindset. It has to be an "own the product" mindset.

Case study: lock the scope before building

Seminar Navi, Kochi University of Technology

The problem:

  • The university needed an app for its career seminar, connecting companies with students

VAON's proposal:

  • Lock the scope with the university from the start: no student names collected
  • Rule-based suggestions, no generative AI
  • A LINE app (LIFF) + PWA + admin screens

Frequently Asked Questions

It depends on your entry point. If you already have a system, VAON reads the code, interviews the people who run it and measures the current state, then gives you a current-state report and an improvement roadmap. If you have nothing yet, we write the requirements, wireframes and data design. It usually takes 1 to 2 weeks, or 2 to 4 for large projects.

No. You receive every document and are free to stop here. How you may use the documents, including with another team, is set out in the phase contract.

It is a fixed price, quoted after the first call because it depends on the size of your system. The price does not change during the phase.

Yes. For an existing system, VAON reads the source code (with AI assistance when you agree to it), interviews the people who run it and measures the current state. Code shows what a system does but not why, so every point is checked with the business users. We sign an NDA before receiving the code.

The roadmap sets out what to do and in what order, without tying it to a vendor. If an off-the-shelf product is enough, we say so. You can use the documents with any team, under the terms of the contract.
