And what is currently in the way. You will speak to an engineer, not an account manager, and you will get a straight answer about whether we are the right fit.

What do you need? (optional)

Before you write

Common questions

  • What does PannonRex actually do?

    We are a software engineering company. We build custom web platforms, mobile apps and AI systems, modernise legacy software that cannot be switched off, advise leadership teams on technology strategy, and place senior engineers into client teams.

  • Do you build AI systems, or only advise on them?

    Both, and we prefer to do them together. Advisory without delivery produces plans nobody can execute; delivery without advisory produces features nobody asked for. Most engagements start with an assessment and continue into a scoped build.

  • Where are you based and who do you work with?

    We are based in Budapest, Hungary, and work with clients across Europe, the United States, the Middle East and Australia — from startups through to large enterprises and nonprofits. Our working hours overlap CET, UK and US East Coast business hours.

  • Can you take responsibility for a system end to end?

    Yes. We can define, build, run and support a system under an SLA, or hand it over to your team with documentation and pairing so they own it. Both models are common for us.

  • What happens after I send this?

    A senior engineer reads it — not a sales inbox. You will normally hear back within one business day with either a few clarifying questions or a proposed time to talk.

  • Is the first conversation really free?

    Yes. A first call of thirty to sixty minutes costs nothing and carries no obligation. We use it to work out whether we can genuinely help.

  • Can you sign an NDA before we talk?

    Of course. Send yours and we will review it, or ask and we will send ours. Either way it can be in place before the first call.
