Custom software for small and mid-sized businesses, for a monthly fee

Off-the-shelf software is rigid. Custom development is expensive. We give you the best of both.

You get a system tailored exactly to your business, and you pay for it like a subscription. When something changes on your side, the system follows, because ongoing development is included in the monthly fee. Set-up can even be free.

No commitment, and no finished plan needed.

AI workspace

Like hiring a colleague who never gets tired and never forgets a thing.

It's how our own company runs: our workspace, Nexus, reads the email, drafts the proposals and contract reviews, and runs our engineering too, every day, for real.

  1. 01

    It arrives

    Email, invoices, contracts, bank statements, just like today.

  2. 02

    AI prepares it

    Extracts the task, matches, summarises and drafts the reply.

  3. 03

    You approve

    One click. Nothing goes out without you knowing.

  4. 04

    Done, filed

    In accounting, CRM or your task list, logged.

A source behind every answer

It shows which contract, email or note it worked from, so you can check it with one click.

Every decision on record

Meetings turn into a decision log in your own words, searchable any time.

Everything in one window

Email, documents, tasks and knowledge on one screen. No jumping between five apps.

Just say it

No typing needed: tell it what you want, and it writes it down.

Every cent visible

You see what each step cost. No surprises on the monthly bill.

Personal data protected

Bank account numbers, phone numbers and email addresses are redacted before anything enters the knowledge base.

Nexus · company workspace

What did we commit to Minta Kft. on delivery time?

Nexus

Under section 4.2 of the framework agreement, we deliver within 10 working days of the order. In the email exchange of 14 August this was changed to 15 working days, but the amendment hasn't been signed yet.

We'll build it for any of your workflows.

Wherever there's lots of email, documents and recurring decisions, AI gives you back days every month.

Let's look at mine

Accounting

Invoices that file themselves

From email and billing systems, matched and ready for bookkeeping.

Customer service

Email, sorted

Topic, urgency, owner, and the draft reply is ready too.

Sales

Proposals in minutes

From your templates, based on your past proposals and prices.

Management

Always know where things stand

Open issues, blockers, next steps, summarised by morning.

Local AI

If your data can't leave the company, we run the AI on your own hardware.

It works without internet and sends nothing out. Where it's strongest on-premises:

  • Invoice data extraction, even from scans
  • Questions answered from your internal documents
  • Meeting minutes from audio recordings

How we work

Four steps, and it's up and running.

No months of planning. From the first conversation to go-live, you always know what comes next.

    Informal
  2. 2

    Proposal

    In writing: what we'll build, by when, what the set-up and the monthly fee are. For big systems we start with a quick first step that's useful on its own.

    Clear numbers

    Development

    Every two weeks you try it and decide where we go next. No surprises at the very end.

    Live demos

    Go-live and operations

    We launch it, train your team, and from then on we run it.

    As a service

Why us

  • Direct contact

    You deal directly with whoever builds your system. No account managers, no phone chains.

  • Lightning pace

    We build on our own AI workspace: what takes months elsewhere takes weeks here.

  • At home in finance

    NAV, VAT, bank statements, bookkeeping. No need to explain how a Hungarian company works.

  • Bulletproof code

    Every change goes through automated checks, so your users aren't the ones who find the bugs.

  • Your data stays yours

    Whatever you put into the system is used only for what you've allowed.

  • All in one hand

    Whoever builds it also runs it. If something is wrong, you never have to figure out whom to ask.

Working together

Three ways in, one goal: less manual work

Start small, or go straight for the full system? Your call.

Our pick

As a service (SaaS)

A turnkey system you never have to look after. No servers, no IT staff needed.

  • A fee that follows your usage
  • Updates, backups and development included

Monthly fee

AI pilot for one workflow

One workflow, one measurable goal. In a few weeks you see in numbers how much time it gives back, and then you decide.

  • Low risk, fast results
  • If it works, it keeps running as a service

2–4 weeks

Integration and takeover

We connect your systems, or take the one you have into our care, then run it for a monthly fee.

  • A clear plan before we touch anything
  • Switch-over without downtime

FAQ

What most people ask

Can't find your question? Write to us →

You develop with AI. Won't that make the software rushed and buggy?

Quite the opposite. Whoever builds your software here has been developing software for two decades and knows exactly what AI does well and where a developer has to take over. Here AI is the tool, not the craftsman: code it writes is reviewed by a developer before it goes live.

How much does it cost?

Less than you'd think. We can do the set-up for free, and afterwards you pay a monthly fee that follows how much work the system does for you.

How long until it works?

The first version you can try is in your hands within 1–2 weeks, and from there we keep refining it until it's exactly what you pictured.

Where does our data go when we use AI?

Wherever you allow. It doesn't even have to leave your office, because the AI can run on your own machine. If we work in the cloud, where the data is stored and which AI provider we use is set out in the contract, before anything starts.

Do we buy the system or rent it?

You rent it, as a service. The system is our problem. You just enjoy the benefits.

Our developer left. Can you take over the system?

Yes, it's one of our favourite jobs. We get to know it in a few days, then it's our responsibility.

What technology do you use?

Microsoft .NET, SQL Server and Azure, the long-term supported foundation big companies rely on. We build the AI on top.

Do you work with companies outside Hungary?

Yes. We work remotely and in writing, and we're a natural fit for international companies operating in Hungary that need local invoicing, banking and accounting sorted.
