Business Systems & Custom Software · Vienna

The systems your business runs on, built and kept running.

We design, build, and operate critical infrastructure — Debian packaging, DNS platforms, 5G charging systems, and bespoke line-of-business software. Senior engineers only, no bench, no hand-offs — and we're still there long after the launch.

Free, no obligation. You talk to an engineer, not a salesperson.

Debian insidersWe package, maintain, and integrate software directly in the distribution.
PowerDNS Certified ConsultantOfficially certified for the full PowerDNS product line.
Trusted by mobile operatorsHands-on 5G BSS and charging work for network operators.
Decades-long supportOur software still runs daily in shops we first served in the DOS era.

Four ways we take a system off your worry list.

Each engagement starts the same way: a short call where you tell us what you're running and what's at stake. From there we scope the work — clearly, in writing.

Commercial Debian Support Debian

Your product, properly in Debian — and staying there. We handle the packaging, the policy work, and the long-term maintenance so what you ship remains installable and supported for years.

  • Packaging and upload of your software into Debian
  • Long-term maintenance across releases
  • Proper integration with the distribution, not a sidecar repo

DNS Infrastructure PowerDNS certified

DNS that stays boring at scale. We design and build DNS platforms and deliver hands-on PowerDNS work — we specialise in the Authoritative Server API and custom backends.

  • Architecture and build-out of DNS infrastructure
  • PowerDNS Authoritative, Recursor, and dnsdist
  • Custom backends and API integrations
Discuss your DNS setup

5G & Telco Systems For operators

We know the 5G stack inside out and work with mobile network operators on the systems the business depends on — from architecture reviews to shipping code.

  • Business Support Systems and charging
  • Architecture, consulting, and hands-on development
  • Integration with the rest of your operator stack

Custom Software Line of business

Bespoke software that runs your daily operations — like Magnolia, our Windows runtime for retail apps. It began as a migration path for our ML3-for-DOS customers and runs Austrian shops to this day.

  • Design and build of line-of-business systems
  • Migration paths for legacy applications
  • Operation and support after go-live

From first call to running system, without surprises.

Step 1

Intro call

Thirty minutes with an engineer. You describe what you're running and where it hurts; we tell you honestly whether we're the right fit.

Step 2

Discovery, together

Real systems are too complex to quote from one call. We work out the requirements with you in a short, defined scoping phase — and it ends with scope, deliverables, and price in writing.

Step 3

Build & keep running

We deliver — and then we stay. Maintenance, operations, and support are part of the offer, and it's the same engineers who pick up the phone in year five.

Built to stay with you.

You've seen how large vendors work: sell the engagement, staff it from the bench, move on once the deal is signed. We built Deduktiva to work the other way around.

Your project is the priority — not one of forty

We're deliberately small and take on few engagements at a time. The engineers you meet on the first call do the work, and nobody gets rotated to the next account mid-project.

We learn your business before we touch your systems

How you earn money, where the risk sits, what a bad week looks like. What we build fits your operation — not a reference architecture with your logo on the title slide.

We stay after go-live

Delivery isn't a handover deck and a goodbye. We maintain, operate, and answer the phone in year five — and because we fix things upstream, in Debian and PowerDNS, you're never stranded on a private fork.

Scoped to what you need, not to what bills most

Written proposals, defined deliverables, and honest advice — including “you don't need this.” When the work is done, we say so. Bringing us in should keep looking like a good decision, year after year.

Tell us what you're running. We'll tell you how to make it solid.

A thirty-minute call is enough to start. It costs nothing, and if we're not the right fit, we'll tell you that too.
