Business Systems & Custom Software · Vienna
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.
What we do
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.
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.
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.
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.
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.
How we work
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.
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.
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.
Why Deduktiva
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.
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.
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.
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.
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.
Next step
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.
