Software now touches operations or machines
A connected product, data platform, internal tool, or customer portal depends on physical systems and legacy interfaces. Someone must own reliability, security, integration, and the cost of change.

Working with Wavect in Linz
The City of Linz describes its economic transition as “from steel to digital”: established industry, startups, research, and digital companies working in the same region. That makes Linz different from a generic SaaS landing page.
When software touches machines, production data, legacy systems, or physical operations, architecture decisions carry operational consequences. The job is not to add another tool. It is to decide where ownership sits, how systems fail safely, and which interfaces must remain maintainable after the first vendor leaves.
That is the CTO layer we provide. We do not claim a Linz office or automatic industry knowledge. We start with your system, your operators, and the constraints already on the floor.
Two Linz situations where fractional technical leadership fits
The shared problem is a digital product with consequences outside the browser.
An established company has several technology suppliers
Each vendor owns its package, but nobody owns the total system or handover. We create the architecture and decision layer above the contracts.
The first 30 days on a Linz industrial software engagement
Before changing the stack, we map how software failure reaches the operation.
- Trace systems and operational dependenciesMap machines, data flows, integrations, vendors, access, failure modes, and the people who currently keep the system alive.
- Prioritize production riskSeparate real operational and security risk from architecture preferences and vendor sales pressure.
- Create a delivery ownership modelSet interface owners, acceptance evidence, release gates, incident paths, and a handover requirement for every supplier.
For Linz products, who owns what?
The Fractional CTO
owns architecture, engineering, suppliers, and production. The Fractional CPO Linz
owns customer problems, prioritization, and the product roadmap. Use a Fractional CTPO
when the physical and digital product decisions need one owner.

// 03How the network model works
Three things that make this different from hiring one consultant with one calendar.
You hire two founders, not one consultant.
Kevin and Christof are on every engagement. One is your product and CTO interface, the other is the senior engineer in the room. No account-manager handoff, no junior on the call after week three.
The bench scales when the work does.
15+ specialists we have shipped production work with. Security, zero-knowledge, mobile, ML, IoT. They plug in under the Wavect SoW. One contract, one invoice. We stay accountable for the outcome.
You stay in control of the contract.
Werkvertrag for fixed-price builds (signed scope, legally bound). Retainer for ongoing work (cancel any week). No hour tracking. No scope-creep invoices. The price you sign is the price you pay.
Who is in the room
Two managing directors. Both technical. Both on every engagement.
Kevin Riedl
Managing Director, Operations and Product
- Engineer since 13: TypeScript, C#, Rust, still in the pull requests.

Managing Director, Software

What clients say
LinkedIn
If you're thinking about digitization of your company, tokenization, coding... you name it, I'd strongly recommend to get in touch with Kevin. His knowledge in the field is unparalleled and working with him a sheer pleasure as he is a super nice guy, strategic thinker and proactively hard worker. Thanks for your brilliant work Kev!
LinkedIn
I got to know Kevin around 1 year ago and have been working together with him since then. His vast knowledge in tech and programming combined with his business acumen makes him the go-to person for me in regards to any tech-related topics. Regardless if it is a project in the field of blockchain, IoT, or any other software development domain, I can recommend reaching out to Kevin to benefit from his tech know-how and a business relationship based on trust and customer centricity.
