Working with Wavect in Graz
The Styrian Business Development Agency describes Styria as Austria’s second-strongest startup region and highlights deep tech, academic spin-offs, industrial technology, production, hardware, energy, mobility, life sciences, and software. That is a useful description of the environment, not a claim that Wavect has worked with every part of it.
The CTO problem in this environment is often the boundary between technical possibility and production responsibility. A prototype can be impressive and still lack release ownership, security, observability, supplier control, or a credible path from one pilot to a maintainable product.
We enter at that boundary. We do not replace domain scientists or engineers. We own the technical decisions that cut across them and make the trade-offs explicit.
Two Graz situations where a fractional CTO earns the title
Deep technology needs technical leadership, but not every team needs that leader full-time yet.
Hardware and software roadmaps keep breaking each other
The first 30 days on a Graz deep-tech or software product
We start by separating research risk from engineering risk.
- Draw the production boundaryDocument what is proven, what is experimental, which components are supplied, and which failures would stop a pilot or customer rollout.
- Choose the next technical evidencePrioritize architecture, reliability, security, performance, and integration work against the next commercial milestone.
- Put ownership on every interfaceAssign decisions across internal engineers, research partners, suppliers, and vendors so integration risk stops belonging to everyone and therefore nobody.

We use these sources for local context. They do not imply a partnership, endorsement, office, or client relationship.

Engagement tiers and transparent pricing
Four ways to start. Each one has a clear scope and a clear cancellation policy. No hours tracked, no surprise invoices.
CTO-on-Call
Async architecture review, hiring panels, tech decisions on demand.
4 to 8 hours per month
Embedded Fractional CTO
Lead the engineering org. Roadmap, hiring, vendor management, production accountability.
1 to 2 days per week
Tech Due Diligence
Fixed-price diligence for fundraising or M&A. Architecture, code, team assessment, investor-ready report.
1 to 3 weeks, fixed
Discovery + Roadmap
Two to three week deep-dive into a single product or transformation. Architecture, milestone plan, fixed-price build offer.

Fixed-price engagements are signed SoW (Werkvertrag). Wavect is legally bound on scope and deliverables. Retainers cancel weekly with no notice.
// 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.

What clients say
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!
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.
Excellent work. The collaboration was very pleasant and you always had the feeling of being in good and capable hands.
