Christof is based locally. Remote-first engineering leadership with optional paid on-site work, published tiers, and clear scope." image: "https://wavect.io/img/general/bak/open_graph_preview.jpg" --- FRACTIONAL CTO · Vienna # Fractional CTO Vienna Christof's home · on-site as surchargeable add-on Remote first, with Christof based in Vienna. Use paid on-site time for the conversations that benefit from a room: board reviews, hiring panels, vendor decisions, and technical due diligence. **Awarded** Top 100 Young Companies in Austria. #36 in 2024, #58 in 2023 (GEWINN magazine). **Shipped** 75+ products, since 2018, across 17 countries. **Languages** Deutsch, English. **Reviews** Google 5.0 stars. Trustpilot 4.5 stars. // 01 ## Working with Wavect in Vienna Vienna gives Wavect one practical advantage: Christof is based here. A board review or hiring panel can happen on-site without turning the retainer into an open-ended presence contract. The city runs an international startup ecosystem. ViennaUP reported more than 14,000 participants from over 90 countries across 65 events in 2026. That says something about the density and international reach of the ecosystem. It does not prove that every Vienna startup is funded, regulated, or ready for a CTO. Our line is simpler: bring us in when technical decisions need one accountable owner. We document the decision, its trade-offs, and who has to deliver it. No innovation theatre, no outsourced title with no authority. // LOCAL FIT ## Two Vienna situations where CTO authority matters The common thread is not company size. It is technical accountability under stakeholder pressure. ### A funded team is approaching diligence or a board decision The product works, but architecture, security, delivery risk, or hiring cannot be explained cleanly. We turn the technical state into decisions and evidence, then own the remediation order. ### Internal engineers and vendors are pulling in different directions A roadmap exists, but nobody has the authority to settle build-versus-buy, integration, platform, or ownership disputes. We make the call and stay accountable for the technical outcome. // FIRST 30 DAYS ## The first 30 days with a Vienna team The output is a functioning decision system, not a slide deck about digital transformation. 1. **Establish the technical truth** - Review code, infrastructure, incidents, vendors, security obligations, delivery promises, and what the board currently believes. 2. **Close the decision backlog** - Resolve the architecture, ownership, hiring, and vendor questions blocking the next milestone. 3. **Make reporting useful** - Introduce a short board-ready risk view, named owners, and a weekly engineering cadence that exposes slippage early. // ROLE CHECK ## Does the Vienna gap sit in product or engineering? Hire the [Fractional CTO](/services/fractional-cto/) when architecture, delivery, hiring, vendors, or production have no owner. Hire the [Fractional CPO Vienna](/services/fractional-cpo-vienna/) when the post-PMF roadmap and discovery cadence are the problem. Use the [Fractional CTPO](/services/fractional-ctpo/) when one person must own both. // SOURCES ## What we use for Vienna context We use these sources for local context. They do not imply a partnership, endorsement, office, or client relationship. - [City of Vienna: ViennaUP 2026](https://presse.wien.gv.at/presse/2026/05/23/tausende-startups-in-wien-rekordandrang-bei-festival-viennaup) Official city report on the scale, international participation, and programme of ViennaUP 2026. // 02 ## 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 FROM €2,500 / month Embedded Fractional CTO Lead the engineering org. Roadmap, hiring, vendor management, production accountability. 1 to 2 days per week FROM €12,000 / month Tech Due Diligence Fixed-price diligence for fundraising or M&A. Architecture, code, team assessment, investor-ready report. 1 to 3 weeks, fixed FROM €8,000 fixed Discovery + Roadmap Two to three week deep-dive into a single product or transformation. Architecture, milestone plan, fixed-price build offer. 2 to 3 weeks, fixed FROM €3,500 fixed Fixed-price engagements are signed SoW (Werkvertrag). Wavect is legally bound on scope and deliverables. Retainers cancel weekly with no notice. // 03 ## How 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. // 04 ## Who is in the room Two managing directors. Both technical. Both on every engagement. ![Kevin Riedl, Managing Director, Operations and Product](/img/team/kevin.webp) Kevin Riedl Managing Director, Operations and Product - Engineer since 13: TypeScript, C#, Rust, still in the pull requests. - Founder-led podcast, 96 episodes with 9-figure founders. - 75+ products shipped across 17 countries.

Christof is based in Vienna; Wavect GmbH is registered in Ampass, Tirol. We do not present a founder’s location as a separate company office. Day-to-day work is remote, and useful on-site sessions are quoted separately. ### Can you join a board or investor technical review in Vienna? Yes, as part of an agreed scope. We can explain architecture, delivery risk, security work, hiring, and the remediation plan. We do not manufacture a clean bill of health. If the evidence is weak, the board gets the weak evidence and a plan to fix it. ## Structured Data ```json { "@context": "https://schema.org", "@graph": [ { "@id": "https://wavect.io/#organization", "@type": [ "Organization", "ProfessionalService", "LocalBusiness" ], "employee": [ { "@id": "https://wavect.io/team/kevin-riedl/#person", "@type": "Person", "jobTitle": "Managing Director", "name": "Kevin Riedl", "url": "https://wavect.io/team/kevin-riedl/", "worksFor": { "@id": "https://wavect.io/#organization", "@type": [ "Organization", "ProfessionalService", "LocalBusiness" ] } }, { "@id": "https://wavect.io/team/christof-jori/#person", "@type": "Person", "jobTitle": "Managing Director", "name": "Christof Jori", "url": "https://wavect.io/team/christof-jori/", "worksFor": { "@id": "https://wavect.io/#organization", "@type": [ "Organization", "ProfessionalService", "LocalBusiness" ] } } ], "founder": [ { "@id": "https://wavect.io/team/kevin-riedl/#person", "@type": "Person", "jobTitle": "Managing Director", "name": "Kevin Riedl", "url": "https://wavect.io/team/kevin-riedl/", "worksFor": { "@id": "https://wavect.io/#organization", "@type": [ "Organization", "ProfessionalService", "LocalBusiness" ] } }, { "@id": "https://wavect.io/team/christof-jori/#person", "@type": "Person", "jobTitle": "Managing Director", "name": "Christof Jori", "url": "https://wavect.io/team/christof-jori/", "worksFor": { "@id": "https://wavect.io/#organization", "@type": [ "Organization", "ProfessionalService", "LocalBusiness" ] } } ], "legalRepresentative": [ { "@id": "https://wavect.io/team/kevin-riedl/#person", "@type": "Person", "jobTitle": "Managing Director", "name": "Kevin Riedl", "url": "https://wavect.io/team/kevin-riedl/", "worksFor": { "@id": "https://wavect.io/#organization", "@type": [ "Organization", "ProfessionalService", "LocalBusiness" ] } }, { "@id": "https://wavect.io/team/christof-jori/#person", "@type": "Person", "jobTitle": "Managing Director", "name": "Christof Jori", "url": "https://wavect.io/team/christof-jori/", "worksFor": { "@id": "https://wavect.io/#organization", "@type": [ "Organization", "ProfessionalService", "LocalBusiness" ] } } ], "name": "Wavect GmbH", "subjectOf": { "@id": "https://wavect.io/verified-claims.json#dataset", "@type": "Dataset", "creator": { "@id": "https://wavect.io/#organization", "@type": [ "Organization", "ProfessionalService", "LocalBusiness" ] }, "description": "A machine-readable registry of quantitative and qualitative claims published by Wavect, with review dates, localized page appearances and public third-party citations where available.", "inLanguage": "en", "isAccessibleForFree": true, "license": "https://creativecommons.org/licenses/by/4.0/", "name": "Wavect verified publication claims", "url": "https://wavect.io/verified-claims.json" }, "url": "https://wavect.io/" }, { "@id": "https://wavect.io/team/kevin-riedl/#person", "@type": "Person", "jobTitle": "Managing Director", "name": "Kevin Riedl", "sameAs": [ "https://www.wikidata.org/wiki/Q139796365", "https://www.linkedin.com/in/wsdt", "https://github.com/wsdt" ], "url": "https://wavect.io/team/kevin-riedl/", "worksFor": { "@id": "https://wavect.io/#organization", "@type": [ "Organization", "ProfessionalService", "LocalBusiness" ] } }, { "@id": "https://wavect.io/team/christof-jori/#person", "@type": "Person", "jobTitle": "Managing Director", "name": "Christof Jori", "sameAs": [ "https://www.wikidata.org/wiki/Q139796367", "https://www.linkedin.com/in/jocr77/", "https://github.com/jo-chris" ], "url": "https://wavect.io/team/christof-jori/", "worksFor": { "@id": "https://wavect.io/#organization", "@type": [ "Organization", "ProfessionalService", "LocalBusiness" ] } }, { "@id": "https://wavect.io/#website", "@type": "WebSite", "inLanguage": [ "en", "de", "es", "zh" ], "name": "Wavect", "potentialAction": { "@type": "SearchAction", "query-input": "required name=search_term_string", "target": { "@type": "EntryPoint", "urlTemplate": "https://wavect.io/search/?q={search_term_string}" } }, "publisher": { "@id": "https://wavect.io/#organization", "@type": [ "Organization", "ProfessionalService", "LocalBusiness" ] }, "url": "https://wavect.io/" } ] } ``` ```json { "@context": "https://schema.org", "@type": "FAQPage", "mainEntity": [ { "@type": "Question", "acceptedAnswer": { "@type": "Answer", "text": "Christof is based in Vienna; Wavect GmbH is registered in Ampass, Tirol.
