SHORT ANSWER

Wavect builds custom software for validated products: MVPs, web and mobile apps, AI products, QA, technical consulting, and full project delivery. We work best when the product question and the engineering question are connected. Every build starts with discovery, ships in weekly reviewable increments, and ends with documentation, tests, observability, and handover.

Best for

  • Founder-led MVPs
  • Validated product builds
  • AI-heavy SaaS
  • Software rescue and vibe-coded prototype hardening
  • QA for production launches
  • Technical product decisions before hiring a CTO

Not for

  • Brochure websites
  • Cheapest hourly staffing
  • Pure legacy maintenance
  • Teams that only need anonymous extra hands

Pick your engagement model

MVP & PoC Development

Build only what you need to hit the next milestone. First client, first investor, or validated idea.

MVP Development

Complete Project Development

Done for you: concept, build, and project management. No headache, no handoff gaps.

Extended Team

We can augment teams when the work still needs senior judgement. We are not the right fit for raw headcount or lowest-cost ticket execution. Fixed weekly retainer, cancel anytime.

Software Quality Assurance

While AI turns coders into copy-pasters, our QA service keeps your software (and reputation) from breaking.

Technical Consulting

Pick the right stack, avoid the expensive ones to hire for, and skip the tech you don't actually need.

Need leadership, not delivery?

Fractional Co-Founder, CTO, CPO, and CTPO live under Fractional Leadership: senior product and engineering judgement without a full-time hire.

BEFORE YOU APPLY

Who our development retainer is not for.

Below the line we'll either route you to the right service or wave you off. Both are wins.

  1. You want hourly billing or weekly timesheets.

    We don't track hours. Two ways we work instead: fixed pricing against a signed scope, or a weekly retainer. Cancel any week, last week refunded if we didn't blow you away. If procurement insists on timesheets, we're structurally the wrong shop.

  2. You don't have a product owner on your side.

    Someone has to decide. "We'll figure it out together" is not a plan, it's a delay. If you need the product thinking too, that's a different engagement.

    Better fit Fractional Co-Founder

  3. You need pure legacy maintenance with no new build.

    We ship new things. If what you actually need is someone to keep a live product safe and stable, our QA partnership covers that. We find what breaks, and we fix it.

    Better fit Software Quality Assurance

  4. Your stack is COBOL, mainframe, SAP customisations, or niche embedded firmware.

    We're heavy on web, mobile, cloud-native, AI, and blockchain. The rest is not our craft.

A clean no costs us a call. A messy yes costs you a quarter. We say no early.

Long-term Partnership

We win when you win. That's the alignment.

THE NO-BULLSHIT GUARANTEE

If we don't blow you away, you don't pay for the week. That's the whole deal.

01.

Cancel any week.

No notice period, no exit fee, no questions.

02.

Refund the last week.

If we didn't blow you away, you don't pay for it. It's in the contract.

03.

No hours tracked.

We work to exceed expectations, not to fill timesheets.

WHY THIS WORKS

We don't sell time. We sell outcomes.

Most agencies sell hours. The longer they stay, the more they earn. The incentives are broken.

Our deal is simpler: every week, we have to earn the next one.

If we don't blow you away, you don't pay for that week. No invoices to dispute, no hours to audit, no calls to escalate.

And if your expectations are detached from reality, we walk too. We work with operators, not lottery winners.

Walking out is not walking away. Anything we built ships documented, version-controlled, and ready for handover. No client is left holding a broken product.

That's why this works. We both have skin in the game.
The Wavect Team

These rules are written into every contract. Weekly retainers (Fractional Co-Founder, Software QA, Development Retainer): cancel any week, refund the last, no hours tracked. Fixed-price projects (Discovery, milestone-based Development): signed statement of work (Werkvertrag), fixed scope and deadline, contractually bound to deliver. Two mechanisms, one promise — we earn what we get paid.

Amazingly efficient, professional, and excellent work. I recently worked with Kevin and his team on a large project. I plan on using him again and highly recommend his services.

Working with Kevin is a real pleasure. He is curious in understanding challenges and at the same time very intrinsically ambitioned in finding the best solution. On top of his undisputed IT-competence his honest and disarming open mind leads to very inspiring relationships. What I value very much is his personal humility towards people. Kevin is a highly recommendable Software-Engineer and a good person who makes an impact.

FAQs

Everything you need to know about our development process

End any week, with one message. No notice period, no exit interview, no fine print. We invoice weekly, so the most you’re ever committed to is the current week.
It’s in your contract: tell us, and we refund that week. No questions, no invoices to dispute, no calls to escalate. The only rule: refunds apply to the most recent week.
Because hours are the wrong metric. If we’re optimizing for hours billed, we’re not optimizing for your outcome. The deal is simpler: every week, we earn the next one. If we don’t, you don’t pay. We’re free to spend zero hours or sixty. What matters is whether you’re blown away.
We work with operators, not lottery winners. If a request would require breaking physics, the law, or a third party’s systems, we say so, and if we can’t align, we walk. The guarantee is mutual: you can fire us any week; we can also fire ourselves.
Yes. Wavect is an Austrian software studio based in Tyrol, building custom software for startups and scale-ups across Austria and the EU. We work remote-first with founders in Innsbruck, Vienna, Linz, Graz, and beyond. You pick the engagement model: a signed fixed scope, or a weekly retainer you can cancel any week.
MVP development is our core. We start with a Discovery Phase so the first line of code solves the right problem, then ship in focused increments you can see every week. For honest cost bands by tier, see how much an AI MVP costs in Austria in 2026.
Yes. We sign a Werkvertrag against a defined scope of work and are legally bound to deliver it. Fixed price means the number does not move unless the scope does. If you would rather not lock scope up front, the weekly retainer is the flexible alternative. We break down the trade-offs in Werkvertrag vs time and material for Austrian SaaS.
We use a milestone-driven approach with constant feedback loops. Every 1-2 weeks, you see working software that you can interact with. We start with detailed wireframes and prototypes before writing any code, and you approve each major feature before we build it. Plus, our team includes Product Managers who translate business needs into technical requirements preventing the common disconnect between what you asked for and what gets built.
Requirements always change, that’s reality. We plan for it. Our agile methodology includes change management protocols: we assess the impact of changes on timeline and budget, reprioritize features with you, and adjust sprints accordingly. Small changes (up to 20% of sprint scope) are typically absorbed without additional cost. Larger changes go through a formal change request process with transparent pricing.
This is actually our sweet spot. We start with a Discovery Phase where we conduct stakeholder interviews, analyze your business processes, research your target users, and study competitor solutions. We then create user journey maps, feature prioritization matrices, and technical architecture proposals. You get a clear roadmap before any development starts, usually saving you months of building the wrong thing.
We’re very flexible. We can augment teams when the work still needs senior judgement. We are not the right fit for raw headcount or lowest-cost ticket execution. We lead specific modules while your team handles others, provide technical mentorship to junior developers, or take full ownership of the project. We use your existing tools, coding standards, and workflows. Your team won’t feel like we’re outsiders, we become an extension of your development capacity.
We use fixed-scope sprints with clear deliverables and acceptance criteria. Every feature is estimated upfront with buffer time included. Weekly reviews ensure we’re on track before small issues become big problems. For larger projects, we break them into phases with separate budgets, you can stop after any phase if priorities change. All additional work requires written approval with cost estimates. We also offer agile fixed-price engagements: scope locked per sprint, no budget surprises.
All our projects include comprehensive testing. We perform unit testing, integration testing, and user acceptance testing before delivery. We also provide detailed documentation and training so your team can maintain the system. Critical bugs are addressed within 24 hours, non-critical within 5 business days.
Technology selection is based on your specific needs, not our preferences. We consider: your existing infrastructure and team skills, long-term maintenance requirements, performance and scalability needs, budget constraints for hosting and licensing, timeline requirements, and hiring market for future developers. We present options with pros/cons and costs, then decide together. We avoid trendy technologies unless they solve specific problems.
You get complete transparency. We provide: weekly sprint reviews with demos, real-time access to project boards (Jira), progress reports, and direct access to developers. You can see exactly what’s being worked on, by whom, and current status. No black box development, you’re involved as much or as little as you want to be.
Testing: unit and integration coverage on every PR with Jest, Vitest, or pytest depending on language. End-to-end with Playwright for web, Maestro or Detox for mobile. Static analysis: ESLint, biome, mypy. Observability: Sentry for errors, OpenTelemetry traces piped to Datadog, Grafana Cloud, or Honeycomb depending on your stack. Logs structured (JSON) from day one. Uptime monitoring with Better Stack or Uptime Kuma. If you’re not getting paged when the app breaks, we didn’t finish the job.
