SHORT ANSWER
Wavect is a custom software development company that builds 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
- Internal tools and systems integration where off-the-shelf software does not fit
- Technical product decisions before hiring a CTO
Not for
- Brochure websites
- Cheapest hourly staffing
- Pure legacy maintenance
- Teams that only need anonymous extra hands
Choose the owner that matches the risk
Ongoing release quality
Use independent QA when a live product needs repeatable testing and release gates.

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.
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.
- Better fit Fractional Co-Founder
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 Software Quality Assurance
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.
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.

Your Journey with Wavect
From idea to paying customers, and the long haul beyond that.
You buy an outcome, not hours. Fixed price where the scope is clear, weekly retainer where it isn't. If a retainer week moves nothing, you get it back.

WHY THIS WORKS
Not our model: Pay by time
Pay for outcomes.
Two ways to work. One reason to deliver.
Fixed prices and weekly retainers. A money-back guarantee built into both.
Tell us the outcome
No hours tracked in either model.
02/ONGOING
Weekly retainers
- Cancel any week.
- Refund the last.
- No hours tracked.
Accountability is the foundation.
Not an add-on. Part of the deal.
That's why this works. We both have skin in the game. How the guarantee works
Money-back guarantees follow the applicable engagement terms. For fixed-price projects, the refund conditions must be included in the signed statement of work. For weekly retainers, the guarantee covers the last week, not the entire engagement.
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.
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.

What clients say
Trustpilot
Delivered all work on time, even under tight deadlines. The perfect balance between professional standards and a collaborative working relationship.
Google
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.
LinkedIn
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 optimize for hours billed, we do not optimize for your outcome. The deal is simpler: every week has a defined result, and we earn the next week by delivering it. You pay for progress against that result, not for a timesheet.
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.
Custom software development means designing and building software for your specific workflows, users, and business model instead of licensing an off-the-shelf product. You own the code, the roadmap, and the data model. It costs more upfront than a subscription, and it is the right call when the software IS your product, or when no standard tool fits how you actually work.
Off-the-shelf wins when your problem is generic: accounting, CRM, email. Custom wins when the software is your product, your competitive edge, or when standard tools force you to bend your process around their assumptions. The honest test: if you’re paying people to work around a tool, you’re already paying for custom, just without owning anything. We break down the full decision in custom software vs off-the-shelf
.
A typical cross-platform MVP with us lands at €25-50k; discovery starts at €3,500 and is deducted from the build. The real driver is scope, not hourly rates. For honest cost bands by project tier, see what software development costs in Austria
.
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. For coverage by state, EU data residency, and Austrian funding like the Forschungsprämie, see software development in Austria
.
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.
Yes. Studios that win build work they cannot staff use us as the engineering team behind their brand, and we do not sell design, branding or strategy, so there is nothing for us to cross-sell into their client relationship. The delivery model is the same one described above; what changes is who the client is. Details and the commitments that make it workable are on For agencies
