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

  • Cheapest hourly staffing
  • Teams that only need anonymous extra hands
SPECIALIST PATHS

Choose the owner that matches the risk

Ongoing release quality

Use independent QA when a live product needs repeatable testing and release gates.

See Software Testing and QA

AI-generated prototype hardening

Use Vibe Coding Rescue for a one-time audit and targeted hardening before production.

Vendor handover and stabilization

Use Software Takeover when access, documentation, releases, and continued maintenance need a new owner.

Weekly guarantee First week not worth it? Refunded, no questions.

Fixed-price guarantee Money back for the agreed milestone. No questions asked. The signed scope and deadline still apply.

Optional Fast Lane

Need it sooner? Book a date we have to hit.

Get more agreed delivery into the same week, or the same scope completed sooner, through additional reserved capacity and parallel execution. Testing and acceptance stay the same. Eligible milestones can take about 1/3 to 1/2 of the standard quoted time. Miss the agreed date and we refund 100% of its surcharge.

Illustrative schedule: 30 business days as standard, or 10 to 15 with Fast Lane if the readiness check allows it. Your offer states one exact delivery date.

Date met

You get the agreed scope, tested and accepted, on the Fast Lane date. That date is what the surcharge pays for.

Date missed

100% of the Fast Lane surcharge goes back to you within 10 business days of the missed date. No dissatisfaction claim, no correction cycle first. Delivery continues and all your other rights stay.

  • Same scope, testing and acceptance criteria
  • One exact Fast Lane date, in writing
  • Date missed: 100% of the surcharge back
  • Base price and existing guarantees unchanged

The Fast Lane surcharge is a separate line in your offer, agreed before you book.

Eligibility and full Fast Lane terms

Written down before you book

  1. Standard schedule for the milestone
  2. Booked start date, with everything needed to begin ready
  3. Exact Fast Lane deadline
  4. Deliverables and acceptance criteria
  5. Fast Lane surcharge
  6. Dependencies on your side and on third-party vendors

When Fast Lane is available

We check scope, inputs, dependencies and team capacity before reserving a Fast Lane slot. We agree an earlier date only when the same testing and acceptance fit.

When the date can move

Blocked client or agreed vendor inputs, or a change of scope, can move only the affected delivery date, openly and by agreement. Our staffing or overbooking never moves it.

What Fast Lane never compresses

Required observation windows, security and QA checks, vendor lead times and exploratory research run at their real length. We plan the Fast Lane date around them and never promise to shorten them.

The refund

Miss the agreed Fast Lane date and we refund 100% of its surcharge within 10 business days of that date. No dissatisfaction claim or correction cycle is required. This refund covers the Fast Lane surcharge; the base project fee keeps its existing guarantees. Business days are Monday to Friday, excluding Austrian public holidays (Europe/Vienna).

Everything else stays

Base delivery continues, and your acceptance rights and our existing satisfaction and acceptance guarantees apply unchanged. Fast Lane buys an earlier date, never a lighter finish.

Ask about a Fast Lane date

We check feasibility first, then quote the surcharge with an exact date.

What we actually ship

Our technical core competencies: things we've shipped, not just studied.

Free skills · No API key · No signup

Two free skills for teams shipping production code

We use these prompts on real engagements. QA audits and high-ticket landing pages that close. Drop them into your own AI before you ship.

  1. QA Advisor

    Audits your tests like a senior engineer: OWASP, reliability, scalability, and the mocked-DB tests that quietly pass.

  2. High-Ticket Conversion Architect

    Designs landing pages that close $10k+ offers. Intent-friction ratio, proof of work, selective enrollment.

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 support without an agreed scope or owner.

    We assess legacy systems and agree maintenance, extensions or modernization from what we find. Access, responsibilities and ongoing support terms need to be explicit.

    Better fit Software Takeover
  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.

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.

No hours tracked in either model.

TWO WAYS TO WORKONE STANDARD

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, no questions asked. Retainers cover the latest paid week. Fixed-price work covers the milestone agreed in your signed offer or statement of work. This is not an automatic refund of an entire project. Prepaid developer hours are a separate offer with their own published terms.

Latest paid week or agreed fixed-price milestone. No explanation of dissatisfaction required.

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.

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.

Choose the scope you need

For a public site and editorial workflow, use website development. For systems that need to exchange records, use API integration. For external self-service, use customer portals. If the build decision is still open, start with Discovery and Requirements. Existing-system changes begin with Software Takeover rather than a blanket rejection based on age.

Ampass headquarters, Vienna location

Our headquarters remains in Ampass, Tirol. We also have a Vienna location at Klimmschgasse 2/3, 1030 Vienna. Work is remote-first; agree any in-person session and its scope in advance through contact.

Less chasing. Clearer decisions.

Send the documents, rough notes or a screen recording you already have. We draft the brief and acceptance checks, keep product context in your repository, and send a short decision digest: recommendation, alternatives, cost, evidence, owner and latest useful decision date. You approve material choices. Complex coordination is scoped separately.

See the illustrative decision, release and handover evidence.

We prepare. You decide.

On eligible done-for-you work, we target at most 45 minutes of routine sponsor review per week, counting reading, meetings, messages and ordinary feedback across your nominated reviewers. Setup, operator trials and decisions requiring business authority have separate time allowances agreed in advance. We also record total client time. If our preparation causes the routine target to be missed for 2 consecutive eligible weeks, we change the format and take over the extra preparation without an added fee. Fractional Co-Founder remains an active collaboration.

Agree first use, future changes and the operating budget

Define one complete business journey and its technical acceptance before implementation. Where useful, reserve a stated part of the quote for a small cohort, realistic data, role setup, short instructions, an observation window and one correction cycle. We distinguish assisted first use from repeat unassisted use. List the three likely next changes and demonstrate one agreed operator change. Agree hosting, tooling, support and adoption costs so the first release leaves funds for operation and revision. Larger rollout and recruitment are separate; demand is not guaranteed.

One-off package: the acceptance and fee-protection milestones below apply. Weekly-retainer and Fast Lane terms belong to their own engagements.

First-use observation

See whether a small real cohort can repeat the intended task.

10 business days of observation after the agreed first-use event.

€2,000 net, one-off
  • One existing journey and up to 5 users recruited by the client.
  • Realistic data, role setup, short instructions, usage evidence and one correction cycle.
Check readiness and a delivery slot →

Before booking: Working product, participant access, consent, a named business owner and a bounded observation/correction scope.

Payment milestones: €1,600 for accepted setup/observation evidence; €400 for completed agreed review and correction obligations. No fee is earned merely by deploying an unused feature.

Scope, acceptance and fee protection

What earns the fee: Deliver the agreed observation, task evidence and correction; distinguish assisted completion from later unassisted repetition and report low participation honestly.

Scope limits: Recruitment, larger rollout, material new features and continuing customer success are separate. Demand and repeat use are measured, not guaranteed.

Your agreed milestone is corrected once within 5 business days. If it still fails, its unearned fee is waived or prepaid unearned amounts refunded within 10 business days. If Wavect’s failure makes the whole package unusable, we refund the whole package within the same 10 business days after that correction opportunity. Scope, acceptance and any client/vendor waiting are recorded before booking; we show the reason and revised date when a dependency pauses the affected clock. These package terms are written into your scope and preserve your existing rights. For these packages, business days are Monday to Friday excluding Austrian public holidays; dates use Europe/Vienna. Separately, our satisfaction guarantee covers the agreed fixed-price milestone: its fee is refunded if you are not satisfied, without requiring an explanation.

Make ownership something another person can demonstrate

Make ownership practical: another competent person follows your instructions and performs the agreed operating tasks. Classify the three most likely changes as self-service, supported work or a new quote. A proportionate handover remains part of an eligible build; the package below adds a fuller rehearsal for a known system.

One-off package: the acceptance and fee-protection milestones below apply. Weekly-retainer and Fast Lane terms belong to their own engagements.

Operational independence exercise

Another competent operator proves they can run the agreed tasks.

Within 5 business days of the booked ready start and operator slot.

€1,250 net, one-off
  • One skilled receiving operator; one service, environment and existing data source.
  • Clean setup, staging deployment, existing restore/export and one routine configuration/content change.
  • Up to 1 GB disposable sample; session up to 90 minutes; one correction/retest.
Check readiness and a delivery slot →

Before booking: A known system with working setup, deploy and recovery procedures, authorized access and an operator with the agreed baseline skills.

Payment milestones: €1,000 for accepted preparation and corrected instructions; €250 earned on the successful agreed rehearsal.

Related delivery: IKB. Handed the platform over to the in-house team and remained available as external support.

Scope, acceptance and fee protection

What earns the fee: The agreed tasks pass using corrected, client-owned instructions without hidden author knowledge. We record hints, permissions, remaining gaps and whether the receiver is a Wavect substitute or external operator.

Scope limits: New backup infrastructure, broken deployment repair, novice training and complex recovery investigation are separate. Baseline handover already owed under a build is not charged again.

Your agreed milestone is corrected once within 5 business days. If it still fails, its unearned fee is waived or prepaid unearned amounts refunded within 10 business days. If Wavect’s failure makes the whole package unusable, we refund the whole package within the same 10 business days after that correction opportunity. Scope, acceptance and any client/vendor waiting are recorded before booking; we show the reason and revised date when a dependency pauses the affected clock.

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.
