Embedded product and engineering thinking for the pre-PMF gap. €400/week, cancel anytime, no equity, no fluff.
First week not worth it? Refunded, no questions.
Switch off what your founding team already covers. What stays lit is the seat we fill.
Before writing a single line of code, let's make sure you're building the right thing. Most startups don't.
Define Your Product Roadmap
Every feature earns its place by driving adoption or revenue. Or it doesn't ship.
Avoid Building The Wrong Thing
We validate demand and market fit before you spend months building something nobody wants.
Fast Product-Market Fit Validation
We run fast experiments so you know what the market wants before burning budget.
Ready-to-Build Specifications
You leave with a dev-ready blueprint your engineering team can execute on day one.
Technical & Business Expertise
We balance market needs with technical reality, so your roadmap is feasible, not just ambitious.
Lean Validation Methods
Prove demand with landing pages, prototypes, or user interviews. Whatever's fastest.

How many founders ship before talking to users?
Too many.We make sure you're not one of them.
See how we turn chaos into clarity, in repeating 4-week cycles.
After Phase 04, the cycle loops back to Phase 02
After this week, we begin a new cycle with weekly tasks (similar to weeks 6-8), building on our learnings and progress.
Free skills · No API key · No signup
Same PMF, ICP, and pricing prompts we run inside engagements. Plug them into your own AI workflow. No API key, no signup.
Pressure-tests your idea against JTBD, Sean Ellis, RICE. Won't let you confuse user love for a business.
Forces specificity: name the customer, the trigger, the spend, where to find 50 of them.
Kills cost-plus thinking. Surfaces the value metric and the price the market actually pays.
BEFORE YOU APPLY
Saves us both a call. If two or more of these describe you, the diagnostic will end in a polite no, and we'll point you toward the right room.
You don't need a fractional partner, you need delivery capacity. Our development retainer is built for that.
Fractional is co-, not solo. If you can't be in the room with us, the outcome won't be yours. A done-for-you build is a saner deal.
Fractional is for the pre-product-market-fit gap. If you've already found PMF and need execution muscle, our development retainer is the right shape.
We charge €400 a week. That is the deal. We are not an equity hack and we won't pretend otherwise.
"Mass crypto adoption," "people will pay for AI companions." We work with operators, not lottery winners. If the plan is hope, we're not the right partners.
We'd rather refund €0 today than refund €40k in six months. Saying no early is the most honest thing we do.

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.

Maintain & Speed Up
Note: We also test products built by other teams, including vibe-coded software. New features and adjacent products are scoped separately as software development.
We win when you win. That's the alignment.
No notice period, no exit fee, no questions.
Latest paid week or agreed fixed-price milestone. No explanation of dissatisfaction required.
We work to exceed expectations, not to fill timesheets.
Fixed-price guarantee
Money back for the agreed milestone. No questions asked. The signed scope and deadline still apply.
WHY THIS WORKS
Not our model: Pay by time
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.
Not an add-on. Part of the deal.
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.

Most founders guess and burn six months. We decide with data, before the first line of code.
Took a vibe-coded prototype to enterprise pilot-ready, no shortcuts.
Split a GPU-heavy monolith into orchestrated services and swapped self-hosted ML libs for scalable alternatives. Latency and cost …
Proprietary real-time proximity matching on iOS/Android against aggressive OS throttling, full stack.
These are selected projects, not our full portfolio. We have shipped 75+ products since 2018.
Built multiple venture-backed startups with Wavect over 4 years. World class team. They're great thought partners while in discovery, reliable and predictable engineers while in dev, and just generally great guys to work with. Highly highly recommend you work with this team for your next project.
Kevin is extremely knowledgeable and professional, and I'm grateful I had the chance to meet with him about a business idea. His insights were some of the most impactful ones I've received and made a real difference in shaping my direction.
He's bright, adventurous, and never shies away from a challenge. I truly admire his innovation, resourcefulness, and ability to make things happen. Kevin is one of a kind, and anyone who works with him will quickly see the unique value he brings.
Earned my trust for future cooperations. An extremely dedicated and passionate but also well-trained and reliable team. Based in Tirol, working internationally.

Bring the product or technology question. We prepare a short recommendation with alternatives, evidence, consequences, next priorities and an owner. The €400/week Fractional Co-Founder partnership still requires your active participation, including the published four client hours weekly. It is not a low-attention delivery plan. Larger investigations and implementation need separate scope.

One-off package: the acceptance and fee-protection milestones below apply. Weekly-retainer and Fast Lane terms belong to their own engagements.
First technical hire support
Comparable technical evidence for your hiring decision.
Interview slots and the report date are agreed before booking.
Before booking: Live product, funded role, candidate permission and a client hiring decision-maker. We confirm fit and available interview slots.
Payment milestones: €500 for accepted role and assessment preparation; €2,000 for completed agreed interviews and evidence reports. Agree the candidate count before booking. The assessment fee is earned proportionately for completed, accepted agreed interviews/reports; any undelivered share remains unearned.
What earns the fee: Deliver the agreed scorecard, consistent assessments and a documented recommendation. Your team makes the hiring decision.
Scope limits: No sourcing, placement or hiring guarantee, employment advice or substantial product onboarding. Further onboarding is separately scoped.
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.
