The No-Bullshit Guarantee. Cancel any week, refund the last.

Fractional Co-Founders

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.

BEFORE YOU APPLY

Who Fractional Co-Founding is not for.

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.

  1. You already have a CTO who owns product and engineering.

    You don't need a fractional partner, you need delivery capacity. Our development retainer is built for that.

    Better fit Software Development

  2. You can't put four hours a week into the build.

    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.

    Better fit Software Development

  3. Your business is already profitable and you just need engineering capacity.

    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.

    Better fit Software Development

  4. You want a co-founder who'll trade 20% equity for cheap hours.

    We charge €400 a week. That is the deal. We are not an equity hack and we won't pretend otherwise.

  5. Your bet depends on a market that doesn't exist yet.

    "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.

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.

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.

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

Applies to weekly retainers (Fractional Co-Founder, Software QA, and Software Development Retainer). Fixed-price projects deliver against a signed contract; that's a different (and equally honest) mechanism.

Cancel any week.
Refund the last week.
No hours tracked.

First week not worth it? Refunded, no questions.

Product Decisions, De-Risked

Most founders guess and burn six months. We decide with data, before the first line of code.

FAQs

Common questions about our Fractional Co-Founder program

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.
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.
Consultants give recommendations and leave. Business analysts document requirements. We become deeply invested in your product’s success and work hands-on to validate, iterate, and define your roadmap. We don’t just analyze, we experiment, test assumptions, and prepare everything needed for successful development. Think of us as your product co-founder during the critical strategy phase.
Absolutely! Having an idea is just the starting point. We help you validate if people actually want what you’re planning to build, identify the core features that drive adoption, prioritize your roadmap for maximum impact, and create detailed specifications developers can work from. Most ‘great ideas’ change significantly once they meet real users.
We use lean validation methods including user interviews, landing page tests, prototype validation, vibe-coded prototypes, competitive analysis, and market research. We test assumptions before committing to development. By the time we’re done, you’ll have real user feedback, validated demand signals, and a roadmap based on actual market needs, not just assumptions.
You get a complete product development package: validated product roadmap with prioritized features, detailed user stories and technical requirements, proven Product-Market Fit signals, competitive positioning strategy, and everything your development team needs to start building immediately. Essentially, a blueprint for building the right product.
That’s exactly what this phase is for! Direction changes are normal and healthy, it means we’re learning and adapting based on real market feedback. We help you navigate pivots strategically, ensuring changes are data-driven rather than guesswork. Many successful products look different from their initial concept.
This is the essential first step in our 3-stage journey. Once your product strategy is solid, you can seamlessly transition to our Software Development phase with a clear roadmap and validated requirements. This saves you the typical 2.5k€ discovery phase since we’ve already done the strategic groundwork. Alternatively, we can also just start with the Discovery phase and develop right away.
Most clients see initial clarity within 2-3 weeks, with a solid, validated roadmap typically ready in 4-6 weeks. However, we work until the direction is genuinely clear and validated, we don’t operate on fixed timelines but on achieving the right outcomes. You can cancel anytime and get last week refunded if you’re not seeing progress.
Sure, we can continue providing strategic product guidance while also ensuring your development stays on track. Many clients benefit from ongoing product strategy support as they learn from real users and need to evolve their roadmap.
