We help ambitious companies find their way through Europe's markets.
ConsultWave is an independent advisory firm based in Luxembourg, working with founders and executive teams on strategy, capital and cross-border growth.
Where we help
Six practice areas, one senior team. We stay close to the work rather than handing it off.
Strategy & Growth
Positioning, business model and expansion planning for teams ready to scale deliberately.
Financial Advisory
Capital structuring, fundraising support and financial planning grounded in real numbers.
EU Market Entry
Using Luxembourg as a base to structure and launch operations across the European Union.
Risk & Compliance
Governance frameworks and regulatory readiness built for cross-border operations.
Transformation
Operating model and digital transformation programmes that hold up after we leave.
M&A Advisory
Deal preparation, due diligence support and post-merger integration planning.
"ConsultWave didn't hand us a slide deck and disappear. They sat with our team through the Luxembourg entity setup and the first difficult board conversation that followed it."
— Managing Director, European logistics group
Built in Luxembourg, for companies moving into Europe.
ConsultWave was founded on a simple observation: Luxembourg sits at the centre of Europe's financial and regulatory map, yet most companies entering the market lack a partner who can navigate it with them, not just for them.
Today we work as a small, senior consultancy — no layers of junior staff between you and the people making recommendations. Every engagement is led by someone who has done the work before, in the sector you operate in.
What guides the work
Three commitments we hold ourselves to on every engagement.
The person who scopes your engagement is the person who delivers it. No handoffs to junior teams mid-project.
Recommendations are built on your numbers and your market, not on a template we reuse across clients.
We design frameworks your team can run without us, and we say so plainly when a project is finished.
Leadership
A small partner group covering strategy, finance and regulatory practice.

Partner, Regulatory & RiskAdvisory work organised around the decisions you actually face.
Strategy & Growth Advisory
We work through positioning, business model choices and expansion sequencing with founders and executive teams, then stay through the first quarter of execution.
Financial & Investment Advisory
Capital structuring, fundraising narratives and financial models that hold up under investor scrutiny, prepared with your finance team rather than around them.
EU Market Entry
Entity structuring, licensing pathways and go-to-market planning for companies using Luxembourg as their base for European operations.
Risk, Governance & Compliance
Governance frameworks, internal controls and regulatory readiness reviews built for the jurisdictions you actually operate in.
Digital & Operational Transformation
Operating model redesign and technology-enabled process change, scoped to what your team can realistically sustain after handover.
Mergers & Acquisitions Advisory
Deal preparation, commercial due diligence support and post-merger integration planning across the transaction lifecycle.
A five-stage way of working, held to on every engagement.
Discover
We spend the first stretch listening — to your team, your numbers and the constraints nobody wrote down. No recommendations yet.
Diagnose
We map the actual decision in front of you, separate from how it was originally framed, and pressure-test it against your market and regulatory position.
Design
We build the strategy, structure or model with your team in the room, so the reasoning behind it lives with you, not only in a report.
Deliver
We stay through the first phase of execution — entity filings, board presentations, hiring plans — whatever the plan actually requires.
Sustain
We hand over frameworks your team can run independently, and check back in at an interval that matches the size of the change.
Tell us where the decision stands.
