"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."

About ConsultWave

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.

Senior from day one

The person who scopes your engagement is the person who delivers it. No handoffs to junior teams mid-project.

Evidence over opinion

Recommendations are built on your numbers and your market, not on a template we reuse across clients.

Built to outlast us

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.

Our approach

A five-stage way of working, held to on every engagement.

01

Discover

We spend the first stretch listening — to your team, your numbers and the constraints nobody wrote down. No recommendations yet.

02

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.

03

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.

04

Deliver

We stay through the first phase of execution — entity filings, board presentations, hiring plans — whatever the plan actually requires.

05

Sustain

We hand over frameworks your team can run independently, and check back in at an interval that matches the size of the change.
