M24 Private Office is a Luxembourg-based single-family office, founded in 2024, at the head of the M24 group, whose companies invest in different countries. It allocates capital to public markets, European real estate and selective venture investments. The group came to us on the recommendation of a partner we work with in London.
A group with a scatter of sites
M24 is a family investment group with companies in several countries, and each company had its own site, made at different times by different hands. The owner and his top management asked for one thing: a single umbrella brand that presents the group as what it is, a family business, with restraint and taste. The family had to be visible; nothing could look like a fund selling a product.
Why calm, not loud
Calm tones, minimalism and precision were our recommendation, not a style choice. Loud sites do not work where people invest money: an investor wants calm and certainty, so every line, colour and spacing has to be exact. We built the brand as one system for the group, and gave each company its own voice inside it.
The family office: the family in the imagery
The office is where the family shows most. Its site carries the family theme in imagery made in the manner of bas-reliefs and frescoes: a sense of heritage and continuity across generations, without a single family photograph. The companies that invest, M24 Invest and M24 Arvian, got the stricter version of the same brand: angular forms and buildings.
Built for the room where it is shown
The group goes to family-business and investment conferences, where what it has to show first is that it is a family business. The site is one page in the order those conversations go: the mission; the principles of discretion, alignment and discipline; where the office invests; the three investment lines, public markets, real estate and venture; and the people behind them.
After launch, we stay
Every month we support the site: edits, optimisation, on-site SEO, backups, and a fast answer when the team or their lawyers need a change, because legal wording on an investment site must be exact. In October 2026 we moved it onto our own design system: 98 on Google PageSpeed for phones.
