Business continuity since 1972

Maurice Tchenio
A founding figure of European private equity
At a time when private equity was still in its infancy in Europe, it helped to adapt and deploy this asset class from the United States.
For more than forty years, he has been actively involved in building the industry, working alongside some of Europe's leading entrepreneurs. He helped lay the foundations for European private equity, participating in the structuring of the first vehicles, the establishment of investment discipline and governance standards, and the organization of dialogue with major institutional investors.
A founding member of AFIC (now France Invest), he supports the professionalization of the French and European private equity market andhelps establish its standards.
In 1995, he also founded Altamir, the first 100% private equity evergreen vehicle listed in Europe—a structural innovation aimed at placing the asset class within a regulated and sustainable framework.
At the same time, he developed a pioneering approach to venture philanthropy, applying private equity principles to the creation of educational organizations with a strong social impact through the AlphaOmega Foundation.
Amboise Partners has thus become a recognized platform within the European institutional ecosystem.
Frédéric Stolar
An international career path
In 2021, Frédéric Stolar joined Maurice Tchenio at Amboise Partners to start a new chapter for the asset management company.
Frédéric Stolar has over thirty years of international experience in private equity.
He began his career at Apax alongside Maurice Tchenio, before joining Warburg Pincus in London, one of the global leaders in the sector.
He then founded and ran Sagard for nearly 20 years, a European private equity platform backed by leading industrial families, including the Desmarais family (Power Corporation of Canada) and Albert Frère (GBL). Under his leadership, Sagard established itself as a recognized player in the European mid-market.


A shared conviction
Structuring institutional access for private savings
Maurice and Frédéric have had a professional and personal relationship for over thirty years.
Throughout their careers, they have worked with some of the world's largest institutional investors and wealthiest international families.
They observed, over several cycles, the quality of performance generated within a rigorous institutional framework based on discipline, selectivity, and alignment of interests.
At the same time, they noted that the offering for private investors remained fragmented and often fell short of institutional standards.
This observation gave rise to a shared conviction:
- the asset class is a key driver of long-term value creation;
- Private savings deserve the same level of requirements and structuring as institutional capital.
- It is possible to build an independent European private equity player, designed from the outset to meet the specific needs of sophisticated private investors and their advisors.
In 2021, Maurice Tchenio and Frédéric Stolar decided to embark together on a new cycle of development based on this shared vision.
Amboise Partners then embarked on a strategic transformation aimed at establishing an independent private equity player dedicated to private clients.
From the outset, the project has been designed as a sustainable European platform with a long-term perspective.
Key milestones in the development ofAltaroc
The year 2021 marks the operational implementation of this new ambition.
Frédéric Stolar joins Maurice Tchenio as a shareholder, marking the start of Amboise Partners' transformation.
Work begins on structuring the proprietary technology platform, laying the foundations for an integrated and scalable digital model dedicated to private equity.
In 2022, the company launched its first 100% private equity vintage portfolio for private investors.
The Odyssey range is structured on an annual basis, with an FPCI version in France (Altaroc Odyssey ).
The momentum of the first vintage confirms that there's a lot of interest from private investors in getting into private equity based on institutional standards.
It supports the structuring of a network of wealth management partners and marks the effective start of the platform's operational rollout.
In 2023, Amboise Partners officially became Altaroc , marking the start of a new chapter and affirming its European ambitions.
The company is rolling out the Re-Up program, whichadapts the recurring allocation mechanisms historically used by institutional investors in private equityto private investors .
At the same time, the technology platform is being consolidated to ensure transparency of flows, detailed portfolio monitoring, and disciplined allocation management.
The year 2024 marks a stage of acceleration and internationalization.
The Infinity range has been launched to offer mandates dedicated to significant wealth.
At the same time, international vehicles are being structured with the launchHorizon and then RAIF, enabling the company to support development outside France and accompany the management company's rise to prominence in Europe.
This phase marks a geographical expansion and a controlled diversification of the offering.
In 2025, Altaroc continues its development with the launch of the Discovery range, comprising Discovery in France and Altaroc Evergreen internationally.
This evergreen secondary private equity offering, aimed at private investors, complements the platform's solution architecture and strengthens its European positioning.
In the same year, key employees were given a stake in the company. This change in governance strengthened the alignment of interests and consolidated the group's structure with a long-term perspective.


A trajectory built to last
In just a few years, Altaroc has embarked on a structured development based on the institutional experience of its founders and an organization designed to support long-term savings.
In line with Amboise Partners, the company has a clear ambition: to build a leading independent European player, applying the standards of rigor and governance of institutional private equity to private clients.
