With over 50 years of experience, the firm leverages relationships with leading global managers to design turnkey private equity programmes aligned with the standards of the largest institutional investors.
Altaroc enables private clients to invest alongside pension funds, sovereign wealth funds, and leading family offices in top-tier private equity funds, while contributing to the financing of the real economy.
Founded in 1972 by Maurice Tchenio, Altaroc traces its roots to one of the pioneers of private equity in Europe.
Over several decades, the firm played a key role in the development of the Apax funds, contributing to shaping the private equity industry for the long term.
As early as 1995, the firm also distinguished itself by supporting the launch of Altamir, France’s first publicly listed evergreen private equity vehicle, thereby opening access to this asset class for private investors.
Known successively as Apax SA and then Amboise Partners, the firm became Altaroc in 2024, marking a new phase in its development.
In 2021, Frédéric Stolar joined Maurice Tchenio to support Altaroc’s strategic development and expansion toward private clients. With over 35 years of experience in private equity, he began his career alongside Maurice Tchenio at Apax.
He subsequently worked for several leading U.S. investment firms before leading Sagard for nearly 20 years, alongside the Albert Frère and Paul Desmarais families.


Altaroc’s vision is based on a unique model built around four key pillars:
- Open architecture and a rigorous selection process: To build effective portfolios, Altaroc selects each year a range of the world’s leading funds, across both primary and secondary markets.
- Institutional governance : Fund selection and manager due diligence are conducted within a structured and proven framework, ensuring investment discipline, alignment of interests, and quality of execution.
- Transparency & Trust: In an industry traditionally defined by confidentiality and discretion, Altaroc is committed to explaining its investment decisions and enabling clients to monitor them through detailed reporting and high-quality content.
- Continuous innovation: Altaroc has disrupted the institutional market by developing innovative solutions across product design, technology, and services. Through its digital platform, the firm provides a seamless experience and simplified investment management.
Investment, finance, legal, regulatory, reporting, middle and back office, operations, and technology teams: all these areas of expertise come together to deliver the highest standards.
To align the firm’s ambition with the potential and quality of its teams, the two founders have already offered 10% of the equity to key managers. This strong commitment from the executive shareholders is at the heart of Altaroc success and enables the firm to further solidify its position as an innovative leader in private equity every day.
