Frequently asked questions

Who runs investment decisions at Altur Investissement?

François Lombard and Gilles Marceau jointly lead the investment committee. Lombard, the firm's President, and Marceau, the Managing Director, have operated as a partnership since the firm's founding in 2007. Their prior experience at BNP Paribas and CDC Enterprises shaped the firm's focus on proprietary, non-auction deal sourcing in the French lower mid-market.

How does Altur Investissement source proprietary deal flow?

Altur emphasizes bilateral, privately negotiated transactions rather than competitive auction processes. The firm targets founder-owned SMEs in France, Italy, and Spain where succession and ownership fragmentation generate deal flow that does not appear on broadly marketed processes. The lean team structure reinforces this model, concentrating origination in the hands of the two senior partners.

Does Altur Investissement operate a traditional closed-end fund structure?

No. Altur Investissement uses an evergreen investment vehicle, which differs from the standard 10-year closed-end fund. This structure removes fixed deployment and exit deadlines, allowing the firm to hold platform companies for extended periods. A 2022 capital reorganization formalized the firm's independence from prior institutional sponsorship.

What size of company does Altur Investissement typically target?

The firm targets lower-mid-market companies, typically with enterprise values between €10 million and €50 million and revenues ranging from €10 million to €75 million. Transaction types include majority buyouts, management buyouts, and growth equity. The firm does not participate in seed-stage or venture-stage technology investing.

Where does Altur Investissement invest geographically?

The firm's primary markets are France, Italy, and Spain. The team operates exclusively from Paris and concentrates on regions where the partners have long-standing networks and where fragmented, founder-led SME ownership structures are prevalent. Altur does not invest in North America, Asia, or the UK.

Which sectors does Altur Investissement explicitly avoid?

Publicly available information indicates the firm does not invest in real estate, infrastructure, natural resources, hospitality, or financial services. The portfolio is concentrated in enterprise software, digital health, industrial technology, and business services — sectors where the partners have operational and transactional experience.

Does Altur Investissement co-invest alongside external GPs or limited partners?

The firm does not publicly disclose its posture on co-investments. Given the evergreen structure and lean team, Altur typically executes platform investments independently. There is no evidence the firm operates a co-investor club or syndicates deals systematically with external limited partners.
