Nathalie Marquis

Nathalie Marquis is a Rouen-based investment professional at NCI (Normandie Capital Investissement), the independent regional private-equity and venture-capital firm managing roughly €300–400 million in assets across Normandy, Hauts-de-France, Brittany, Pays de la Loire and Île-de-France. She has been with NCI Gestion since 2007, where her work centers on the analysis and valuation of portfolio ("sociétés en participation") companies and on structuring the reporting and monitoring that the firm's funds rely on. She is associated with NCI's "pôle Performances" — a team of in-house consultants (reported as around seven) dedicated to value creation and hands-on support of NCI's investee companies rather than to sourcing new deals.

Her career before NCI was built in financial advisory and operations. From 2000 to roughly 2006 she was a consultant/financial analyst at GEFI, a firm advising SMEs on valuation, financial analysis and M&A. Earlier, she spent several years in an operational management role at GIPE, overseeing administrative, HR and social-insertion program functions (managing a facility of up to ~70 staff), and began her career in marketing and market-research consulting (Pro Consult / Proconsult) in the early 1990s.

Marquis is a graduate of the École Supérieure de Commerce de Rouen (ESC Rouen, campus Mont-Saint-Aignan — now part of NEOMA Business School), completing her studies around 1990. She has also taught financial analysis and company valuation as a visiting/adjunct instructor at institutions such as the IAE and CEPPIC.

Within NCI, her profile sits on the value-creation and portfolio-monitoring side of the firm rather than the front-line, deal-leading partner side: NCI's investment-committee leadership is headed by figures such as Anne-Cécile Guitton (Présidente), Stéphane Kerlo (Directeur Général), Hubert de Germay and Vincent Lhermenier (Transmission), and Yves Guiol (Innovation).

• Institutional, not angel: Marquis invests through NCI's managed funds (institutional investors, family offices and business owners), not as a personal angel writing individual seed checks.
• Full lifecycle coverage: NCI backs companies at creation/innovation, development and transmission (buyout) stages — majority and minority stakes in SMEs and mid-market companies.
• Regional "proximity" model: NCI positions itself as "more investors than financiers, more active partners than capital holders," pairing local teams with the resources of a national player.
• Seed/early-stage exposure via dedicated vehicles: capital-innovation activity since 2005, plus WaterStart Capital, an accelerator fund (launched March 2018) sitting between seed financing (love money, grants, business angels) and classic venture capital, targeting innovations with strong impact on the traditional economy.
• Value creation as the differentiator: her "pôle Performances" mandate is post-investment — diagnostics on market and business model, business-plan and dashboard support, and structured reporting to help portfolio companies grow.
