Background
Guillaume Cornet is a Belgian national who currently serves as a Director at Keensight Capital, a European growth-buyout private-equity firm specializing in the Technology and Healthcare sectors (~€7bn AUM). He works on the firm's growth-equity investments in profitable, expanding companies across Europe.
Before joining Keensight, Cornet was an Investment Manager at BlackFin Capital Partners — the leading pan-European financial-services private-equity platform — where he worked out of both the Paris and Brussels offices. According to his official bio, he was "involved in several transactions in Europe and participated in developing portfolio companies' organic and inorganic growth," reflecting a hands-on role in deal execution and post-investment value creation. His BlackFin email and Paris phone line are what appear in the original stub record.
Earlier in his career, Cornet worked in the Investment Banking Division of Goldman Sachs in London, and began his career at BNP Paribas CIB in Paris, advising clients across multiple sectors. This path — bulge-bracket investment banking into financial-services PE and then technology/healthcare growth equity — is a common route for European buyout professionals.
He holds both a B.A. and an M.Sc. in Business Engineering (Ingénieur de Gestion), with a finance concentration, from the Solvay Brussels School of Economics and Management (studies circa 2012–2014).
Investment Thesis & Focus
- At Keensight Capital (current): targets "fast growing and profitable" companies in attractive niches of Technology and Healthcare, providing capital, strategic guidance and operational support as a European growth-buyout investor.
- Company profile: profitable businesses with revenues of roughly €10m–€400m; equity tickets of €10m–€400m per deal.
- What makes them say yes: demonstrated profitable growth, exposure to structural growth drivers (digital transformation, healthcare innovation), and management teams open to a partnership-style, value-creation approach.
- At BlackFin (former): focus on financial-services businesses (insurance, asset management, fintech, banking services) across Europe, with emphasis on both organic and buy-and-build ("inorganic") growth of portfolio companies.
- Stage: growth buyout / expansion capital in established companies — not angel or seed investing, despite the label in the original stub data.
Notable Investments
- BlackFin Capital Partners — pan-European financial-services buyouts and build-ups; Cornet is credited with working on "several transactions in Europe" and supporting portfolio companies' organic and M&A-driven growth.
- Keensight Capital portfolio — European technology and healthcare growth-buyout deals; the firm reports 69 companies invested and 48 exits over 20+ years, at a ~39% gross IRR and ~3.4x gross multiple.
- Dimo Maint — Keensight signed an exclusivity agreement to acquire this European leader in CMMS (maintenance-management software), illustrative of the tech-software deals in his current firm's pipeline.
