François Collet is a General Partner at ISAI who brings an unusually broad capital-structure perspective to early-stage investing, having started in LBO financing at Crédit Agricole CIB before moving into venture capital. He is known for his vertical AI thesis, emphasizing that the most compelling AI startups are built by founders with deep domain expertise applying AI to specific industries rather than general-purpose AI solutions.
