About This Fund
ISAI Venture IV is the fourth early-stage venture capital fund from ISAI, France's pioneering tech entrepreneurs' fund co-managed by successful founders of the French Tech ecosystem. Founded by serial entrepreneurs who built some of France's most prominent digital companies, ISAI manages approximately EUR 550 million in assets across four investment strategies: early-stage venture capital, late-stage venture capital, private debt, and growth/buyout. ISAI Venture IV targets a total size of EUR 100 million and held its first closing at EUR 75 million — representing three-quarters of the target — in December 2025, with anchor support from Bpifrance and a community of entrepreneur-limited partners drawn from ISAI's extensive alumni network.
The fund invests at the pre-seed and seed stages in capital-efficient French and Europe-based technology companies demonstrating early commercial traction or strong product-market fit. Primary tickets range from EUR 1 million to EUR 3 million, with a dedicated pre-seed allocation of 10% of the fund for investments of EUR 100,000 to EUR 500,000 in the earliest-stage opportunities. ISAI's thematic focus for this vintage spans artificial intelligence applications, decarbonisation technologies, marketplace platforms, and SaaS business models with strong unit economics. The fund targets companies positioned to become market leaders in their respective categories, with a geographic mandate of 80% in France and the remainder in US-based ventures founded by French entrepreneurs.
ISAI's earlier venture funds produced some of France's most celebrated digital success stories, including early investments in BlaBlaCar, Malt, 360Learning, Prose, Alma, and Flowdesk. This track record has established ISAI as a top-tier French early-stage investor and attracted a high-quality LP base including leading family offices and founder-entrepreneurs from prior portfolio companies. Classified as an Article 8 fund under the EU Sustainable Finance Disclosure Regulation, ISAI Venture IV incorporates environmental and social characteristics into its investment screening process. The fund is currently in active fundraising ahead of its target final close.
