Mosaic Ventures

Mosaic Ventures is a London-based early-stage venture firm with a long-running thesis around European Series A investing in software, marketplaces, and selective frontier categories, with partners who bring institutional pedigree from US and European venture. The firm has historically backed category-defining software companies and has selective exposure to digital health, fintech-adjacent health, and AI-enabled vertical software. Healthcare exposure is incidental rather than central; expect interest in healthcare software companies that are fundamentally software-style businesses with strong unit economics rather than care delivery or regulated products. AI focus is real and applied, with interest in AI-native vertical software and infrastructure plays. Stage is typically Series A with selective Seed leads, and check sizes plausibly run from USD 3M to USD 10M for initial positions with capacity for follow-on. This is the wrong door for therapeutics, devices, or pure care-delivery businesses where the moat is clinical operations rather than software. It is a fit for European Series A-stage healthcare software founders with strong product, retention, and early enterprise pipeline who want a thesis-aligned European lead with US-quality diligence. Entry path is a warm introduction from a portfolio CEO, a co-investing seed fund, or a transatlantic operator; the partner team is small and selective, so cold outreach should be unusually well-targeted to land. Bring clean metrics and a clear category-leadership narrative.
