Investment thesis
Seido Capital backs founders in life sciences, biotech, medical devices/diagnostics, digital health, and AI-driven healthcare, from pre-seed through Series B and up to IPO. Building on two decades of the Theodorus ULB spin-off model, the firm scouts breakthrough technologies at universities and research centers, offering advisory support before companies exist. It applies a rigorous five-phase process (project reinforcement, qualification, investment committee, deal structuring, closing) and combines dilutive and non-dilutive capital. Positioned near major US pharma and life sciences hubs, Seido targets high-growth ventures with rapid international expansion and clear mid-term exit paths, providing hands-on strategic, network, and operational support to build global healthcare leaders.
