Investment thesis
Seido Capital backs founders in life sciences, biotech, and healthcare-focused deep tech, from pre-seed through Series B (and up to IPO). It focuses on three core sub-sectors: biotech (research, therapeutics, technologies), life sciences (medical devices, diagnostics, digital health tools), and AI for healthcare delivery and research. The firm emphasizes high growth potential, rapid international expansion, and a clear path to mid-term exits. Its process spans project reinforcement (partnering with incubators and universities), rigorous qualification, investment committee review, deal structuring using both dilutive and non-dilutive capital, and long-term post-investment support. It replicates the European Theodorus model in North America.
