Summary
Giovanni Tummarello is a serial founder, product-led CEO and computer scientist with 11 years of commercial experience building AI-enabled analytics and intelligence platforms from research prototypes to paying customers. He founded and led Siren from bootstrap to award-winning product and customers across pharma, finance and national intelligence, blending semantic knowledge representation with high-performance big data joins. Now leading Octostar, he focuses on investigator-facing intelligence tools that speed discovery and simplify operations, while retaining deep hands-on experience as a researcher, engineer and product designer.
