Helena Mancebo

Helena Mancebo is the founder and CEO of Multispan, Inc., a Hayward, California biotech she has run for more than 20 years. She built a company around G protein-coupled receptors (GPCRs) - still among the most prolific class of drug targets - and grew it into a maker of the industry's largest collection of highly characterized human GPCR cell lines and 1,600-plus assay tools. A Yale-trained immunologist and geneticist, she pairs hard cell biology with a service obsession: next-day assay turnaround, native receptor pharmacology, and a culture built on empathy, integrity, and productivity. In 2023 Multispan's cell engineering and assay services were folded into Avantor's catalog; in 2025 she partnered with AI-automation firm Synfini to push GPCR drug discovery forward.
