Paul Gatti

Paul Gatti is co-founder and CEO of CompareNetworks, a South San Francisco-based B2B media and technology company he built from a postdoc's side project into a 12-brand portfolio serving 8 million science and engineering professionals. Trained as a microbiologist at Tulane and UCSF, Gatti pivoted from the bench to the boardroom around 2000, assembling a media empire that connects buyers and sellers across life sciences, pharma, engineering, and industrial sectors. Under his leadership, CompareNetworks has grown via strategic acquisitions — GlobalSpec in 2020, Gulf Energy Information in 2025 — backed by Main Street Capital since 2019.
