About Sermo
Sermo is a medical community and social network for healthcare professionals headquartered in New York, United States. It offers on-demand access to physicians and healthcare professionals.
On the one hand, it offers tools for healthcare professionals to connect and discuss, and to monetize their knowledge through surveys. To market research firms, Sermo gives access to its network, helping them run surveys with the members.
The platform has grown substantially in recent years; as of 2024, Sermo says it supports over 1.5 million members across more than 150 countries, including more than 1 million triple-verified healthcare providers as of an October 2025 product announcement. Beyond standard survey access, Sermo produces its own research output, including the recurring "Sermo Barometer" physician-sentiment survey series (covering topics such as burnout, psychedelic treatment attitudes, and COVID-19 treatment requests), which has been cited in academic and industry research. In 2025, the firm publicly launched a Drug Ratings tool and relaunched its Sermo Mobile platform, alongside an Engagement Manager product enabling on-demand advertising access to its physician community.
