What Havas SO does

Havas SO is a privately held healthcare communications agency headquartered in London, United Kingdom. The firm operates as a specialist unit offering public relations, medical communications, and advertising services to clients in the healthcare sector. Its service portfolio spans the three core disciplines of healthcare marketing communications — earned media and stakeholder relations, scientific and medical communications (typically involving publications, medical affairs support, and HCP-facing content), and paid/creative advertising — indicating a full-service positioning within its narrow vertical.

The company operates with a small headcount of 11-50 employees, consistent with a boutique specialist agency model rather than a scaled full-service network. The "Havas" prefix indicates affiliation with the global Havas communications group, though the specific structural relationship (wholly owned subsidiary, operating division, or licensed network member) is not disclosed in the available source material, which was limited to a loading/verification screen on the corporate website.

The firm's revenue model is not disclosed in the available data. No pricing models, publicly disclosed rates, customer logos, customer segments, management team, funding history, or technology stack details were present in the source material. As such, business model mechanics — including fee structures (retainer vs. project-based), media-buying economics, or margin profile — cannot be characterized from the supplied evidence. The addressable market is the UK and likely broader European pharmaceutical, biotech, and consumer health communications market, served through the Havas network's global reach.
