W2O’s mission of "pragmatic disruption of the status quo" has resulted in 13 consecutive years of growth for the independent network founded by Jim Weiss.
Under his leadership, the agency, which deems healthcare and tech as its specialties, has more than doubled its annual revenue in the past five years, growing from $25.8 million in 2009 to $69.7 million in 2013.
Weiss’ wealth of health experience has proved significant in W2O gaining a stronghold in the burgeoning digital health sector.
After opening a Boston office in March this year, he plans to strengthen W2O’s global footing, establishing strategic partnerships beyond its London hub in Europe, to include Asia and Latin America.
