Is OW worth exhibiting?
Why Exhibit
ObesityWeek is the epicenter of the obesity medicine revolution, driven by the GLP-1/GIP agonist boom (semaglutide, tirzepatide). Attendance is growing rapidly as obesity moves from niche to mainstream medicine. At $3,700 per 10x10 (standard rate) with corporate symposia and product theater options, the show offers strong value. The joint TOS/ASMBS format brings both medical and surgical obesity leaders.
Why Skip
Still a mid-size conference (~3,500 attendees). If you are not in obesity medicine, bariatric surgery, or metabolic disease, there is no audience here. Pharma companies (Novo Nordisk, Lilly) dominate the show floor. Smaller device companies may feel overshadowed.
What should exhibitors know before OW?
ObesityWeek is the hottest-growing medical conference in the US right now, riding the GLP-1 wave. Novo Nordisk and Lilly are anchor exhibitors. The Gaylord National Resort keeps attendees on-site. Non-profit rates ($900) make this accessible for academic medical device startups. Book early. The early rate deadline is May 4.
