We are a Portuguese company with international ambition, fascinated by the world surrounding us. Organising congresses and conferences is our passion. We were born in Portugal, but we grew up thinking about the world and how it connects through communication and knowledge sharing. For us, organising conferences is about connecting people around a greater goal or a common dream: accelerating a cure for a disease, bringing more visibility to a campaign, or even creating a movement for real and lasting change. These special moments of knowledge sharing, innovation and best practices live on well beyond the day of the event. And that legacy is what drives us: building bridges between people and creating unexpected opportunities for collaboration. WE LISTEN AND DELIVER At Leading, we are eager to understand and turn our clients' visions real. From event to event, we have consolidated our experience in areas as different as Chemistry, Health or the Social Sciences. This means that today we are trusted by national and international associations and societies to organize their events, something that fills us with that happy feeling of a job well done. What We Do: Virtual Events, Webinars and Virtual Conferences, Virtual Exhibition Concepts and 3D Stands, Event Technology, In-person Conferences and Scientific Congresses, Association Management, Sponsorship Sales, International Bid Proposal, Tradeshows, Destination Management, Corporate Events.
