We continue to have great discussions and footfall around our stand with no need to try and encourage people to come and see us. Really positive event for us and we look forward to working with Convenzis in the future.

My colleague and I presented at the NHS workforce conference 2023, 19 September. The support and guidance we received from the Convenzis team in the run up to our presentation slot was great, well timed and perfectly pitched. The event itself, again was expertly organised. The conference was well Chaired by Sean, who was very engaging. As an audience member as well as a panel member, I would definitely work with the Convenzis team again.

Working with Convenzis is a stress-free and a rewarding experience, with fantastic engagement from a highly targeted and relevant audience


I worked with Convenzis, primarily Dan, for the first time this year, putting together a bespoke online event for IBM. He has always been so responsive and accommodating. The team always remained professional and helpful – despite the many demands from our side! They were very keen for us to maximise on the investment and revisit those attendees who had not committed to follow ups.
It was an absolute pleasure doing business with Convenzis and I know there will be more opportunities next year. Looking forward to it!
