Vendelux is offering event organizers a free way to expand their targeted marketing outreach data, provided they share their own data in exchange.
New York-based Vendelux has launched a free platform that lets event organizers trade attendee lists to expand their marketing reach.
The basic idea: An organizer uploads their confirmed attendee list and, in return, gets access to the same number of attendee profiles from similar events. For example, a fintech conference that shares 1,000 names would receive 1,000 profiles of people who attended other fintech events.
To protect privacy, organizers can’t see which exact events attendees went to — only that they’ve participated in similar industry gatherings.
Referred to as a data cooperative, the model allows organizers to control sharing. Vendelux uses AI to enrich these high-intent profiles with verified email addresses and LinkedIn information.
Early adopters HLTH and StableCon reported boosted attendance at recent conferences.
Founded in 2021, Vendelux secured $14 million in November 2023. Its database of over 250,000 global business events is used by corporate marketing teams to inform sponsoring and exhibiting decisions. While currently holding attendee data on a subset, Vendelux is expanding this to enable clients to pre-book meetings at events.
Open questions remain regarding data-sharing disclosures to registrants, and potential scrutiny from global regulators on this type of “data cooperative” model. While the data pool is global, stricter GDPR rules largely rule out using European attendee data.
