Vendelux Raises $50M Series B to Turn Event Attendance into Pipeline

Vendelux, a New York City startup that uses AI to help businesses predict which conferences and trade shows will generate the most pipeline, has closed a $50 million Series B round. Tribeca Venture Partners led the financing. The company’s platform ingests data on more than 250,000 B2B events globally, mapping attendee lists, speakers, and sponsors against a customer’s ideal profile. It then automates pre-event outreach so sales teams arrive with calendars already full of qualified meetings. Customers include AdRoll, Coupa, Ramp, Glean, and McKesson, among others. The round comes as in-person marketing remains one of the largest line items in B2B budgets, yet many teams still struggle to connect spend to revenue. Vendelux’s own 2026 industry report, based on input from over 120 marketing leaders, highlights the pressure to prove event ROI. The company’s tools replace the manual process of scouring organizer websites and gut-feel decisions with a data layer that tracks who will be in the room and what deals are at stake. CRM integrations push that intelligence directly into Salesforce and HubSpot, letting revenue operations teams measure attribution without spreadsheets. While the company did not detail specific plans for the new capital, the Series B is a significant step up and positions Vendelux to deepen its event database, expand its AI-driven meeting booking service, and potentially grow beyond its current vertical. In a market where field marketing and event budgets are under constant scrutiny, a platform that can show a 300 percent pipeline increase—as one case study claims—will attract attention from both buyers and investors.
