Vendelux raised $50 million because corporate event spending still has one basic problem: too much money goes out before anyone can prove what came back.
Vendelux just closed a $50 million Series B. Tribeca Venture Partners led the round, with S3 Ventures, Pelion Ventures, HubSpot Ventures, FirstMark Capital and Cervin Ventures also joining. Business Insider reported the raise on July 8, and said the New York startup has now raised $71 million since Alex Reynolds and Stefan Deeran, two former Shutterstock alums, founded it in 2021.
If your marketing budget has a line item for conference sponsorships, you already know the problem Vendelux is chasing. You sponsor a booth, fly people out, print the banners and hope the right buyers walk past. Six weeks later, someone asks what came from it. The answer is often a spreadsheet, a few scanned badges and a sales team that has already moved on.
That isn't good enough. Not at this scale.
Vendelux's answer is a database, not a dashboard trick. The company says its platform uses AI and proprietary data from more than 250,000 events around the world to help B2B companies decide which conferences, dinners and trade shows are worth attending. It also plugs into customer relationship management systems so teams can check whether a dinner, booth or meeting actually led to pipeline. That last part matters, because the old version of event marketing asked finance teams to trust vibes dressed up as brand awareness.
Business Insider reported that Vendelux has more than 250 customers, including Ramp, ElevenLabs, Vercel, Glean, GitLab, DocuSign and Intel. Those names tell you where the company is trying to live. This isn't a tool built only for a founder going to one SaaS conference with a backpack and a nervous pitch. Reynolds told Business Insider the bigger opportunity is enterprise, the companies that send large teams to multiple events and then need to defend the cost afterward.
The timing helps. According to the same Business Insider report, a first-quarter Forrester survey of 654 marketing decision-makers found that organizations spend more than one-fourth of their marketing program budgets on events on average. That's a large enough slice of budget to attract scrutiny. It should.
The spend came back before the measurement did
This is Vendelux's opening. In-person B2B events came back after the pandemic faster than many finance teams got comfortable with them again. Tech companies still want face time with buyers, partners and investors: Cannes Lions, SaaStr, Dreamforce and the private dinners that circle them haven't disappeared into a Zoom calendar. The event circuit came back. Measurement didn't follow.
Click a search ad and you can see cost per lead in seconds; sponsor a trade show and you're arguing from memory instead - who stopped by, who seemed serious, who promised to follow up, who never called back. Vendelux is betting that marketers are done making that argument with loose evidence. You can call that unglamorous software. Good. Some of the best business software is just the thing that finally puts a number on a cost everyone had learned to tolerate.
The company had already raised a $14 million Series A in 2023, according to Business Insider. This new round is bigger, and the plan is more operational than theatrical. Vendelux plans to expand its enterprise products and put more money into marketing, all while building tools that show return on investment from events. The company has 85 employees and plans to roughly double that headcount this year.
The hard part is trust
Some skepticism is fair. Vendelux's event data may be deep, but event attribution is messy by nature. A buyer might meet a salesperson at a private dinner, read three emails, talk to a peer and then sign a contract months later. No software should pretend that one touchpoint explains the whole decision. That's how marketing tools lose credibility.
But here's the thing: imperfect measurement is still better than no measurement when the budget is this large. If a company sends people to ten events a quarter, it needs to know which two are consistently producing real conversations and which ones are just expensive habit. Vendelux doesn't have to solve the full mystery of human buying behavior to be useful. It has to make the next event decision less blind than the last one.
Competition will be part of that test. Business Insider noted that Vendelux faces companies such as Jifflenow and Chili Piper, which help teams book meetings around events. Vendelux's argument is that meeting logistics are only one layer. The more valuable layer is knowing where to go in the first place, who will be there and whether past attendance turned into revenue.
Reynolds and Deeran are making a plain bet: event marketing won't shrink back into a side channel, but it will have to answer harder questions. Fifty million dollars says Tribeca Venture Partners agrees. Now Vendelux has to prove that the trade show floor can be measured without pretending it's a Google ad.
