The trade show floor is one of the last places in B2B selling where a CFO has to take the marketing team's word for it. Badges get scanned, drinks get poured, a few business cards survive the flight home, and somewhere in the next quarter a deal closes that someone, somewhere, attributes to the booth in Hall C. Vendelux, a New York company founded in 2021 by Alex Reynolds and Stefan Deeran, is building the spreadsheet that finally settles the argument.
The pitch is straightforward. Vendelux indexes more than 250,000 B2B events and gives go-to-market teams attendee intelligence, pre-booked qualified meetings, and CRM attribution against the resulting pipeline [Vendelux]. Customers pay in meeting credits and lead credits, with pricing that scales by team size and event count [Vendelux]. The wedge is not the AI itself, which is now table stakes, but the size of the underlying event graph. If you want to know which of your ideal customers will be at Epicor Insights 2026 or the IEEE Aerospace Conference, Vendelux already has the attendee list pulled together [Vendelux].
The bet
Reynolds, who previously ran Platform Solutions as a VP and GM at Shutterstock [Crunchbase], and Deeran, the company's COO [Forbes, Feb 2023], are betting that events are the most expensive marketing line item that nobody can defend with a number. Demand-gen leaders are asked to deliver pipeline; events have historically operated outside the system [Vendelux]. By plugging event data into the same CRM dashboards where Salesforce opportunities live, Vendelux is trying to convert a gut-feel budget into a measurable channel. The company says teams using the product report six times more meetings booked than manual outreach, and a 300 percent year-over-year increase in late-stage pipeline tied to events [Vendelux, Vendelux Blog]. Those are company-disclosed figures, useful as a directional claim about what good deployments look like.
Why it could be big
The in-person event budget did not die during the pandemic, it paused and then came back larger. FirstMark led a $14 million Series A into Vendelux in November 2023, on top of a $2.4 million seed in early 2022 [TechCrunch, Nov 2023; Crunchbase, Jan 2022]. The thesis FirstMark is buying is that the post-pandemic rebound in conferences, summits, and customer advisory boards is structural rather than cyclical, and that the marketing team running a $40,000 booth at a SaaS conference is desperate for the same pipeline math their digital ads team has had for a decade.
Seed (Jan 2022) | 2.4 | $M
Series A (Nov 2023) | 14.0 | $M
Total disclosed | 16.4 | $M
The addressable spend here is genuinely large. A single enterprise software vendor can spend seven figures a year on a handful of flagship conferences before counting travel, swag, and the sales reps flown in to staff the booth. If Vendelux can credibly attribute even a slice of resulting pipeline, the ROI conversation gets easier and the renewal becomes close to automatic. Reynolds has made the case in Forbes that generative AI will make in-person events more valuable rather than less, because the marginal cost of a competent-sounding email has collapsed and the marginal value of a real handshake has not [Forbes, Oct 2023].
The team and traction
Reynolds, the co-founder and CEO, brings event marketing and business development experience from Shutterstock [Frontlines Podcast; Crunchbase]. Deeran, co-founder and COO, has been the public face on AI-for-events thought leadership since early 2023 [Forbes, Feb 2023]. The current team includes data engineering hires such as Claudio Rodriguez Valdes [LinkedIn, 2026], which matters: the moat here is the quality of the event and attendee graph, and that is a data engineering problem before it is a model problem. The customer-facing pages list named enterprise events through 2026, suggesting the content and data pipeline is being maintained at depth rather than scraped once and forgotten.
The honest counterfactual
What bears will say is that the event-tech category is crowded and that incumbents like RainFocus and Bizzabo already sit inside the workflow of the conference organizer, which gives them privileged access to the registration data Vendelux has to assemble from the outside. There is also genuine cyclical risk: if a 2026 marketing budget tightens, the event line is one of the first to get cut, and Vendelux's seat count would compress with it. What bulls answer is that Vendelux is selling to the buyer of the booth rather than the seller of the booth, which is a different and arguably larger market, and that CRM-grade attribution is precisely the feature that protects an event line item when the CFO comes asking [TechCrunch, Nov 2023]. The six-times-meetings figure is a marketing claim, but the structural argument behind it, that manual conference prep is genuinely terrible, is one any field marketer will confirm unprompted.
What to watch
The next twelve months should tell us whether Vendelux is a feature or a category. Watch for a Series B, which would typically land 18 to 24 months after the November 2023 Series A, and watch for named enterprise logos in the customer stories section, which is currently lighter than the product depth would suggest. A formal integration with Salesforce or HubSpot at the AppExchange tier would be a strong signal that the attribution claim is being taken seriously by the systems of record. The 2026 conference calendar, already mapped out on Vendelux's own site, is the live demo.
Back of envelope: a mid-market SaaS company spending $1.5 million a year on twelve flagship events, at a roughly $25,000 to $60,000 annual Vendelux contract (estimated, based on team-size pricing tiers [Vendelux]), is paying two to four percent of event spend for the measurement layer. If that layer recovers even ten percent of previously wasted booth time, the math closes on the first renewal call. Across a few thousand such buyers, that is a credible nine-figure ARR opportunity.
The incumbent Vendelux has to beat is Bizzabo, which owns the event organizer's stack and has been pushing into attendee engagement and analytics from that side of the table. Vendelux is approaching the same pipeline number from the exhibitor's seat. Whichever side proves it can hand the CFO a clean attribution report first gets to define the category.
