Vendelux

Vendelux calls itself an event intelligence platform, and the label is more literal than most marketing copy. It maintains a proprietary database of more than 250,000 B2B events - conferences, trade shows, summits and meetups - and, crucially, data on the people and companies expected to attend them. The pitch to a go-to-market team is direct: tell us who your customers are, and we will tell you which of the year's 250,000 events they are actually walking into.

That inversion - knowing who will be in the room before the room fills up - is the core of the product. Instead of choosing events on reputation or last year's gut feel, a marketing leader can rank next year's calendar by how many target accounts actually register. Instead of hoping to bump into a buyer on the show floor, a sales rep can have the meeting booked three weeks in advance. And instead of reporting a vague "event ROI" number nobody believes, a team can tie specific closed deals back to specific events inside Salesforce or HubSpot.

The company was co-founded by Alex Reynolds, its chief executive, and Stefan Deeran, its chief operating officer. The two met at Shutterstock, where they built a business unit together and repeatedly hit the same wall: no reliable data on which events were worth the travel. They left to build the missing data layer themselves. Reynolds, a former Bain & Company consultant, has described the early phase of the company as a move "from intropreneur to entrepreneur" - the idea being that the value of the connections you make at events only compounds if you can find, prioritize and remember them at scale.

By 2026 the thesis had attracted serious capital. A $14M Series A led by FirstMark Capital in late 2023 was followed, in July 2026, by a $50M Series B led by Tribeca Venture Partners, with HubSpot Ventures, FirstMark and Cervin Ventures joining. That brought total funding to roughly $71M and put a well-funded bet behind a simple proposition: in-person marketing does not have to be unmeasurable. It was just under-instrumented.

It is easy to mistake Vendelux for the software that runs events. It isn't. Platforms like Cvent and Bizzabo help organizers host and manage conferences - registration, badges, agendas. Vendelux sits one layer up, on the side of the companies deciding whether to show up at all. Its raw material is attendee intelligence: who is going, whether any of them are your buyers, and what happened to the pipeline afterward.

Sales-intelligence tools such as ZoomInfo and 6sense overlap at the edges, since teams sometimes use them to research who might attend an event. But those systems were built for general prospecting, not for the specific, time-boxed problem of a trade show calendar. Vendelux combines a purpose-built event database, ICP matching, meeting booking and CRM-native attribution into a single workflow.

The most honest way Reynolds frames the competition is that the real alternative is not another vendor - it is the spreadsheet. For most companies, the incumbent system for event planning is a marketer's manual tracker and institutional memory. Vendelux's bet is that a 250,000-event dataset and AI agents beat a spreadsheet and a hunch, and that once a CFO sees pipeline tied to specific events, the spreadsheet doesn't come back.

In 2025 the company widened its footprint with a free Delegate Marketing Platform aimed at the other side of the market: the organizers themselves. By giving them AI agents and access to a network of marketers who control more than $50 billion in sponsorship budgets, Vendelux positioned itself as a two-sided layer - useful to the companies buying booths and the events selling them.

Vendelux is a B2B SaaS business. Its core revenue comes from subscriptions sold to go-to-market, marketing and sales teams, priced around access to the event intelligence database, attendee matching, and the meeting and CRM attribution workflows that sit on top of it. The value proposition is squarely economic: for teams spending heavily on events, the platform's cost is meant to be small next to the sponsorship dollars it helps allocate and the pipeline it helps prove.

The 2025 Delegate Marketing Platform added a second side to the model. Offered free to conference organizers, it draws the supply side of the events economy onto Vendelux and connects them with the network of marketers and sponsors already on the platform. That two-sided design - buyers of event presence on one side, sellers of it on the other - is what the company means when it describes itself as an operating system for event intelligence rather than a single-purpose tool.
