Lanyard sponsorship is the exclusive right to brand the lanyards worn with attendee badges. Because nearly every attendee wears one all event, in every aisle, session, and photo, it delivers constant, event-wide brand exposure. It's a classic single-item sponsorship: simple, visible, exclusive by nature, and quick to sell.

A large language model (LLM) is an AI system trained on huge amounts of text so it can read, write, and answer questions in plain language. Tools like ChatGPT and Claude are LLMs. For event teams, they're the engine behind features like natural-language search across attendee and exhibitor data.

A last-chance campaign is the final promotional push in the days before an event or before a deadline such as a price increase or registration close. It concentrates urgency messaging — deadlines, scarcity, what latecomers will miss — on people who showed interest but haven't registered, and it typically converts disproportionately well.

Last-touch attribution is a model that gives 100% of the credit for a conversion or deal to the final marketing interaction before it happened. It's simple to implement and easy to read, but it ignores every earlier touch — which tends to make trade shows look less valuable than they are.

Lead capture is the process of recording a prospect's contact details and conversation context at an event so the exhibitor can follow up afterward. It covers badge scanning, manual entry, business card collection, and form fills, plus the notes and qualifiers that make the record useful to sales.

Lead decay is the loss of a lead's value as time passes without follow-up. After an event, a prospect's memory of your conversation, their sense of urgency, and their openness to a call all fade — often within days — so the same lead is worth less each week it sits untouched.

Lead guarantee is a contractual commitment that a sponsorship or exhibiting package will deliver a minimum number of leads — scanned contacts, content downloads, or qualified enquiries — with a defined remedy if it doesn't, such as a refund, credit, or extended benefits. It converts a visibility promise into a performance one.

Lead handoff is the transfer of captured event leads from the team that collected them — booth staff, marketing — to the people who will work them: sales reps or SDRs. A clean handoff moves each lead with its context, qualification notes, and agreed next step intact, within days of the show closing.

Lead qualification at events is the process of sorting captured leads by how well they fit your target customer profile and how ready they are to buy. It happens ideally at the booth during the conversation, using a few standard questions, and determines who gets fast, personal follow-up.

Lead retrieval is the system exhibitors use to capture attendee contact details at an event, typically by scanning badges with a rented device or a mobile app. When an attendee's badge is scanned, their registration data — name, company, title, email — is delivered to the exhibitor's lead list.

Lead scoring is a system for ranking leads by assigning points based on fit (job title, company size, industry) and behavior (booth visits, demo attendance, email engagement). Leads that cross a set threshold get routed to sales; the rest stay in marketing nurture until their score rises.

Leaderboard (events) is a ranked, visible list of participants in an event's gamification programme, ordered by points earned from actions like stand visits, session check-ins, and connections made. Displayed in the app and often on venue screens, it adds public competition to the game's private rewards.

Lessons-learned review is a structured session held after an event where the team examines what worked, what failed, and why — across operations, marketing, sales, and content — and converts the answers into documented changes for the next edition. It's the mechanism that turns experience into institutional memory.

A limited partner (LP) is an investor in a venture fund (pension, endowment, family office, or individual) rather than a direct startup investor — sometimes present at industry events.

Live captioning is the real-time display of a session's spoken words as on-screen text, produced by human stenographers or AI speech recognition. It serves deaf and hard-of-hearing attendees first, but also helps non-native speakers, people at the back of loud halls, and anyone watching the stream with sound off.

Live data is event information that updates as things happen — check-ins, session scans, meeting confirmations, booth traffic — rather than arriving in a report days later. It gives organizers a current picture of the show floor while there's still time to act on it during the event itself.

Load-in schedule is the timetable governing when each exhibitor, contractor, and freight shipment may enter the venue to build the show, typically sequenced by booth size, location, and build complexity. It converts finite dock capacity and hall time into ordered slots so hundreds of parties don't arrive at once.

Loading dock is the venue's freight entrance — the bays, ramps, and doors where trucks deliver and collect exhibition freight. Dock count, door dimensions, and vehicle access determine how fast a show can load in and out, making the dock the physical bottleneck behind every move-in schedule.

Lookalike modelling is a technique that finds new prospects who resemble your best existing audience. You supply a seed — say, your most engaged buyers or highest-renewing exhibitors — and the model searches a larger population for people or companies with similar characteristics, giving audience acquisition a data-driven starting point.

A lost-reason taxonomy is a controlled list of why deals are marked lost — budget, timing, competitor show, category mismatch, pricing, no decision — so patterns can be measured.
