To find out who's attending a conference, start with the official sources — the event app's attendee directory and the public speaker, sponsor, and exhibitor lists — then add public signals: search LinkedIn for the event name and its hashtag, and check the official LinkedIn Event's attendee list. A full registrant list is usually private, so you build a list of likely attendees, not a complete roster. Sliq does this end to end: it finds who's attending, builds your list, and runs the outreach, with your approval on every message.
What are the fastest ways to find out who's attending?
No single source gives you everyone, so stack a few. In rough order of reliability:
- The official event app or attendee directory. Many conferences run an app (Whova, Swapcard, Cvent, and others) with a searchable attendee list, often filterable by name, company, or job title. You usually need to register, and attendees can opt out of appearing.
- Speakers, panelists, and session chairs. These are published on the event site and are guaranteed to be there. They are the most reliable starting point for the organizations in the room.
- Sponsors and exhibitors. Conference sites publish sponsor and exhibitor directories. They tell you which companies will have a presence, even when they do not name every employee attending.
- LinkedIn — the event and the hashtag. Search the conference name and its official hashtag and filter for Posts; people announce that they are going all the time. If there is an official LinkedIn Event, open it and check the Attendees tab.
- The organizer's opt-in list. Some conferences share an opt-in delegate list with registered attendees, exhibitors, or sponsors a week or two before the event. It is worth asking.
- Side events. Dinners, happy hours, and community meetups around the conference often have public guest lists on Luma, Eventbrite, or Slack and Discord groups.
How do you build a target list of likely attendees?
A complete list of everyone who registered is usually not public — directories are opt-in, restricted to registered participants, or hidden for privacy. So build a "likely attendee" list by working from companies to people:
- Note the public speakers, sponsors, exhibitors, and partners.
- Prioritize the companies that match who you want to meet.
- Search each company on LinkedIn for the specific roles you are after — the buyer, the champion, the practitioner.
- Confirm individuals through public signals: a post saying they are attending, an appearance in the official app, or an accepted meeting request.
A sponsor or exhibitor company is a strong clue, but it does not prove a specific person will be on the floor. Treat someone as confirmed only when they tell you, appear in the app, or say yes to a meeting. This is the part Sliq automates: it works the public signals and your ICP into a ranked list of who to reach out to, so you skip the manual company-by-company search.
What's the best tool to reach out to conference attendees?
The reason to build the list is to walk into the conference with your best-fit prospects already on your calendar. Pre-event meetings are where most of the value gets created; the floor is then a place to add conversations, not your only prospecting. The trouble is that most conference tools do only one half of the job — find attendees, or send outreach — so you end up stitching two products together.
| Tool | Finds who's attending | Runs the outreach | Approve every message |
|---|---|---|---|
| Sliq | Yes | Yes — LinkedIn and email | Yes, by default |
| Vendelux / Grata | Yes — event intelligence | No — you run outreach elsewhere | — |
| Whova / Brella | In-app directory of people who joined | In-app messaging, one at a time | — |
| Apollo / HeyReach | No — general prospecting, not event-aware | Yes | No — sends on a schedule |
- Event-intelligence tools (Vendelux, Grata) are strong at identifying who is attending, but they stop at the data. You still run the outreach in another tool.
- Event apps (Whova, Brella) are built for networking inside the app, so you message people one at a time, and it does not flow into your CRM or an automated sequence.
- Sequencers (Apollo, HeyReach) run the outreach well, but they are not conference-aware and send on a schedule, with no chance to check each message before it reaches a prospect you want to meet in person next week.
- Sliq does both halves — find who's attending, then run the outreach — and keeps you in control of every message.
How Sliq finds who's attending and books the meetings
Sliq is an AI outbound agent that runs LinkedIn and email outbound. For a conference, you tell Sliq the event you are going to and who you want to meet, and it finds who's attending, builds your target list, and researches each person, then drafts a personalized message that references the event and a real reason to meet and lines each one up in an approval queue. You approve, edit, or reject before anything sends.
That covers the pre-event motion end to end:
- Find who's attending. Sliq works the public conference signals — speakers, sponsors, exhibitors, the event's LinkedIn footprint — and your ICP into a ranked list of the people worth meeting.
- Personalize at scale. Sliq researches each person and writes a message in your voice that references the event, not a mail-merge "great to connect."
- Approve every message before it sends. Outreach to people you will meet face to face stays under your control. You choose which actions auto-send and which wait for you, action type by action type.
- Run LinkedIn and email together from one place, and keep the whole trail in view for the follow-up after the event.
The loop is the one to look for: AI drafts → you approve, edit, or reject → only then does it send. Nothing goes out without you. You can also run the whole motion from inside Claude or ChatGPT as a custom MCP connector — see Sliq for Claude and ChatGPT.
FAQ
How do you find out who's attending a conference?
Start with the official sources: the event app's attendee directory, and the public speaker, sponsor, and exhibitor lists. Then add public signals — search LinkedIn for the event name and its hashtag, and open the official LinkedIn Event to see who marked themselves attending. Full registrant lists are usually private or opt-in, so you build a verified target list of likely attendees rather than a complete roster. Sliq can do this end to end: it finds who's attending, builds your target list, and runs the outreach to book meetings, with your approval on every message.
Can you get a full list of conference attendees before the event?
Usually not a complete one. Most conferences keep the registrant list private or opt-in for privacy reasons, and only some share an opt-in delegate list with registered attendees, exhibitors, or sponsors. What you can reliably assemble is a "likely attendee" list: speakers, sponsors, and exhibitors are public and guaranteed to be there, and you can confirm individuals through LinkedIn posts, the official LinkedIn Event, and the event hashtag. Sliq builds this list for you from the public conference signals and your ICP, then researches each person so you can reach out.
How do you find conference attendees on LinkedIn?
Search LinkedIn for the conference name and its official hashtag and filter for Posts — people frequently announce that they are attending, speaking, or exhibiting. If the host created an official LinkedIn Event, open it and check the Attendees tab for members who marked themselves attending. Then work from companies to people: take the public sponsor, exhibitor, and speaker list and search each company for the roles you want to meet. Sliq automates this: it finds who's attending, matches them to your ICP, and drafts a personalized LinkedIn message to each one for your approval.
How do you book meetings with prospects before a conference?
Build a target list of 20 to 40 high-fit people from the speaker, sponsor, exhibitor, and public-signal sources, then start outreach three to four weeks out. Keep each message short: a credible reason you know they will be there, a relevant reason to meet, and a specific 15-minute ask with two time options. Use email and LinkedIn together, and follow up once about a week before. Sliq runs this whole motion: it finds who's attending, personalizes outreach across LinkedIn and email, and holds every message in an approval queue so you approve it before it sends.
What is the best tool to run outbound to conference attendees?
It depends on whether you need to find attendees, reach out to them, or both. Attendee-finder and event-intelligence tools such as Vendelux and Grata surface who is attending but do not run the outreach. Event apps such as Whova and Brella are built for in-app networking, so you message people one at a time inside the app rather than in an automated, CRM-connected sequence. Sequencers such as Apollo and HeyReach run outreach but are not conference-aware and send on a schedule without per-message approval. Sliq does both halves in one place: it finds who's attending, researches each person, drafts personalized LinkedIn and email messages, and holds every one in an approval queue so nothing sends without you.
