Virtual Conference Networking: Recreating the Hallway Track Online
By Let's Mingle · Published
Ask people what they remember from an in-person conference and most will name a conversation, not a keynote. Someone they met in the coffee line, a speaker they cornered after a talk, a table of strangers who turned out to work on the same problem. That is the hallway track, and it is the part most online conferences quietly drop. This guide covers how to rebuild it: where the conversations happen, how to seed them, and when to schedule them so people actually show up.
Why the hallway track disappears online
Most virtual conference platforms are built to deliver sessions, and they do that well. What they rarely do is let attendees drift into conversation the way a hallway does. The hallway works because of three things that are easy to lose online:
- You can see the room. You notice a cluster of people near the coffee, someone you recognize, a speaker standing alone for a moment.
- Joining is cheap. You walk over and listen. If it is not for you, you walk on. Nobody needs to approve it.
- Many conversations run at once. Two hundred people in a foyer are not in one conversation. They are in forty.
Session chat gives you none of those. It is one stream, everyone talks over each other, and the person you wanted to speak with is a username scrolling past. Assigned breakout rooms fix the "many conversations" part but remove choice and visibility: you are placed somewhere and cannot see what is happening next door. We wrote more about this pattern in why most virtual networking events fail.
Run a mingling space alongside your session platform
You do not need to replace your conference platform. Keep the sessions where they are and add a separate space that exists only for conversation. Think of it as the foyer outside the auditorium.
The requirements for that foyer are simple:
- Attendees can see who is there and who is talking with whom.
- They can join any conversation themselves, and leave it, without asking.
- Many small conversations can run in parallel.
- Organizers can speak to the whole room when they need to, without pulling people out of their conversations.
Let's Mingle is one tool built around exactly this. Everyone opens the same link in a browser on desktop or mobile, sees the whole room, and clicks a face or a group to join that conversation immediately. Clicking another group moves you across, and the people you left carry on. Cameras and microphones start off, and switching conversations never turns your mic on, which matters at a conference where people are often listening from an open-plan office. You can walk around the demo room to see how it feels before planning around it.
Whatever tool you use, put the link everywhere attendees look: the agenda, the session platform, reminder emails and the closing slide of every talk.
Structure the room with topic groups per track
An empty room with 150 people and no structure tends to produce a few loud groups and a lot of hovering. The fix is the same as at a physical event: give people a reason to stand somewhere.
Create one standing group per track or theme, named so people know what they will find. In Let's Mingle these are permanent groups: hosts create them in advance, they stay in the room until a host deletes them, and anyone can join. Good names are specific:
- "Platform engineering track"
- "Design systems and tooling"
- "First-time attendees"
- "Hiring and looking"
- "Regional: Europe / Asia-Pacific / Americas"
A few principles that hold regardless of tool:
- Match the groups to the agenda. If a track ends at 11:30, its group should be the obvious place to go at 11:31.
- Include one group for newcomers. First-timers are the people most likely to bounce, and the least likely to walk into a group of regulars.
- Do not create too many. A group needs at least three or four people to feel alive. For 100 concurrent attendees, six to ten standing groups is plenty. Attendees can still start their own unnamed conversations around them.
- Leave space for drift. Some of the best conversations happen between two people who left a group together. Let the room have open floor as well as tables.
Groups work best at three to five people. When one grows past seven or eight, it naturally splits as people peel off, and that is fine. Encourage it in your opening announcement: "If a group gets big, start a new one next to it."
Add speaker office hours
The single most valued hallway moment is the few minutes after a talk when you can ask the speaker a follow-up question. Online, that moment usually becomes a rushed Q&A or nothing at all.
Give each speaker an office hours group in the mingling space, named for them and their talk, for example "Office hours: Priya on edge caching". Then:
- Schedule it right after their session, for 20 to 30 minutes. Put the time in the agenda next to the talk.
- Ask the speaker to end their talk with the link and a line like "I'll be in the hallway for half an hour, come and find me."
- Brief speakers on the format. It is a conversation, not a second presentation. Small groups, people coming and going, no slides.
- Have a host or volunteer drop in first so the speaker is not alone when they arrive.
Because everyone in the room can see who is in which group, office hours also become discoverable to people who missed the talk. Someone wandering through sees six people around a speaker and joins out of curiosity, which is precisely how it happens in a real hallway.
Time the hallway around the agenda
Most networking sessions at virtual conferences fail on timing, not format. A two-hour "networking lounge" at 3 p.m. on day two, competing with three sessions, will be empty. A hallway that is open whenever people are naturally between things will be full.
Leave real breaks
Online agendas tend to pack sessions back to back because there is no room to walk between. Put the walking back. A 15-minute break between blocks and a 30 to 45-minute lunch break give the hallway something to fill.
Keep the space open all day
The point of a hallway is that it is always there. Open the mingling space before the first session and leave it open until well after the last. Quiet periods are fine. Space links in Let's Mingle are reusable, so the same link can serve all days of a multi-day event.
A sample day
Here is how a single conference day might look with the hallway built in.
| Time | Sessions | Hallway |
|---|---|---|
| 08:45 | Space opens; hosts in "First-time attendees" group | |
| 09:00 | Opening keynote | Quiet |
| 09:45 | 15-minute break; keynote speaker office hours begin | |
| 10:00 | Track sessions, block 1 | Office hours continue until 10:15 |
| 11:00 | 20-minute break; track groups fill up | |
| 11:20 | Track sessions, block 2 | Block 1 speaker office hours |
| 12:20 | 45-minute lunch; host broadcast at 12:25 to point people to groups | |
| 13:05 | Panel | Quiet |
| 14:00 | Track sessions, block 3 | Panel speakers' office hours |
| 15:00 | 20-minute break | |
| 15:20 | Closing keynote | |
| 16:00 | Social hour: track groups renamed for informal topics | |
| 17:00 | Space stays open for stragglers |
The 16:00 social hour is often the busiest slot: people have heard talks and no longer need to rush back.
Hosting the hallway during the event
A hallway with no hosts tends to stall in the first hour. You do not need many, but you need some.
Assign hallway hosts
Plan for roughly one host per 25 to 40 people in the space at peak. Their job is to:
- Greet people who are standing alone and bring them into a group.
- Keep the newcomers group going, especially early in the day.
- Spot speakers arriving for office hours and make sure someone is there.
- Notice when a group has become a monologue and gently open it up.
Let's Mingle supports several hosts with equal powers, so you can split the room between them. Hosts can also ban someone who is disrupting the space, which you will rarely need but should know how to do.
Use the room-wide controls sparingly
At a physical conference, someone rings a bell or makes an announcement when the next session starts. Online you need the equivalent. The host panel in Let's Mingle has Broadcast audio, Broadcast video, Message everyone and Announcement; broadcasting speaks to the whole room without moving anyone out of their conversation. See the help page for how each works.
Good moments to use them:
- Five minutes before sessions resume: "Track sessions start in five minutes, links are in the agenda."
- At the start of lunch: a short welcome and a pointer to the track groups and office hours.
- When a speaker arrives for office hours: a one-line message naming the group.
Keep broadcasts short: each one interrupts every conversation in the room. Three or four a day is about right.
Respect people who want to listen
Not everyone wants to talk. Say in your welcome message that listening in is welcome. In Let's Mingle, people can also set themselves to Focus, visible but not interruptible by voice, or Away when they step out.
Planning checklist
Before the event:
- Decide on your track groups and newcomer group, and create them in advance.
- Add speaker office hours to the published agenda, next to each talk.
- Brief speakers and give each one the hallway link for their final slide.
- Recruit and brief hallway hosts, with a rough rota for the day.
- Put the hallway link in every reminder email and in the session platform.
If you are expecting a very large crowd in the hallway at once, get in touch with us before the event. Comfortable room sizes for very large gatherings are still being measured during the beta, and we would rather plan it with you than have you find the limit live.
For formats that need more structure than a hallway, such as timed one-to-one rounds, see our guide to virtual speed networking. For a standalone event built entirely around conversation, see how to host a virtual networking event.
The hallway is part of the program
Virtual conference networking works when organizers treat the hallway as part of the program rather than an afterthought. Give it a place people can see, give it structure through track groups and speaker office hours, and give it time by leaving real breaks in the agenda. Then staff it with a few hosts who keep it warm. Do those four things and attendees will leave with what they leave in-person events with: the names of a few people worth talking to again.
