What Makes a Tech Meetup Worth Coming Back To?

Imagine arriving at a tech meetup alone. You have found the venue, ordered a drink, and spotted three groups already deep in conversation. For a moment, your phone becomes the most interesting object in the room.

Where do you start?

That moment is easy to miss when you are organizing the evening. You are checking the entrance, speaking with the venue, and watching people arrive. Meanwhile, someone a few meter away is deciding whether they feel comfortable enough to stay.

After six events in six months of building The Sandbox, I want to pay more attention to that experience. We have welcomed 100+ people at our events and have 500+ registration. The next question is what makes people want to return.

Psychology offers some useful clues. Research on conversation and social connection cannot tell us exactly why someone will attend the next meetup. It can help us think more carefully about the evening we are inviting them into.

1. It feels possible to arrive alone

Walking into a room of strangers asks something of you before the first conversation even begins. You have to choose someone to approach, find an opening, and trust that your presence will be welcome.

Even afterward, your judgment of how it went may be harsher than the other person's.

In a 2018 paper, Erica Boothby and colleagues studied what they called the liking gap. Across several settings, people tended to underestimate how much their conversation partners liked them and enjoyed their company. The pattern appeared among strangers meeting in a laboratory, workshop participants, and students getting to know dorm mates. Read the study summary in Psychological Science.

The finding concerns how people judge conversations afterward. My takeaway for hosting is to make welcome visible, so newcomers have less to guess about.

A host could ask what brought someone along, then introduce them through a shared interest: one person is experimenting with an AI tool; another has been trying something similar. A regular attendee can leave space in a circle and bring a newcomer into the conversation.

Small gestures give someone an entry point. A friendly event description becomes much more convincing when a person at the door acts on it.

2. There is room to move beyond the introduction

A job title gives you a starting point. What someone is trying to figure out gives you somewhere to go.

For example, imagine a developer mentioning a side project. You could ask what they are building, then follow the detail that interests you: what surprised them during testing, which decision they are stuck on, or who they hope will use it. These are possible conversations, not accounts from specific Sandbox attendees.

Research suggests we can be too cautious about going a little deeper. In experiments by Michael Kardas, Amit Kumar, and Nicholas Epley, conversations with strangers felt less awkward and more connecting than participants expected. When participants experienced both a deeper and a shallower conversation, they felt more connected to the deeper conversation partner. The paper appeared in the Journal of Personality and Social Psychology in 2022. Read the authors' research summary.

Some of the study prompts were much more personal than I would suggest for a tech meetup. My application is gentler: leave room to discuss something that matters to the other person, and let them choose how much to share.

An easy opening about the venue or how someone found the event can do its job perfectly well. The opportunity is to follow the conversation when something interesting appears.

For more ideas, our guide to conversations at The Sandbox After Hours explores what people might take away from an exchange.

3. The setting makes conversation easier

Our fourth event was an independently organized rooftop Builder Night during a building week. More than 30 people attended, and that felt like a breakthrough.

The rooftop was part of the invitation. I cannot tell you how much the venue, timing, or theme contributed to turnout, or whether any one of them made someone return.

But choosing a place gives an organizer practical questions to answer. Can people hear one another? Can someone move between conversations? Is there somewhere to sit? Are the location, prices, and format clear before people arrive?

A beautiful setting still needs to work for the evening you want people to have. If a conversation means repeatedly shouting the same sentence, something about the setup needs attention.

The Sandbox began with the idea of tech people, builders, and curious minds meeting over a beer or another drink in a nice setting. I want the setting to help people settle in, whether they drink alcohol or not.

4. You can contribute while you are still learning

“Curious minds” has to mean something when someone walks through the door.

Someone learning to code should be able to ask a question. A developer should be able to describe an experiment that failed. A founder should be able to talk about a problem they have yet to solve.

For me, that is a hosting standard worth working toward. It means explaining unfamiliar terms when needed, making room for different levels of experience, and asking about people's interests before deciding what they can contribute.

A possible format to test is a short, optional invitation: bring something you are working on and one question you would welcome help with. Someone could share a rough demo; someone else could bring an observation from their work.

Participation should remain a choice. Listening and getting comfortable are reasonable ways to spend a first evening.

5. Familiar faces have value, even before friendship

An event does not need to produce a cofounder, customer, or close friend to have been worthwhile. There is room for the person you recognize, exchange a few words with, and are glad to see again.

Gillian Sandstrom and Elizabeth Dunn examined these more casual relationships in their 2014 research on weak ties, meaning acquaintances. Students reported more happiness and a stronger sense of belonging on days when they interacted with more classmates than usual. Further studies found associations between everyday interactions with weak ties and social and emotional well-being. Read the paper's abstract.

These findings describe associations; they do not establish that recurring meetups cause belonging or guarantee repeat attendance. They do give us a reason to value modest connections.

For The Sandbox, I would like returning to mean having a little more to pick up where you left off. Perhaps you remember what someone was testing and can ask how it went. Perhaps you now recognize a face at the entrance.

A community should have room for relationships that grow slowly.

As those connections develop, regulars also have a role in keeping conversations open to the next newcomer.

6. The connection has somewhere to go afterward

A good evening can leave a small piece of unfinished business: a tool to share, a question to revisit, or a project someone offered to look at.

That is the kind of continuity I want to explore through new event formats and a WhatsApp group. A useful next step could be sharing the resource you mentioned, asking for feedback on a specific problem, or arranging to continue a conversation at the next gathering.

These are possibilities for how the community could develop. We still need to learn what people would find useful and how they would like to participate.

The same care applies to the event itself. Clear information about costs, the format, and a sponsor's role helps people decide whether the evening suits them. After navigating venue deposits and questions about charging, I want that clarity to be part of making The Sandbox sustainable.

What would bring you back?

Attendance tells us how many people came. Understanding the experience means asking them what happened once they arrived.

For the next stage of The Sandbox, these are the questions I want us to keep asking:

• Did you feel welcome, especially if you came alone?
• Was there a conversation you were glad you had?
• What would you change before the next event?

Even a good evening can be followed by a scheduling conflict, so repeat attendance will never tell the whole story. But listening to those answers can give us something concrete to improve.

If you have joined us, what is one thing that would make you want to come back?

And if you are looking for tech people, builders, and curious minds to meet in Saigon, join The Sandbox. Help us shape the next evening.
