How I organised a record-breaking .NET meetup in Wrocław

Our previous Wroc.NET registration record was 165 people, set at our 100th meeting nine years ago. On October 20, we broke it: 171 people registered for meeting 171, with another 34 on the waiting list. That was 205 people wanting to join us at Pub Wędrówki in Wrocław.

I first came to Wroc.NET as a participant well over a decade ago. In April 2025, I joined the organising team with a clear goal: help the group grow again.

The months since then had gone into finding a strategic sponsor, securing a venue and building a process for inviting speakers and working with partners. As in previous months, I was organising the October meeting from start to finish.

Taking a chance on October

For a while, though, we were worried about whether people would come. A .NET developer conference in Warsaw fell on the same date. We decided to take the risk.

Then devstyle, our strategic partner, asked for October. We already had a programme agreed: a joint session by Hleb Sukrystsik and Łukasz Hałas, followed by a session by Melchior Kozar.

Before we could make room for the new programme, those three speakers would have to move their talks. I spoke with them, and they kindly agreed. They will speak in the coming months. Without their flexibility, this October edition would not have happened.

By September 28, Maciej Aniserowicz, the devstyle team and I were working on the announcement. There were 22 days left until the meeting.

The new programme paired AI in an established product with programming using agents. Both presentations would lead into a discussion with the audience, continuing the format I wanted to keep after our September panel.

That needed more time than a normal evening. With the pub owner, I agreed on an earlier start at 18:00 and seating for the meeting. Speaker materials and artwork also had to be ready for the announcement.

Then the places ran out

Devstyle sent its newsletter. Less than half an hour later, all 120 places were taken. We had been worried about competition for the audience. Now the waiting list was growing.

By the time it reached 60, I was back in conversation with the venue owner and the other organisers about letting more people in. The speakers and devstyle’s reach had brought more interest than our initial booking limit could accommodate.

There were still the same walls and the same amount of seating. We looked at the available space and how many registered participants usually attend before agreeing on more bookings. After checking the proposal with Maciej, I raised the limit and asked people to cancel early if their plans changed.

A full room on October 20

On October 20, the new registration record was in my opening slides. In front of me was a full room. After months of work on Wroc.NET and weeks preparing this particular evening, I was there to open meeting 171.

For Maciej, it was a return to the stage after more than six years away. In his vlog after the meetup, Maciej rated the experience nine out of ten. He also said he and Jakub Kubryński were already planning visits to more cities.

After both presentations, the conversation continued between the speakers and the audience in the panel. Starting earlier had left time for that part of the evening too.

We’ll announce the next meeting shortly, but you can already preview the programme for November 17, 18:00, Pub Wędrówki. Expect Piotr Gankiewicz on Apache Iggy performance, followed by a panel on when .NET is enough and when Rust makes sense.

The original speakers gave us flexibility, devstyle brought a strong programme and promotion, and the other organisers helped make the evening work. I am grateful for their part in it. Seeing a full room and a new registration record made me proud of the work I had put into Wroc.NET since April 2025.

Recently, I rebuilt the group’s website and recovered its history. Now I had organised a meeting that belonged in that archive as the one that broke a nine-year record. It feels great to help write the history of a community I first got to know from the audience.
