UXDX brought its community night to Warsaw, at Imaguru Startup HUB, a free evening on AI inside product teams. I co-hosted with Agnieszka Balcer-Thinlay from OLX, gave my talk on Product Build Day, then joined Szymon Trzepla and Małgorzata Wyczańska from Sanoma Learning for a panel that went where good panels go: into the messy parts, and beyond the event itself.

My big takeaway, on stage and in the panel and again in the conversations after: when product teams stop waiting on someone else to build the first version, the whole pace changes. It was a sharp room that asked real questions and stuck around after.

One honest moment I keep: someone in the room, Zenobia, looked at my who-is-in-the-room slide and asked where the developers were. She was right. Developers belong in a Product Build Day, next to PMs, POs, UX, sales, marketing and leadership. As my manifesto says, the title a person walks in with does not decide what they walk out with.

What the room took away

01

Everyone can build now, your PM too. But speed without discovery ships the wrong product.

02

Put different roles at one table with AI, and the lines blur.

03

When teams stop waiting on someone else to build the first version, the pace changes.

Two sessions

Talk

Vibe coding meets discovery

The hackathon method, and how to run one in your team. Everyone can build now, but speed without discovery ships the wrong product. Vibe code your bets, get cross-functional teams on the same page, learn before real dev time starts.

Panel

AI joined the team. What does that do to UX and dev?

An open discussion on how AI reshapes collaboration, accessibility, design quality, delivery speed, and the boundaries between roles.

With Szymon Trzepla and Małgorzata Wyczańska, Sanoma Learning. Co-hosted by Agnieszka Balcer-Thinlay, OLX.

The talk plants the seed. The build day is where people find out they can actually do it.
