Andere drücken die Schulbank, wir aber wollen in gemütlicher (und realer) Atmosphäre wieder aufeinandertreffen und einen Deutsch-Spanisch-Tandemkurs aufleben lassen. Beim einfachen Zusammenkommen und kennenlernen lässt es sich schließlich viel effektiver lernen. und Spaß haben. ...

📢 WICHTIG 📢 Diesmal organisieren wir das Treffen draußen, im Tilla-Durieux-Park gegenüber The Playce in Potsdamer Platz. Wir sitzen auf dem Gras, wo der Boden flach ist. Wenn möglich bring bitte Picknickdecken mit.

What happens when PMs stop watching engineers code — and start shipping themselves? You’ve probably heard the stories. Maybe you’ve already tried it in your own company. AI is changing how product teams build, collaborate, and ship — fast. Join us for an evening with product leaders sharing real-world experience building and shipping customer-facing features with AI, not just internal demos and experiments. We’ll talk about PMs opening PRs, non-devs contributing directly to production, and what actually changes when the whole team gets closer to the codebase. This event is designed for Product Managers and Product Leaders who want to understand how product roles, collaboration, and development processes are evolving in the AI era. **Agenda** 18:15 – Doors open for snacks, drinks, and networking 19:00 – Welcome from ProductTank Berlin 19:10 – Opening the PR is just the beginning, Dmitry Gorshkov 19:40 – What happened when we let non-devs into the codebase, Elena Berendeeva 20:10 – Networking 21:30 – Event ends Please note: - Please bring your IDs as you’ll need it when entering the venue. - The event is RSVP only: to enter, you must RSVP here on Meetup. - We'd like to capture the event with photographs for promotional purposes, such as sharing on LinkedIn after the event. If you have any concerns or preferences regarding this, please feel free to let us know beforehand. **Opening the PR is just the beginning** Dmitry will show how to go deep into the codebase as a PM and make it worth the effort. Crafting code is time consuming, so should PMs code instead of doing PM work? Absolutely. But you must come prepared. About the speaker [Dmitry Gorshkov](https://www.linkedin.com/in/dmitrygorshkov?utm_source=share_via&utm_content=profile&utm_medium=member_android) is a lead product manager at Finom, a Dutch fintech superapp for small businesses. Dmitry has shipped successful products at N26, Taxfix and Cut the Rope, among others - and has more than a decade of product management experience. **What happened when we let non-devs into the codebase** A year ago, we let PMs, designers, and QA contribute directly to our existing codebase using AI. What followed wasn’t just faster shipping – it was a quiet shift in how our team made decisions, handled ownership, and thought about their roles. This is that story. About the speaker [Elena Berendeeva](https://www.linkedin.com/in/berendeeva-elena?utm_source=share_via&utm_content=profile&utm_medium=member_android) is a PM at JetBrains who spent the last few years building 0-to-1 products – through pivots, sunsets, and a lot of uncertainty. Her most recent product is Matter, an AI prototyping tool that her team – designers, QA, and engineers – used to ship directly to production. She explores AI-native workflows and the evolving role of PMs in agentic product development.

Looking for a low-pressure way to get offline, meet new people, and actually do something fun on a Tuesday? This is a relaxed pool night in Spandau—come for a few rounds, stay for the chats, and leave with a couple of new familiar faces. **What to expect** * Casual pool games in **rotating rounds** (so everyone gets to play) — **beginners are welcome** * A friendly vibe: meaningful conversations *and* a bit of playful pool-table silliness * We **start on time** — please arrive punctually, otherwise it’s hard to fit you into the rotation **Costs** * Your own drinks + shared table costs (depending on group size) **RSVP** Please RSVP on Meetup so I can estimate how many tables we’ll need.
