📅 Wednesday, December 3, 2025 – #27 ProductTank: Stop Talking, Start Shipping [Best for Product Managers, UX Researchers] [FREE]
After a period of dormancy, ProductTank Warsaw is back—this time under fresh leadership, with the same community-driven spirit and a renewed focus on real-world, applicable product insights. The relaunch event, titled “Stop Talking, Start Shipping”, will spotlight how product managers in Warsaw are applying AI tools not in theory, but in daily product workflows. This edition features two deeply experienced practitioners—Marek Trawiński of XTB and Michał Krajewski of GOG.com—who will share concrete case studies from their own AI-powered product development strategies.
The evening is hosted at BEC Financial Technologies (23rd Floor, Emilii Plater 53), starting at 18:00. The event includes two 30-minute talks with Q&A, opening remarks from ProductTank and BEC, a mid-event networking break, and a final social session until 21:00. Snacks are provided, and the meetup is free to attend, with RSVP via Meetup required. The talks will be held in English, and the event is open to the international product community.

Speaker 1: Marek Trawiński
With over a decade in UX leadership and more than 150 digital product deployments across Europe, Marek currently heads research at XTB. In his talk, Marek unpacks a comparative study of synthetic personas vs. real users. You’ll learn:
How to build digital twins using credible tools
Which research phases benefit from AI-generated insights—and which don’t
Cost/time benefits of early-stage testing without recruitment or coordination
He challenges assumptions about what counts as “valid” user research, arguing for faster, iterative feedback cycles powered by synthetic inputs.
Speaker 2: Michał Krajewski
Currently leading product at GOG.com (CD PROJEKT Group), Michał combines deep product knowledge with a data science background. He will demonstrate real, time-saving AI workflows such as:
Claude for compressing A/B test analysis
Lovable for prototype validation within hours
Deep Research for strategy-backed market intelligence
NotebookLM for synthesis of over 8,000 user survey responses
He also explains how Claude Code extends beyond developer use into the product space. His approach is tactical, not visionary—sharing tools that ship features faster and reduce PM burnout.
Why Attend?
Whether you’re a junior PM or a seasoned product strategist, this session goes beyond AI hype to show what’s working in live environments right now. You’ll walk away with hands-on workflows, exposure to tools you can use tomorrow, and new connections within Warsaw’s tech scene.
