Product Build Day // Reviews 

Very creative, very challenging and very humanized in a very artificial world.

Extra kudos for keeping everything on time- I find it very important, and because Im in the Product world that is always an issue with long meetings during brainstorming ext.

The workshop was the best I have attended yet! The people were great and very like minded. Marcin had one of the best processes of doing the task in terms of how we worked individually and as a team! I can’t recommend it enough! Good job!!

The day was great. The hardest part was making the decision to go and actually showing up. After that, everything just flowed.

The host, the organizers, and the mentors were all incredibly professional. Everything was really high quality. I loved being surrounded by so much creativity and having the chance to try something new.

Great opportunity to network, test out AI industry standard tools for free, challenge yourself to build a working product prototype within just a day - with the assistance of experienced mentors.

I wasn't sure what to expect going into Product Build Day, but it ended up being one of the most practical product events I've attended.

Instead of spending the day listening to talks, we spent it building. In just a few hours, our team went from an idea to a working prototype using AI tools, tested it, and pitched it. All while solving a real challenge for the city of Athens.

What stood out most was the people. It brought together product managers, designers, founders, researchers, and marketers who were all genuinely interested in learning, experimenting, and helping each other. The mentors struck a great balance between guiding and letting teams figure things out on their own.

It was also refreshing to see a hackathon focused on meaningful, real-world problems instead of hypothetical startup ideas. Building something that could actually benefit the local community made the experience much more rewarding.

If you're curious about AI-assisted product development, want to sharpen your product thinking, or simply enjoy collaborating with talented people, I'd highly recommend joining a future Product Build Day. I left with new skills, new connections, and a much better understanding of how quickly ideas can become real products.

Product Build Day was an overall fantastic experience. Organisation was top-class, comfortable venue, clear communication, friendly and effective facilitation. I've spent entire day collaborating with like-minded people, building and testing products, solving challenges and pitching to mentors. Learned a ton, networked a bit, made lots of connections and discovered valuable insights for my job. Lots of fun for a great price (0). Highly recommend!

"An amazing experience building and networking with brilliant minds. The room was instantly packed with learning and high energy. Builders, do not miss out on this, highly recommended!"

One day, four strangers, one brief. We shipped a working AI tool by mid-afternoon and pitched it by evening. No fluff, no theory, just building under real time pressure.
The format works because it forces the two hardest PM skills: cutting scope fast and testing with real users before you're ready. Uxia's synthetic user testing in particular is something I now think about every time I scope a feature.
Bonus I didn't expect: I used the tool we built to review my own job contract a few days later. Real output, real use.
If you're in product or delivery and want proof you can still build, not just manage, this is worth a Saturday.

It was great to take part in this event and have the opportunity to challenge myself. Thank you🙏
