About the Challenge

I'm Marie, Senior Product Designer at Milestone Hafnia — and I'm so glad you're here for AI City Challenge Track 6!

As you work through the challenge and explore Training-aaS on the Hafnia platform, I'd love to hear directly from you. This thread is your space to share any thoughts on:

No feedback is too small — whether it's something that frustrated you, surprised you, or that you'd like to see improved, it all helps shape the future of the platform. I personally read and action everything shared here.

Thank you for taking the time — and good luck with the challenge! 🚀
