Any European small-cap growth stocks catching your eye right now?

Hey everyone,

I'm interested in diversifying (and adding risk to my SP500&all-world etf dominated portfolio) my portfolio a bit and looking into some European small-cap growth stocks. I'm curious if any of you have any promising companies on your radar at the moment.

I'm particularly interested in companies with: Innovative products/services & Potential for significant growth. I am in my early 30s, so willing to take on extra risk and looking for long-term investments, not short trades.

Any thoughts or recommendations are greatly appreciated!
Thanks in advance!
