This week is an important one for pan-European startup accelerator Seedcamp, as it’s holding its annual 4-day event that brings together all companies it has invested in throughout the year.

The event will culminate in Demo Day, which is tomorrow, and will see Seedcamp showcase its portfolio startups to a wide variety of professional investors and press.

We’ll be attending Seedcamp Week Demo Day, of course, but after hearing the startups present one by one today over at the Google Campus building in London, we figured it makes sense to highlight the 18 companies we’ve seen already.

Tomorrow, after we’ve learned more about the startups, we’ll do a rundown of the startups we believe have the most potential to make it really big.
