I work with Accel Partners in London (http://www.accel.com/#people/adrian-colyer), and after many years in CTO roles, I'm certainly not afraid of technical subject matter. A quick read through some of my recent blog posts should demonstrate that: http://blog.acolyer.org. There always has to be a good business opportunity too though, not just good tech. We help our European portfolio companies establish a US presence and grow the connections etc. that they need: Accel has been operating in the valley for over 30 years! Without passing judgement on this particular opportunity, I'm always happy to hear from anyone in Europe doing interesting things with technology, aspiring to build a significant business around it, and potentially looking for VC investment. Our recent investment in Weaveworks (http://weave.works/news/seriesa.html) is a good example.

Good advice from mseebach and kcorbitt still holds true though...
