An E-2 would require some investment ($100k+) but Dutch citizens or Dutch-owned VCs but if this investment exists, then an E-2 could be a very good option. The other option would be the O-1 and as a founder of company that has had a good round of seed funding, you might qualify.

Would fund that we have raised count as investment in E2?

The fund would need to have been Dutch-owned for its investment to count for E-2 purposes.

How does a dutchman mingle around with local investors... and what series?
