Khimji Vaghjiani, CEO of Solar Gem visited me in February. Khimji is an Australian solar entrepreneur with his eyes on developing markets. He was in the US as part of the annual G'Day USA showcase of Australian technology.
Khimji posted his learnings here: Six things you should know before meeting with a US venture capitalist (Anthill Magazine). His post is based in meetings with US investors and his experience with the ANZA Technology Network program.
Bottom Line: If you want US venture capital investment, then become a "US" company (but keep the stuff that makes you great).
