I have 4 of my own businesses, with more in the pipeline too:
1.) Venture capital/fund raising for biotech/pharma/renewable energy companies
2.) Renewable energy product development/commercialisation
3.) Import/export of traditional greek foodstuff (can import/export anything, but just focusing on the Greek stuff at present)
4.) Trade finance - lending money to businesses, mostly manufacturing businesses that rely on stock turnover for production of their goods
