Hello there,
As a business consultant we always ask our clients their expertise and it would be great to know more about your field of engineering. Technology sector has shown uptrends and interest from Venture Capitalists to Angel Investors, similarly life sciences, biotech, clean tech starts up are on list of many VC firms.
It all depends on your experiences, interest and thereafter a strong business plan making economic sense. Not every business requires huge investment as if the business concept is great, scalable and makes economic value then one can have funds under various options from financial institutes to VCs and other funders.
Better do market research,financial analysis and chart out a business financial before making a decision.
