Got cash? Great. Most high growth areas are short STEM graduates, short trades-people, but long on large companies who can outbid you for talent.
Got cash and talent? Awesome. Large companies have more than you and pay less vig for it. If you're lucky your business is likely to be acquired as it hits critical mass. If you're unlucky as the eye of Sauron notices you - all that easy big company money will crush you.
Oversimplified? Sure. There are exceptions, success stories and counter-examples. But understand that small business and small business job creation is not a priority in the US.

In agriculture the USGOV is literally paying farmers NOT to farm in some areas. The priority is wealth preservation and predictable returns for baby boomers and special interests who vote, and who control votes.
You know who wants to change this? Who wants to repatriate 2-4 trillion in liquidity back in the US where its very likely to benefit small business growth? The only high profile person I've heard championing this issue is Trump. He appears to be fighting hard for it in upcoming tax reform legislation. Opinions about this guy aside, if he gets his way on dollar repatriation there's going to be a lot of money available for investment.
