Besides the obvious "ask friends, ask family" what would you do?
I'm asking in part because I have a killer idea for a subscription-based model in a multi-billion dollar industry. It would be the only player in this industry, and the model has proven itself over and over across dozens of different industries.
I've had my share of success from an early age as an entrepreneur, but they have all been software or web plays. This is different, and my network of people aren't interested in this sort of thing.
I'm out of ideas.
Your other option, of course, is to seek angel investors and VCs. You may have some success there if you have some knowledge of the industry or product that they can't immediately duplicate. If you choose this route, be careful how you word this:
"It would be the only player in this industry"
That's usually a big red flag that the start-up doesn't know who their competition is. Adding "subscription-based" to the front doesn't instantly mean you are the only one in your industry.
