One way that really worked for us in the beginnings was through participating to a local startup weekend or an event of that nature. This is a slightly less traditional approach, but one you should definitely take to your advantage. I’ve been a participant myself and now, as an organizer, I’ve seen many ides fully blossom and set sale to becoming a full-blown business.
You will find people you could bring on in your team, develop the idea further and have the chance to present it in front of established entrepreneurs who could fund it, or help you find someone who can.
