New start up - How to begin?

This all depends on what type of product you have, what you need the money for and where you are in the development of your product and your company. The "traditional" funding route for startups is something like:

1. Yourself
2. Your friends and family
3. Angel investors
4. Venture capital

But this route certainly doesn't apply to all businesses in all situations. As to some of the other comments:

• Crowd-funded projects generally work best when you can promise something in return for a "donation". So if you're creating a physical product, something like that might work, but if you're creating a SaaS, it's probably not the best model for you.
• Incubators can be useful, but I wouldn't look to them as a funding stream. The application timeline can be long and you generally give up a lot of equity for a pretty paltry amount of money. What they do provide (and what they're designed to provide) is expertise and mentorship -- which are often the very things that money cannot buy. But they aren't investment vehicles.

Lastly, I'd caution you to get investment as late as you can (if you even need it at all). The longer you wait, the more developed your product is, and the more actual users you have, the better terms you'll get. In fact, depending on your business you might not even be able to get investment until you have actual customers. Having tested the product with only one user, I think you have a lot of work to do before you meet with an angel.

With my company, we made a conscious decision to bootstrap and while of late we've been kinda flirting with the idea of seeking some investment to help us grow, if we did end up going down that path (and I kinda doubt we will) we'd be in a much better bargaining position because we already have a proven idea and a proven user base to build upon.
