Unless you are a founder with prior successes that are notable or relevant to your new startup, the answer is a clear no.

There is no yes or no answer to this, risking sounding cliche but is mostly because it really does this depend on how good you are at pitching and how great is the idea and your ability/current resources to pull it off.
Is not unheard of ideas being funded, i think this is mostly through personal networks not through certified group angels, etc.

Things to consider:
The government now requires you to have a sort of investment request license that you have to apply for if you want to pitch publicly. - to strangers/investors/angels
check out: Steve Jobs Presentation Secrets (available through audible too) is great!
Try to go for family members. Even if is in the form of preorders. This helps you get a bit of cash for legal or dev expenses but also allows you to keep equity and show third osrties thst you have preorders (this at the end of the day when you are pitching is worth a lot!)

So go get some preorders before anything and with that you can better leverage potential investments :)

I have 25 years of experience working with early stage technology companies and investors.

I’m often asked about fundraising strategies for VC funds and angel investors. After raising capital and exiting from multiple startups and investing through 15 venture funds and dozens of angel investments I have seen thousands of deals.

I’ve found that the most productive use of time for both of us is scheduling a call through my profile.
