All of the factors you mentioned are important but if you asked me to rank them.

1. Traction: as it proves that you know who to build something people want.
2. Team: as it's the constant that matters most as the business evolves.
3. Vision: as it'll help tell the story as to why you have the potential to build a $100M company in 7 years.

If you want comparables, just look at the top trending startups on Angel List ( http://angel.co ) and you can see what kind of team, traction and vision they have.

The more of those factors you have, the faster and higher quality of investors you will be able to get involved.

There's always exceptions to the rules, but normally this is how it works.

P.S. No one talks about relationships, but that's probably #1. Your ability to communicate and connect with people who can help with introductions to investors is a big part of fundraising.
