Good idea, start by being open to remote developers. I'm not going to relocate to SF, regardless of salary, equity, or how exciting the project is. I've worked remotely successfully for the better part of a decade, so I know it works. Slack, HipChat, Skype, etc. make the lack of physical presence nearly irrelevant.
Companies that can figure out how to create and manage a distributed team will have disproportionate advantages if the product is successful and they suddenly need to scale. Open-source projects are a good example of this.
