1. To close an angel round, use "mass syndication" by dropping names of interested investors without a lead and writing your own term sheet with low valuations and investor-friendly terms.
2. Approach financing as if you won't find a lead and raise money before you need it with deadlines and social proof from interested investors.
3. Get introductions to seed stage investors through AngelList and StartupList and have traction in the form of a product in the marketplace before raising a seed round.
