Continuous Fundraising is a pretty radical idea. Basically, you never close your seed round since you're doing a note and the terms are fairly standard, so you just keep getting small checks from a large number of angels. Less pressure and hassle. Big win for entrepreneurs. As Naval says, you raise 50k/month for 6-12 months and you're all set.
re: Continuous Fund raising.
It is a pretty radical idea, and I really like it. It takes a bit of the pressure off the "One big round" model, and moves the focus to "Always be pitching" mode, which I think is probably healthier, and more productive for startups.
The only caveat I've heard of is when the startup runs out of money and is struggling. At that point, not having a lead investor who is keeping tabs on the company and who is willing to go the extra mile to raise additional capital for the company is going to be detrimental.
I can understand parallel-tracking some of these things, but if you do too much at once, don't you end up doing nothing well because you waste so much time task and focus-switching?
