I just read an interesting article on Business Insider.
Yossi Vardi, a well-known Israeli investor, warned startups to be careful raising too much capital early, because it makes you “cash flow negative from the outset.”
Sam Altman, president of top startup incubator Y Combinator, said something similar a year ago. His point was that raising money at very high valuations, especially early on in seed rounds, leads to high burn rates and messes up the culture — “Frugality is sometimes incredibly important for startups.”

That reminded me of the 40% rule for SAAS companies that I read about on Fred Wilson’s blog.
So, how much should you raise?
Although one size doesn’t fit all, a good rule of thumb is raise only as much money as your company needs to achieve major proof-points/milestones and practice frugality to keep a low cash burn rate, which impresses investors.
Don’t be tempted to raise as much money as you can. This is not a good idea from a financial strategy standpoint. Less capital gives you greater ownership over your company. It also forces you to take your time before scaling, which is a good thing.
You don’t need to raise a lot of money to be successful. Your capital efficiency (that is, raising what you need and no more) is a more telling indicator of your startup’s success than high valuation.
