This week, we celebrate women entrepreneurs who are building startups and investing in startups.
By Angie Chang (Co-Founder & Editor-in-Chief, Women 2.0)

We at Women 2.0 love when women entrepreneurs exit startups and invest in other startups.

We especially love when women entrepreneurs who exit fund other women entrepreneurs, given that 15% of angel investors are women – and these women often have access and connections with women entrepreneurs (who lack traditional networks for investment).

Here are 5 women entrepreneurs to watch building their own companies – and helping to fund other early-stage ventures:
