We met Miki Agrawal, the co-founder of challenger to watch Thinx, at their New York offices to talk taboos, transport ads and taking on tampons. This serial entrepreneur has also started two pizza restaurants, co-founded two other startups and written a best selling book. Combined with her desire to sail headfirst into topics others deliberately avoid, Miki is an entrepreneurial force to be reckoned with.

In this video, Miki shares her advice to new challenger businesses starting out.

Miki Agrawal on launching a business.

1. Ask yourself what sucks in your world. Is it a problem for you?

2. Ask yourself does it suck for a lot of people? (Every single woman has experienced a period accident at some point in their lives)

3. Most importantly, ask yourself whether you can be passionate about this issue, cause or community for a really long time? If you can't see yourself doing this for ten years, then it's not the right business for you.
