Dive Insight:

After a skyrocketing IPO, investors have wondered whether Zulily could maintain its speed or even turn a profit. With the good news, the buzz about this little company -- that it's highly adept at the e-commerce game -- seems to be holding.

Zulily's strategy is an interesting one in retail. The flash-sales company pays no mind to the social-media adventures of the young, leaving behind name-brands for boutique ones and trusting moms have the time and the money to dedicate themselves to scoring finds that are special. Another key to Zulily’s success may be found in their IPO prospectus -- they believe that mothers browsing and buying at Zulily see it as time well spent.
