Zulily-logoZulily is a members-only site where moms can find discounted apparel, furniture, and toys for their kids. The company raised $4.6 million in funding last month, and now its site is live and ready to offer savings.

Seattle-based Zulily is taking the “private sale” model from sites like Gilt Groupe and Rue La La, where members get steep discounts on fashion. When I spoke to co-founder and chief executive Darrell Craven in December, he told me the model makes sense for reaching moms, because there are lots of mid-range and high-end boutique shops offering these products that want to sell to a broader audience.

Zulily’s first sale featured products from eco-friendly apparel company Origany, with discounts of up to 55 percent. Other early sale partners include Lex Modern and Baby Nay. Each sale is supposed to last 72 hours, although supplies may run out sooner.
