Kids’ clothing exchange site ThredUp has just raised $7 million in series B funding from Redpoint Ventures, Trinity Ventures and former eBay CEO Brian Swette. ThredUp which was born here in Boston recently moved west to San Francisco after raising a series A round of $1.4 million. Newly formed VC firm NextView Ventures participated in their series A.

ThredUp was founded in 2009 by HBS grads James Reinhart, Chris Homer and Boston College graduate Oliver Lubin. The company aimed to be the clothing exchange site for men and women but it wasn’t long before an epiphany hit and a pivot occurred.

“Clothes don’t grow. Kid’s do.”

The company pivoted and moved to San Fran in September of 2010 and has seen incredible growth since then. ThredUp is actually expecting to swap its one millionth item later this month.

“We’ve spent the past year building a remarkable swapping experience for moms across the country. thredUP couples the simplicity of traditional hand-me-downs with a massive online network like eBay. We connect strangers in meaningful ways, to share things they no longer need and become better citizens of the planet,” said James Reinhart, CEO at thredUP. “We’re excited to have such a great group of investors on board who share our vision. I think this infusion of capital will help us bring thredUP to the homes of millions of families everywhere. We’ve just scratched the surface of what the peer-to-peer space can become.”

ThredUP will use this new funding to expand its team, refine the core product offering and grow its membership base. The company also plans to expand swapping categories such as toys and books. The team is also exploring international opportunities and loyalty partnerships with major retailers.
