Dive Brief:

• Silicon Valley venture capital firm Kleiner Perkins recently led a $30 million investment round in online apparel resale site Tradesy, eight months after it led another, $13 million round.

• Other previous investors invested in this round again, including Richard Branson and Rincon Venture Partners. All told, the investment values the startup at $100 million.

• Tradesy is using the funding to beef up its staff, especially on its data science team, and its advertising. Google searches based on its product descriptions help drive the site’s traffic and growth.

Dive Insight:

Tradesy and its ilk are essentially niche eBays, focusing on resale of apparel and accessories (in some cases, just luxury only). Through its site and its app, Tradesy sellers offer a wide range of goods, from cheap lower-end clothing to higher-end wares. Its low commission brings many small brick-and-mortar resale and vintage stores into the mix. The startup says it isn’t profitable yet, but may be soon.

These vintage and used clothing sites are doing well now, but it’s hard to know how much room there is for how many sites. It will depend on how different the companies are from each other, how well their sites, apps, and searches perform, and how much of a problem they have with fake products and the grey market.
