THE COMPANY

B-Stock is the world's largest B2B re-commerce platform, connecting sellers and buyers of returned, trade-in, and overstock inventory. Our customers range from today’s top brands and retailers that want best-in-class inventory resale management to tens of thousands of entrepreneurs looking to purchase valuable merchandise for their resale businesses.

While the amount of returned and overstock inventory continues to grow, there is also growing pressure on retailers and consumers to adopt a more circular economy and keep products in use as long as possible. Accordingly, the need for re-commerce solutions - to find products a second life - has never been greater! At B-Stock we’re proud to play a large part in powering resale, reuse, and the circular economy through our platform: annually we sell over 130 million items across all categories and conditions, equating to 400 million pounds of inventory. 

We believe there is tremendous value in and demand for this inventory - no matter the category, condition, or location. With hundreds of thousands transactions completed annually, B-Stock gives buyers a simple and direct way to buy valuable products directly from retailers and offers sellers a technology-driven replacement for traditional resale methods, while boosting operational efficiency, recovery rates, and cycle time.

Led by eBay veterans and backed by top investors including Spectrum Equity, True Ventures, and Susquehanna Growth Equity, B-Stock shows no signs of slowing down. Our core values have shaped the company we are today and will continue to drive our success for many years to come.

OUR VALUES

Make Each Dollar Count 
Whether it’s the recovery amount or a buyer’s budget, money matters to all of our clients. And because each dollar matters to them, it matters to us.  

Take Our Work Seriously, Not Ourselves
Everything at B-Stock continues to grow - everything but our egos, that is. We’re not afraid to let loose and laugh (often at ourselves). 

Do The Hard Things Today That Will Pay Off Tomorrow
We’re willing to sacrifice and endure, fail and adapt to reach our long-term goals. 

Use Trust As The Best Measure Of Success
The trust we earn along the way is more valuable than money. Without trust from both our buyers and sellers, our business won’t succeed.

Find Strength In Numbers
Use our passion for data to provide value to our customers, improve ourselves, and develop new ways to delight our buyers and sellers.

Above and beyond discrimination/harassment based on “protected categories,” B-Stock also strives to prevent other, subtler forms of inappropriate behavior (e.g., stereotyping) from ever gaining a foothold in our office. Whether blatant or hidden, barriers to success have no place at B-Stock.
