Cooperation Over Competition
How two “Yinz” brands chose to work together instead of against each other
YinzMart.com has been Pittsburgh’s online marketplace since January 2018 — and has held U.S. Trademark Registration No. 5,591,860 for YINZMART.COM ever since. When Mac.Bid launched the YinzBinz Pittsburgh discount bin stores in 2023, YinzMart’s founder Jurgen Koster had a choice: fight the trademark, or find a way to work together.
He chose cooperation. Instead of opposing Mac.Bid’s trademark application or dragging another Western PA business into a legal battle, Jurgen reached out in good faith. The result was a formal Trademark Coexistence and Consent Agreement — a legally binding commitment that both YinzBinz Pittsburgh and YinzMart.com can thrive, side by side, without stepping on each other’s toes.
It’s the kind of deal that doesn’t make headlines, but it says everything about the values behind YinzMart.com: we’re here to build businesses up, not tear them down. There’s enough room in Pittsburgh for all of us.
