Founder Story

Hi, I'm Dogukan, the maker and developer behind Postier. I built this app to solve a problem I once faced as an Etsy seller.
Running a shop is a full-time job. Between designing, manufacturing, shipping, and ensuring every customer is happy, there is often no time left for marketing.
I know that feeling of being stuck. You want to grow enough to hire someone to help you. But you need more sales to afford that extra help and in order to get more sales, you need to market your products. But you don't have enought time to do marketing and you need... This goes on and on.
I built Postier to break this loop. Our mission is to give you your time back while keeping your shop looking professional. With Postier, you can get the sales you need to grow your business, hire that extra hand, and finally get your own life back.
