Doonyapol Srichan founded the brand PDM, starting with the creation of Phrom (pronounced "Pom," which means carpet or rug in Thai). Designed for hot cities, the rugs are easier to care for than traditional carpets and are suitable for the Thai urban climate.

Along with his partners, Doonyapol Srichan designed and created PDM Brand, where PDM stands for “Product Design Matters.” Their philosophy is not just about creating aesthetically pleasing images but also observing and studying user behavior to create a rug that meets various dimensions of lifestyle. PDM also collaborates with various brands in the fashion, furniture, and lifestyle industries, integrating designs, patterns, and colors from PDM Brand onto items such as bags, baskets, sofas, chairs, umbrellas, coasters, and even socks.
