Management At BlueStone

Bluestone Co., Ltd. was established in 1997 by Mr. Chanos Nandavisai, the Managing Director, with an initial capital of 1 million Baht.

The company began as a distributor for several leading European brands and has consistently supported customers with reliable, high-quality engineering services and products in both hardware and software. Over time, we expanded into Home and Building Automation, establishing a Research and Development team to create products under the Bluestone brand, including EV chargers.

With a steadfast focus on delivering quality products and services, we have experienced significant growth. Our capital registration has increased from 1 million Baht to 5 million Baht, then to 10 million Baht, and finally to 50 million Baht in 2022. Currently, in addition to the pioneering executives, the second-generation heirs have also become a key force, with Ms. Praewa Nandavisai joining the management as the new blood of Nandavisai, demonstrating our financial strength and commitment to the future development of Bluestone Co., Ltd.

In addition, to prepare for future competition, Ms. Praewa is looking for new technologies and innovations to develop products and services to be more efficient. We are dedicated to maintaining the highest quality in our solutions to uphold our motto, “Quality You Can Trust.”
