“I highly recommend Castian Global, and in particular, Cash van Halder, as one of the finest and most competent attorneys in Singapore. I was particularly impressed with Cash's thoroughness and proficiency on all types of business law in Singapore and other APAC countries. Cash had been always accessible to answer the many questions we had and ensured we were kept abreast throughout the entire process. Castian Global is without a doubt, reliable and very professional.”

“Transitioning from the corporate world to running your own startup is challenging and I can’t imagine navigating this process without Castian Global. They have helped me with the tricky legal areas of setting up and running a company in Singapore, provided detailed guidance with effective feedback regarding the financial projections and invaluable advice in the investor prep/management areas. I will continue to partner with Castian Global and would recommend highly anyone else who needs help in these areas do the same.”

"I have been engaging with Castian Global since July 2019 and they have been extremely prompt, helpful and patient. Castian Global is equipped with a strong startup mentality and their team is able to understand the needs of SME entrepreneurs in Singapore. One valuable asset to why I always seek Cash’s advice and opinions is because she is able to provide legal advice with strong business angle and considerations."
