Testimonials

"Working with Cash has been nothing short of a lifeline for our organisation, Seven Clean Seas. Her advice, expertise, availability and passion has been invaluable along the journey from startup to scale up. The standout moments for me was helping us successfully negotiate investment terms as well as the largest deal our market has ever seen. Without Cash, we simply wouldn’t have experienced the success we have!"

“I highly recommend Castian Global, and in particular, Cash Siersma, 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.”
