We offer directorship and advisory services to support your board. We believe in a hands on approach, spending appropriate time working with the management team so that they can focus on their jobs - managing to the best of their abilities. 

We can mould and develop implementable business strategies so that your company can move forward, using a set of guiding principles that, when communicated and adopted in the organisation, generates a desired pattern of decision making.  Bounce your investment ideas off us and let us refine your plan, growth trajectory and target strategy. 


Whether you are looking for seed investment or gearing up to an IPO, we have the network, credentials and insights to help you raise finances at each stage of your business. We know what investors and strategic partners want to see, hear, and feel in a pitch; we know how to dig in and elucidate the core opportunity of a deal; we know how to communicate the business fundamentals and truly sell the vision.  We have gone through the capital raise process several times with startups and have successfully raised funding from top investors. 


The effective management of your financial resources at the early stages of your business venture means that preparing budgets and forecasts is critical.  Financial models capture your vision in numbers. A solid model will show how much capital it takes to get your startup off the ground, as well as how much cash flow it will ultimately generate. We can build models that are credible, robust, and easy to use. 


We demystify the law with a pro-active and commercial approach. We have legal expertise to draft and negotiate contracts and navigate issues relating to IP, corporate and commercial law.



Together, we will craft your story, articulate your strategy and refine your presentation into the perfect pitch to make the impact you want on your audience. We do this by working with you to develop dynamic storylines, impactful content and astute answers to likely questions you will receive.


Maintaining the integrity of your public image is an inseparable part of your business, whether you’re a creative individual or a growing company.  It is not a case of 'one size fits all' and we are experienced in guiding companies to establish the right type of structure to benefit all stakeholders. 


We are open to assisting our smaller clients with a one-time investment to help the business propel or an ongoing injection of money to support and carry your company through its difficult early stages.


We’ve steered clients with a balance of legal, business, operational and financial advice that had clear execution and built-in problem-solving contingencies. Our holistic approach is essential to any company looking to grow and sustain long term success.




"Start-ups too often compromise on the legal aspects of their business: investor’s shareholder agreement, employee options, employment contracts, B2B contracts etc. Most often due to the fact that there is no legal service adapted to startup size companies; the legal advice tends to oversee the size, structure, problematics and challenges of such a type of company.


Castian Global has not only been of enormous help in structuring legal contracts for all types of business counterparts such as investors, retail clients and employees, but has also given key advice on how to integrate our specific needs and strategic directions in all our legal documentation. Cash’s experience and understanding of start-ups coupled with her strong strategic & business thinking makes her a fierce advisor you will want around your company table."

"Castian Global was there for our business when we needed to incorporate and execute on our ideas.  They helped us with everything from reviewing contracts and providing sound legal advice to building a credible financial model and prepping us for investor meetings.  Cash and the team worked closely with us to enhance our pitch deck, added value to the content of our website and strategised with us during board meetings.  Cash gave me the confidence to be a stronger leader in my organisation and I have certainly benefited from the wisdom she has imparted. We couldn’t have gotten this far without them!  Sharp, commercial, responsive but always personable, I would highly recommend Castian Global to anyone who is struggling to get their business off the ground or to just help you get to the next step."

"Having run a business in Singapore for a number of years, I found much of my planning and strategy development was organised on 'the fly'.  Castian Global sat me down and gave me the room to think creatively about my business and build a plan around the multitude of aspects that you simply do not have the scope to think about.  If you are IN your company all day every day, maybe it is time to get a new set of eyes ON your business to help you work towards tomorrow's challenges.  For a no nonsense assessment of your future plans, deep diving into your financial health and to aid in the roll out of those plans you always put off... give Castian Global a call."

"Transitioning from the corporate world to running your own startup is very challenging and I honestly 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 have continued to provide 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."
